I've trying to solve this problem for another user.

STOP: 0x000000D1 (0x00000001, 0x00000002, 0x00000000, 0x00000001)

The system is a Celeron 1300 with 128MB of RAM & 40 GB HDD.  The problem happens infrequently, but always online when opening certain websites.  The OS has been completely reinstalled, but the problem continues.  Windows Updates have been done, but did not help.

Most indications are that it is a driver problem, but how can I narrow down or identify the problem driver with no file or driver name info in the error?

Any help would be appreciated.

Are you going on the Internet through a NIC card? If so look at updating the drivers for it.

Yes it is a NIC, so I'll try that.

I have had this exact problem in two different cases.

Computer #1. I flashed the BIOS and it fixed the problem.
Computer #2. I removed one of the RAM sticks and it fixed the problem - turns out the RAM was bad...

Should be enough to get you started

Please take out all the expansion cards and restart the sys and check if u get the error.if it doesnt come up...start putting the expansion card one by one and after putting one card restart the sys and check if u get the error.
if u get the error on any of the card.then check the card on another slot ...if it still has the problem then there could be a problem with that expansion card.

That's interesting gambler.

It happens consistantly on the machine I am dealing with when the user starts a new game on, but otherwise he can join existing games with no problem.

He has also had it on some Chat websites.

Here is what microsoft says about it.

The Stop 0xD1 message indicates that the system attempted to access pageable memory using a kernel process IRQL that was too high. Drivers that have used improper addresses typically cause this error.

Interpreting the Message
This Stop message has four parameters:

Memory referenced.
IRQL at time of reference.
Type of access (0x00000000 = read operation, 0x00000001 = write operation).
Address that referenced memory.
Resolving the Problem
For additional troubleshooting suggestions that apply to all Stop errors, see "Stop Message Checklist" later in this appendix.

Stop 0xD1 messages can occur after installing faulty drivers or system services. If a driver is listed by name, disable, remove, or roll back that driver to confirm that this resolves the error. If so, contact the manufacturer about a possible update. Using updated software is especially important for backup programs, multimedia applications, antivirus scanners, DVD playback, and CD mastering tools.
For more information about Stop 0xD1 messages, see the Microsoft Knowledge Base link on the Web Resources page at Search using keywords winnt, 0x000000D1, and 0xD1.  

updated and comaptiable drivers are very important when running XP. Check your hardware with the HCL  If you hardware is not on the list it does not mean it won't work it just means it hasn't been tested by Microsoft and they won't Guarantee it to be compatible. If it not on the list check the manufacturer's website fo an up to date XP driver, if they don't have one you may be out of luck. This goes for motherboards and the bios too.

  My problem arises as Setup says along the bottom of blue screen "Setup is loading Files" changes to "Setup is Starting Windows" and stalls at this instance, so it is not easy updating drivers, etc with no O.S. installed.I don't know how to interprate this tech. info so I'm stuck here.

thanks all for the helpful posts so far; I've been having this issue as well. I've also received other BSOD's with different names, and I think I can see now that the issue is being caused by a driver accessing memory which it's not supposed to be. I also got a PAGE_FAULT_IN_A_NON_PAGED_AREA, but I did a check on my RAM for 12 hours with only positive results, so I believe it's a driver, not my RAM.

My question is this- now that I'm pretty sure that the problem is "a driver", how do I go about narrowing things to figure out which driver is bad?

For me, like for other people, I get this bug when playing online applet-based java games (at Yahoo! for me). I'm running XP Pro.

I heard about the "Driver Verifier Manager" tool (WINDOWS\system32\verifier.exe), but haven't found too much documentation about it; apparently it's supposed to be used for driver writers to make sure that their drivers are good. I think it can be used by consumers too, but perhaps someone might know how? (Or, perhaps, knows that it can't be used?)

Thank you all for the help.

I've had all the above problems. I flashed and upgraded the bios and seemed to help for a short while, but then it happened again, and much more frequently.

I finally broke down and took my PC to my favorite shop for help.

The problem was that my HEAT SINK FAN was not doing the job. That was replaced and my PC has been perfect ever since.

I have just spent the entire day trying to install xp.

The pc was win98 and something nasty happened and all the profiles disappeared, so I thought xp.

I had constant problems with the setup failing to read from the cd (Setup can't copy such and such a file) , so I swapped the cd and the disc, no difference. Eventually, the files read, then whilst still in setup, I got the IRQL_NOT_LESS_OR_EQUAL error and then a stop code (07, can't remember). Win98 installed ok, then blue screened.

I swapped the memory, and it all installed perfectly.

I think the whole thing got a bit cooked as I suspect the power supply fan was intermittant

At the run menu type sigverif this will give you a list of all the drivers on your system that are not signed by Microsoft. It is a safe bet that if the driver is signed by Microsoft, it is not the problem, try to find drivers that are certified by Microsoft.  Check out to make sure your hardware is on the list. It may not be supported by windows xp. If the hardware is not list on the hcl check the MFG.

I heard about same problem twice & one important I noticed then was, stop error was appearing after downloading & installing windows update for windows XP. In device manager it shows bang(red X mark) beside network driver under network adapter.Under network adapter, some entries can also be seen related to WAN Miniport. We need to uninstall all the entries under network adapter, but the problem is it will not allow to do that. Even if network card is reseated, it gets loaded up again. So please help me to uninstall the entries under network adapter and install only network drivers.

I have this problem as well. My BSOD seems to occur at the instant certain windows are closed. It doesn't seem to matter what program I'm closing either. One funny side-effect of this is that sometimes my browser (Netscape 7) will "reset" itself, loosing information such as home page and security settings, as well as logins\passwords I've asked it to remember. I think I have a bad set of nvidia drivers, as I updated them not long ago, and that timeframe approximately coincides with the start of my problem.

I get IRQL_NOT_LESS_OR_EQUAL and PAGE_FAULT_IN_A_NON_PAGED_AREA, it seems that it's more likely to happen when I'm using Photoshop or games (i believe that's because they're using ram extensively).

The thing is that I haven't installed any hardware for at least half a year, and any software for at least a month. This started happening after I shipped my PC on a plane and it got a little bit crushed... it still works, but sometimes even if I don't do anything, the BSODs pop up.

I checked everything - removed all cards i could, tried another video card. I thought it may be overheating but I have a temperature sensor. Still, leaving the PC open doesn't help, though it reduces temperature by 10 C.

It looks like this is a physical problem - maybe a microcrack somewhere in the motherboard or RAM. One thing is definitely true - if I don't do anything on my PC it is a lot less likely to crash.

You can try this to check out your Ram.
Memtest86 is a thorough, stand alone memory test for x86 architecture computers. BIOS based memory tests are only a quick check and often miss many of the failures that are detected by Memtest86.

It is a small freeware program.

robdot, I can tell you how I solved the problem in the end. It turned out that the PC was indeed overheating, as I've read in some other threads. A new cooler solved the problem, and it never happened since then (almost a year).

Whenever I play any game or use Internet Explorer my computer would just suddenly freeze and then a then a send error report to Microsoft window appears and the game just quits once you press Send or Don't send.

Also, I have been having these Blue Screens of Death all the time:

Stop 0x0000000A or IRQL_NOT_LESS_OR_EQUAL






Stop 0x00000026 or CDFS_FILE_SYSTEM

Now I can only boot into windows sometimes because I just keep having these blue screens of death!

To get further information about the error look in your Event viewer.

Look in the System or Application folder.  You can get to the Event Viewer via right click My Computer icon and select Manage.

Any errors logged in the Event Viewer can be expanded by double clicking on the error line.
Take any event error I.D. number and search for it on these sites.

Also check any "Information" line that mentions "savedump" and you should find reference to "recovered from a bug check".  This is the Stop Error that caused your problem.

You can also turn off "automatically restart after an error"  so it will just halt at the fault and display the full Stop Error and blue screen.

Right-click My Computer, and then click Properties .
On the Advanced tab, click Settings under Startup and Recovery .
Click to clear the Automatically restart check box under System failure , and then click OK . The error message on a blue screen should remain on the screen so you can record the error information.

Is your Bios updated?

These errors may be caused by defective physical memory or incompatible software which caused a hardware driver or service request for data that was not in memory.
If the error occurred after installing a device driver or application, try using Safe Mode and removing the driver or program.

Try Safe Mode (Do you have this problem in Safe Mode?). LAST KNOWN etc

Run the System File Checker program from the Run Box by typing.....Sfc /Scannow in it and have your XP CD handy.

I had intermittent stop msgs like that and it was a capacitor on the motherboard.  we figured it was hardware because I got a couple freezes booting before the windows screen appeared.  Luckly warranty covered it (tho it was a defect which they had declined to notify me about - even when I called them to ask about the problem - it was an IBM machine and I got the satisfaction of demanding of them, in my frustration, don't you people have any computers down there?!)

Hi everyone,
            I'm getting the blue screen of death 'IQRL_NOT_yada, yada' on my SOTEC laptop (128MB 700Mhz). The error is related to drivers, but I am unable to find any conflicts. I have tried disabling all new hardware, but to no avail.
            My question is this: How can I disable the driver verifier? All the documentation I have read points to this being the solution to my problem, but I have been unable to find any documantation on how to accomplish this.
            Please help me before I teach my laptop to fly.

Under File signature verification, click one of the following:

Ignore to allow all device drivers to be installed on this computer, regardless of whether they have a digital signature.
Warn to display a warning message whenever an installation program attempts to install a device driver without a digital signature. This is the default behavior for Windows.

I have been going thru constant crashing with IRQL not less than or equal - WinxpPro, SP1 and think I might possibly have it fixed (don't ask me how these fit together - I am no expert - but system is FINALLY running.....Without going thru everything I did ad nauseum, these are the things I did today that WORKED!:

1. Enable APIC mode in your bios - DISABLE BIOS VIDEO
2. Download updated video drivers from Windows Update (I finally determined I was having a video problem) -- If they are rundll.exe inclined, disable them in msconfig.exe on startup..
3. I edited (search for it, right click on it, and in properties go to memory.....Mine was 0'd out after downloading drivers?? So, I changed the initial value to auto,  initial environment to 512 (my one memory stick left - removed all others), changed expanded memory to the max value, extended memory to auto - uses HMA, and ms-dos protected memory to auto.  My machine is speeding right now -- of course, it will probably blow up -- but, it is NOT crashing, and is behaving better than it has in months. If anyone knows if my changes are dangerous, pls let me know, other than that, this ended an EXTREME long time of frustration for me. Hope this helps -- TLC

back to add to my origional post. I may add that when i am printing sometimes i have the problem with xp crashing. i have recently installed SP2 hoping that the problems may have been solved but it has not.
I am wondering if this is a usb problem?
I have the latest drivers for my Globespan 070 dynalink modem but i may add they are from mid 2000. As this is a usb Modem i also have usb cannon printer usb webcam/digital camera usb joystick all connected permenantly but the printer does turn its usb off after a few hours of non use and i have to pull the power plug out and back in to activate it. It seems to me that it maybe usb drivers or usb drivers conflicting with another program. When i check in System tool there are no conflicts or problem devices showing up.
Cheers keith52. hope someone may have a helpful idea.

I had the exact same problem about 2 years ago, with 2 systems, altho they where cheap boards, so I didn't think much of it. Both where socket A's, was buiding 2 systems for a customer, tried win98se,ME, 2000, xp home and Pro. I even tried to install Linux. Anyway, I couldn't have been bothered looking for problems, so I put both the systems away, and forgot about them (been busy) until about a year ago. SO just out of intrest I put one together, the exact same systems, nothing changed, same RAM, Hard drive, floppy, cables, everything. Anyone hazard a guess as to what happened ?................ yes, nothing. Everything went just swimmingly, both systems, and infact are still running. Seems like the fairies where in.
I know this isn't gonna help anyone much, but still thats the way it happened, so I done nothing, and it worked ???
I have had other systems do the same things, and mostly they all have a different fix, almost all the fix's suggested have worked for me on 1 system or another, first thing I usually check is the graphics card, change it and see what happens, Ram, also, leaky capacitors are always a good bet,and CNR modems. I usually find that its hardware related as opposed to software, altho don't rule software out. Mostly I find if its software, firewalls and antivirus programs are usually at fault.
Hope this helps someone a little.

I started a thread - Thread779-805498, where I asked a question about my XP Home randomly crashing.  I would get the BSOD with "DRIVER_IRQL_NOT_LESS_OR_EQUAL" error with stop codes usually 0xd1, but sometimes 0x0a, 0xfe, etc, with the notation usbhub.sys - Address.... under it.

Eventually, I found the problem occurred only when the connection to my ISP was turned off but my USB cable modem was on and plugged in, so that I was still connected to the cable company.  I now work with my ISP connected all the time (and trust my firewall). The problem reappeared only once, after for some reason my ISP got disconnected and I didn't notice it (I was preparing a Word document at the time.)

It seems to me that this error covers a lot of things, and is a completely useless diagnostic tool provided by Microsoft.

I've been getting an error when I boot up some higher end games: America's Army, Battlefield Vietnam, etc. It gives me that blue screen msg DRIVER_IRQL_NOT_LESS_OR_EQUAL. I have been told that this could be alot of things but I'm thinking its my graphics card (NVIDIA Geforce3).

What is odd is that it has gotten progressivly worse. At first it was just for America's Army. Then Battlefield. Then Counter Strike. Then pretty much any program. It has gotten worse for about 2-3 weeks and now it's at the point where I can play no games. I'm suffering withdrawl! I'll try to do what has allready been posted here, but help for my specific situation would be most appreciated.

BTW, when I go to the BIOS settings by pressing F2 while the computer is starting up, I don't see any 'caching' or 'shadowing' that the error suggests that I disable to fix this problem. I also just downloaded the drivers for my video card which was updated April 10. I'm stumped and my computer guy is away will May 9th :(

This thread has been chugging along for almost two years and several posters have reported possibilities that have worked for them, so you might have some luck by trying some of their solutions.

As for turning off 'caching' or 'shadowing' in your bios, and not being familiar with your bios, I can only report that I have not seen any fixes in any posts in this forum  referring to that as a confirmed fix for anything.  Often returning settings in the bios back to Default may help more than disabling this or that.

When you have updated your drivers was it from the manufacturer's site or Windows Update?  A lot of problems occur with drivers (especially video) from the Windows Update site.

I had this problem and was trying to find a cure for a while. The solution for me was to change the memory, as my motherboard only supported DDR 333 With a 333FSB CPU. This could be the solution for you.

Well I have to say that my problem is fixed. When i installed the usb modem it said to install on a usbport 1.1.
I changed the modem to USB 2.0 and the printer in the USB port right beside it.
No more crashes but the funny thing now is that the great microsoft sidewinder gamepad( which does not have drivers for windowsxp)  no longer works and i have tried it in every other spare port) i have 6 ports for usb.
funny every other usb joystick and game pad (non microsoft) come with usb program installation for their products.

i've had this stop message too and it just gets prog. worse. Now its blue screen w/ "...oflessorequal..." PLUS "msconfignot working" or something. I used to get some time before the beast powered off ( no shut down) but now it won't even boot up. i just got DSL  (I happened to do what everybody here has been recommending-dissconnecting ethernet card, uninstalling DSL software (and P-to-P progs) etc.,) and It has done nothing.
It only gets worse! Any advice???
PS. When I enter safe mode It lists every driver in my system-or what seems like it-and then shuts down. Also would Sys. Restore do anything and would I be able to keep files downloaded since the problem began?

You could try using the "Last Known Good Configuration" option from Safe Mode entry screen.

If you can't enter Safe Mode or Normal Mode then System Restore is unavailable to you.

What were you able to do to fix it?  What may you have done to cause the problem to return?  Is it a problem with just 1 game (refresh my memory, this thread is getting a bit hard to follow).

If you have a point in time where you were happy, try using System Restore to return to that position.  If your lucky and it works for you, then keep a record of what you do to your computer as it is used, see if you can detect what is causing your problem.

I had the same problem,and I have fixed it. The commonality is that these web sites that give you BSOD each have  default music,and the soundblaster software was the culprit. Uninstall the software and let XP restart and install the drivers and the problem is gone. At least it was for me.
Tomking (TechnicalUser)
27 May 04 12:30
BSOD when on the internet,which happens infrequenty,can be caused by the sound card drivers as these web site that I have encountered have music problem only happens on music sites. Get new drivers,and many drivers are in the Xp database. Took me awhile to find this so I wanted to pass it along.

Hello, I get the DRIVER_IRQL_NOT_LESS_OR_EQUAL error also. I have read this whole thread and have just been confused. I recently bought a new system and started getting this error as soon as I installed BT Broadband (within about 30mins online) I took the computer back where I bought it and asked them to look at it, but they found nothing wrong with it saying it works perfectly. I only get this error when I am online and they didn't have the facilities to connect my computer to the net as they used a cable connection and not ASDL like BT. So I then ring BT and ask for advice and they tell me that it's nothing to do with them and that I should contact the manufactures of the PC. They also suggested that I ring Microsoft and ask for help. I ring Microsoft but then they asked me for a refference code for the version of windows I have running. I started giving them the number then put down the phone because I copied version of XP Pro. Basically I fell like I am going round in circles, BT cant help, Comptuer Manufacturers cant help and I cant ask Microsoft again. You guys on here seem to know exactly whats up and have had experience with this particular problem. The only thing is I dont understand how to do some of the things you suggest. Is there anyone who might be able to run me though things in a slightly more elementary way? Thank you

Regards Jonathan

Is your version of XP genuine? Can you clarify the comment "I started giving them the number then put down the phone because I copied version of XP Pro"?  

If it is a (bad) copy then your version of files may be the problem.  Ethically speaking this site has certain policies and we may not be able to help you if your version of XP is not a genuine version.  Any attempt to do so might result in this whole thread being removed by the site management.

If your machine is still under Warranty, you might suggest that the people you bought it from attend at your location to see the problem, as they don't have the correct Internet connection.

Hello all,

Well, this little problem seems to have been running for some time now, pleased I'm not the only one who's been having bother with this!!

I keep getting the dreaded blue screen with random fault log's;





Etc, etc, etc.

Well, when I say random perhaps I should explain a little more. I can get my PC [O/S Windows 2000 btw] to fail quite easily either by running either disk clean up, anything using flash player or by running Spybot, it also does it sometimes – not always – when running WMP. The trouble I’m having is that it’s never the same fault log to each application. I could be running a flash player game and get  DRIVER_IRQL_NOT_LESS_OR_EQUAL, reboot and get the same message while trying to run a disk clean up. Several minutes later while maybe running the same flash player I then might get PAGE_FAULT_IN_NONPAGED_AREA or perhaps UNEXPECTED_KERNEL_MODE_TRAP. Nothing appears to have any continuity to it and it’s very random, well, to me anyway?!

Now, I’ve read through all the post’s and tried several things you chaps have suggested but the main things I seem to see that keep cropping up in the thread are things that I have, ie Zone alarm Pro, Normans AV, Nvidia, Geforce graphics to name a few.

I’ve done the usual stuff, downloaded all new drivers, up-dates and any thing else Windows recommends, all to no avail.

One thing I’m fairly certain is that it’s not an overheating/fan fault as my PC can be turned on for 10 hours, browsing the web, doing documents etc, etc, and won’t flicker until I run anything stated above. Even if I run these things in safe mode fist thing when the PC is still cold it will still bail out and it’s nowhere near to getting even warm, never mind hot.

Another thing I have noticed [ not sure if it’s irrelevant and sorry to waffle on ] but my Zone alarm Pro say’s I do not have any anti virus software running? It say’s it does not recognise any and can not detect any, yet it’s there, running away happily in the corner?!!
Just wondering if it was a possible conflict of interest between ZA and Normans?

Cheers for putting up with this post!!

Does ZoneAlarm now include an Anti Virus scanner too?  Running two virus scanners (at the same time) is a bad policy.

Is Spybot the latest version, and not a beta version either?

With all those errors I would also look at checking your RAM.
REDROUTE1 (TechnicalUser)
7 Aug 04 18:45
sometimes if i had a hex code to go with the stop error i can exactly pin point the exact error.but with the driver error i would suspect a faulty piece of hardware and thus all the other blue screens would branch off that single suggestion is to remove all your cards from the mother board (one at a time) and try to simulate the issue.if the problem comes up again then you know you need to keep pullin out the cards then eventually get up to memory and then you will eventually find the weary certain blue screen codes also refer to the IDE controller on the mother board so if that is bad then the board is bad.
ToonNut (TechnicalUser)
8 Aug 04 6:32
REDROUTE1, I think you may be right, I possibly have a hardware fault as I now have something completely different [ leading to same blue screen ] . My PC will no longer play music through disc detector 2 but it will play it through Creative Play Centre or WMP? When I go to Control Panel and Audio HQ it say's the driver is not installed, but I've tried installing it several times yet it still won't recognise it? I think I’ll go for the removal of the cards as suggested, see what happens. By the way, here’s an example of a fault log, for what good it may be?
DRIVER IRQL NOT LESS OR EQUAL 0x000000D1 (0x6402809F,0x00000002,0x00000001,0xBFE244D3) Address BFE244D3 Base At BFD04000, Datestamp 3F820145_NV4_MINI.SYS.

Linney, are you suggesting I dump either the AV prog or Zone alarm? If so, which one shall I keep? Spybot is the latest version by the way.

Before I do anything, can someone please have a quick check to see what their Driver Verifier Manager has under the “driver status” tab and “settings” tab for me please?

I’ve just checked mine and there’s nothing at all under the “status” tab, just a blank box? There’s also 111 different drivers under the “settings” tab but there all “disabled”, surely it can’t just be a case of enabling all these drivers, can it?

What harm can I do to my O/S by enabling these drivers?

As for ZoneAlarm and Normans AV, neither of which I am too familiar with , I just meant for you to make sure they are not both running virus scanners at the same time.  I had heard that the new ZoneAlarm was moving into scanning for virus infection, I have also seen that there has been a lot
of teething problems with the new ZoneAlarm.

Hmm, now I'm really confused, aspirin anyone?  

Right, I’ve had a look, there’s 77 “things” in there?

All but two are disabled, the rest are either running at the moment or are manual, which I assume would become active when called for?

The two disabled are;

1.    “Messenger - Sends and receives messages transmitted by administrators or by the Alerter service.” Which has two dependencies, Remote procedure call [RPC] and Workstation.
2.    “Routing and Remote Access - Offers routing services to businesses in local area and wide area network environments.” Which has two dependencies, Net Bios group and Remote procedure call [RPC]

Is there any way I can make a copy of this list in full and would it be of any help to anyone?


REDROUTE1 (TechnicalUser)
10 Aug 04 18:24
that is normal as long as those are the ones disabled.  if u dont have any sound then it must be a driver issue.if u have a sound card and u also have integrated sound remove the sound card card and then install the drivers for the onboard sound.if you dont and u only have onboard sound then mother board is toast or you can try to buy a card to get past it.

well the 0xd1 is mainly a driver issue.but the problem is somewhere within the software if one program executes the music program but the other doesnt then i would like towards reinstalling the program not the driver.if the driver was at fault then their would not be any kind of sound coming from your system.let's keep it simple then we'll work toward the unexplainable.

Most games crash when they're missing the latest XP patches or drivers obtainable from the manufacturers site.

I assume your error is an IRQ one?  If not to get further information about any error look in your Event viewer.

Look in the System or Application folder.  You can get to the Event Viewer via right click My Computer icon and select Manage.

Any errors logged in the Event Viewer can be expanded by double clicking on the error line.
Take any event error I.D. number and search for it on these sites.

Also check any "Information" line that mentions "savedump" and you should find reference to "recovered from a bug check".  This is the Stop Error that caused your problem.

You can also turn off "automatically restart after an error"  so it will just halt at the fault and display the full Stop Error and blue screen.

Right-click My Computer, and then click Properties .
On the Advanced tab, click Settings under Startup and Recovery .
Click to clear the Automatically restart check box under System failure , and then click OK . The error message on a blue screen should remain on the screen so you can record the error information.

Run the DxDiag command from the Start Run box for further clues.  Make sure DirectX and Windows are up to date too.

DirectX: Description of the DirectX Diagnostic Tool;...

263039 - Games: How to Troubleshoot Display Issues;...

HOW TO: Verify Unsigned Device Drivers in Windows XP

To check conflicting software.

310353 - How to Perform a Clean Boot in Windows XP;...

316434 - HOW TO: Perform Advanced Clean-Boot Troubleshooting in Windows XP;...

Some general things to try.

See if System Restore will get you back to a restore point before your problem with your games.

Try Safe Mode (Do you have this problem in Safe Mode?).

Try running ChkDsk to check your drive for errors. Right click your Drive icon/ Properties/ Tools/ Error Checking.

Run the System File Checker program from the Run Box by typing.....Sfc /Scannow in it and have your XP CD handy.

If they don't work you could try repairing windows itself by running it over itself.  You will lose all your windows updates but your files will be untouched.  That would not be a problem if you took the opportunity to install SP2 at the same time.

I get the same type of bluescreens all the time, but only after I've installed the drivers. I have formatted C: many times, and before I install the additional drivers in Device Manager, the PC works perfectly allright.
However, after installing these drivers, I get the message:

DRIVER_IRQL_NOT_LESS_OR_EQUAL then something about usbuhci.sys

and sometimes also:


Now, I've read all threads in this forum, and tried everything in my power to find out what might be causing this error. I have flashed the BIOS and installed the newest up-to-date version, I have updated all drivers, I have even bought a new motherboard and new memory.
When nothing of this seems to resolve the problem, and I have tested everything but the CPU, i believe this is software related (not hardware), or rather driver-related.

Now here comes the weird part: When I use a network cable and my ethernet card to connect to the internet, everything is working if I unplug the Wireless USB LAN Adapter. I don't have anymore USB hardware attached to the computer, so I do not know whether it's the USB adapter or the USB ports on my motherboard causing this.

Could anyone please come up with a solution? I have tried all my friends, the retailer, the manufacturer and no one knows how to fix this, but I have a feeling it's the USB drivers or the USB Adapter drivers.

SP2 specifically makes a lot of changes to USB drivers and the way they work - as you can see from the fixes on SP2 here - Most companies are releasing SP2 updates for their device drivers however...

Weirder and weirder is that the BAD_POOL_CALLER error and some other errors can be stopped by unticking Asian Languages in Control Panel / Regional & Language Options / Languages.  It's fixed some of our problems - as long as you don't actually need Asian Languages!

So here's my problem. I get the BSOD with the following:
DRIVER_IRQL_NOT_LESS_OR_EQUAL followed by the stop:
0x000000D1 (0xDC4C0108, 0x00000002, 0x00000000, 0xF70E18B1) followed by w22n51.sys - Address F70E18B1 at F70BC000, Datestamp 3ff54d71

So I've isolated the problem, based on Microsoft's self help and playing with the drivers to my computer's wireless drivers. Problem is that my computer tries to do a start up error check, but never makes it through because the computer will BSOD and reboot. Without being able to actually enter the GUI, I can't disable and install new drivers. Any ideas of how to get around this? BTW, safe mode keeps getting snagged on a file called gap30kx.sys. I know I'd be able to do everything from safe mode, but is there a reason why it gets snagged on that file?

Have you considered loading the Recovery Console and using the "Disable" command to remove the faulty driver?

You could also try the ChkDsk /r   command.

As for "gap30kx.sys", there are no hits on Google concerning that driver or file, and I could not find it on several checked Windows systems.

If they don't work you could try repairing windows by running it over itself.  You will lose all your windows updates but your files will be untouched.
