Windows XP Pro.


When I first put the PC together, the pc ran fine for a while however on a random basis, I was getting a few BSOD messages, IRQ_NOT_LESS_OR_EQUAL was the most common one. I noticed that the Power Supply is not SLI certified. I have removed one video card. I have tried running memtest86, which ran for 12 hours, with no errors. I have also updated all drivers. Removing 1 video card, helped for a while. Sli is disabled. Now the computer crashes right when it gets to the desktop. Something else I noticed is that there is a yellow light on the motherboard that is on, however I can't find any documentation about it.

I am not able to view the BSOD, because the pc reboots automatically and auto reboot is NOT enabled. There are a few things I will try tommorrow because I give up for tonight.

Things I will be trying tommorrow: running with 1 stick of ram, then the other, and updating BIOS.

In the meantime, can anyone else help? Any suggestions?

Look in Safe Mode, if you have SP2, there is an option on the screen to disable automatic restarts (I assume a once only setting per startup, but I'm not really sure).

This is a long thread about IRQ problems, see if there is anything in that which helps you?

DRIVER_IRQL_NOT_LESS_OR_EQUAL error

My motherboard has a blue light, looks pretty, but I don't know what it means either, probably some indication of power flowing through?
