Computer shuts down / restarts when it wants...

Hello, I'm gonna get straight to the point...

My computer either shuts down or restarts just out of nowhere...This all started about 4 months ago, right after we had a D.U.I. crash into my mom's office in a SUV, on the other side of the wall from where my comp is. Anybody would have been killed or seriously hurt, had they been in that room... Anyways, my computer was not on at the time, but I swear a bad surge or something must have tampered with my comp (I have average surge protector for plug-ins), because the cable modem & router were in that room too. The cable modem was fine (dunno how), but the
router was CRUSHED. The room was also really wet because the heaters use hot water.

My Ethernet card is intergrated, and no longer works after that night. Now this all may be coincidental, but I'm skeptical on that part... Problems were annoying but minimal (gradually getting worse) for about 2 months. Then it started getting BAD...anytime from as soon as it got to desktop, to 5 min or 5 hours, it would either shut down (with power light still on), or restart. Most the time it seemed to restart more, but it don't seem to matter now.

But here's the tricky part, get this... The damn thing ran great as long as a game was running! Not once did it do anything while in a game, whether it be simple ol' Alpha Centuri, or power suckin C&C Generals, Quake 3, ect. I used to run Alpha Centuri and Alt-Tab it, just so I could mess around in desktop and do things I wanted to do. I couldn't (and still don't) understand it! So one day I just stopped using the comp, just because I was being stubborn about the fact that if it wasn't gonna stay working without running a game, I wasn't gonna use it at all (or at least until I got money put together)...

About a little less then a month layter, I was rearranging my room and moved everything around a bit (including comp). I was happy with new look of the room and gazed at my newly arranged, clean comp-desk. I was itching to turn it on so I did. Everything loaded fine, but I wasn't gonna get my hopes up just yet, so I went in the livin-room to see what was on the tely (vision). I come back after a couple hours to find that it is still running strong. So I'm all stoked about it and end up staying up for 2 days doing stuff on it, running clean as a whistle, I finally shut her down for the night. To my amazement this goes on for almost a month, runnin the internet (through USB) and everything I could think of!

...Untill one morning I turn it on and I have a mess of serious problems, that I got off the net. My computer was sick, I did all I could to remove whatever infection I had gotten, but I realized I couldn't fix it. So I re-installed Windows 2000 Pro (without Service Packs this time), went very smoothly, and then a few hours layter I find that my comp is off (power liht still on). This happens a couple more times within the next day, but then early this mornin I started it up and AS SOON as the screen was about to switch to the desktop it would restart...this happens several times in a row, even shuts down a couple times, so I try it one last time and it runs fine as I type this very sentance. It's been fine for hours now.

One interesting note is, I can tell when it wants/attempts to shutdown/restart, cause it will make a strange sound, somewhat like a faint tick. I'm not yet sure where it comes from as it is quite unpredictable and patternless. The last failed attempt to load to desktop, it ticked 3 times in a row like, tick..tick...tick...tick (last one shutdown)...That however was a first...Now that I think about it, it makes that faint tick as soon as the comp turns off, normally or not.



† Summary †

There you have it, I'm sorry if this was a long post but I just wanted to be as detailed as possible, because I absolutely NEED to find out whether it's my Mobo, Power Supply, or somethin else. I truely appreciate all ya'll's time and effort to help me figuer this DEMON out, cause it sure is hell.



P.S.
I'll try to stay in check with the forum, but it's up to my computer on whether or not it wants to run...

Just in case there is some possible problem with the power at the source (wall plug) i would suggest you get yourself a UPS. Who knows, that could even take care of your problem.

Also, if it gets down to you having to completely start from scratch, dont just reformat your hard drive. Download the hard drive diagnostic prog from the hard drive mfgr and use the "write zeroes to your hard drive" feature. I have found that this will take care of most virus\trojans\malware that may still linger after a reformat. This is just my opinion, seems to work for me.

Personally, i feel there are just way to many variables in this one, such that, if it were me, i would simply start all over again, rebuild the system from scratch and re-install the os, drivers and programs. And if you do, dont forget the "write zero" program i mentioned above.

If you want to troubleshoot first, then i would suggest you take all hardware that isnt absolutely needed out of your computer, all pci, usb, whatever isnt needed to boot up.
If your computer is ok for any number of hours then, of course, one of your add-ons is the problem.
If it is still acting up then I would try a different:
power supply
video card
test all ram using "memtest" that you can get via google.

If you cant try another power supply then, if you have a multimeter you can get your hands on a tutorial on how to troubleshoot your power supply, using google you can find one at techrepublic and other places.



Good advice + great people = tek-tips
