STUPID PROBLEM:Cold Start-No XP, restart=XP

[midsummas]

Whenever I start up my computer cold, PC refuses to go into Windows, shows POST and everything, just goes into black screen with green light on. CD drives are able to be ejected but no OS. I then push restart button and Windows will start up but not b4 it goes to Command screen. THis problem was here b4 and was solved with new 300W Power supply and new installation of XP. But now installed XP 4 times and problem appears again. My Specs are
AMD Duron 1.10GHZ Processor
512mb RAM
GeForce FX5700 256DDR
80GB Seagate
30GB WD
Elitegroup k7s5a Motherboard
LITEON DVDRW411S
MATSHITA DVD_ROM

Solving of this problem would be greatly appreciated

It still looks like not enough power...

I agree with temporello

This is sign of a PSU problem, very common, the components withing the PSU don't start working properly until they are warm, try just going into the BIOS for a minute or so then restarting if it goes straight into windows then it you might want to consider upgrading your PSU.

Also the FX5700 is going to draw more power.

I'm no electronics wiz but I have heard something about the initial load put onto the PSU being to much when it's cold but ok once it's warmed up.

I've just checked out your machine with the calculator above and the result is well over 300W...

Just a thought:
On older computers the Fast Bootup had to be disabled to run the Memory check which gave the hard drive sufficient time to get up to speed before the BIOS detected it.

This can be related to issues like settings in the BIOS to do a Quick Start bypassing a memory check and a check for Drive A (Floppy). Sometimes if you slow down the boot process by adding these it helps. No Guarantees.

There are other settings in the BIOS like Wake on keyboard and mouse movement, and Network, and Modem that use extra power in the Negative 5 volt range. Some power supplies are lacking in this area. Sometimes if you turn these off it helps.

Other settings in the BIOS that can cause issues are settings for Hybernation which affect how the computer restarts after a power loss. I also sometimes turn off all the Green Monitor and Hard drive settings in the Power Management part of the BIOS.

I am running XP on a PIII motherboard with minimal RAM (128 Meg) and an old 250 Watt power supply with a 1.2 Gig Celeron. The only way I could get the computer to keep going was to turn off most of the fance nice to have options in the BIOS.

If you do not like my post feel free to point out your opinion or my errors.

Strange, I just placed a used K7S5A (worked the day before) into a spare computer. Same problem with Win98SE. I just got into the habit of turn it on, wait until it freezes and hit reset. Since it doesn't check the harddrive when I restart, it must be freezing up before Windows.

Thnks for replying guys. Off to buy a new Antec case with 380Watt power spupply in Gloss Black. Hopefully this will solve the problem as it seems to be a matter of getting warmed up b4 I can enter Windows

Forgot to mention: the system with a problem has a 400W P.S.

Put in a bootable floppy, do a cold start. Does it boot? If so, I would suspect something along the lines as posted by Blujacket earlier.

If the monitor connects to the PSU then your system requires around 75 Watts more!
