I just finished building my new system, and it keeps giving out blue screens at seemingly random times. It boots up, and all looks well. But after a while, the blue screen comes up. When the computer reboots, the chkdsk utility runs. And it usually says stuff like 'correcting minor error in such-and-such' or 'deleting such-and-such'.

Ok, I changed the memory voltage to 2.0, and started the computer up. It ran the chkdsk utility again, and I recognized wmplayer.exe in the list of stuff it was deleting. Then it booted into Windows, and sure enough, wmplayer.exe wasn't there, so I reinstalled it. But then I tried to play a game, (Oblivion,) and the screen was totally black, but the sound was working. So I hit ctl-alt-delete, and a thing came up saying something about video drivers. Then the computer froze. I pushed the power button to turn it off, and then turned it back on. And it booted up fine. Then I reinstalled the video drivers, and tried playing Oblivion again, and this time, it worked - for a while. Before long, another blue screen came up, saying something different this time:
I don't think your PSU is beefy enough. I'd consider a small fusion powered reactor to generate more stable power. And once I took care of that... yeah, I'd test the memory. If you still can't nail down your problem, go with 1 video card and just one memory module, remove the sound card and ditch the optical drives as well... anything to simplify your setup.
I just tried taking everything apart, and putting it back together, per my dad's suggestion. I wiped all the hard drives clean, (didn't have anything very important saved on them,) and reinstalled Windows. And it worked just fine. I installed the video drivers. Worked just fine. I installed the sound card drivers. It started installing, but before it finished: poof! Blue screen. I hadn't remembered to change the setting to stop it from automatically restarting, so I don't know what it said.
However, I remember when I installed Windows the last time, that it gave a blue screen when installing the audio drivers. So, does that mean it's probably a problem with the sound card and/or the audio drivers?
I uninstalled everything from Creative, and then rebooted. I sat around for a while, just playing Solitaire and stuff, and there were no blue screens. Then I started running Stress Prime 2004, and one hour later, it had no errors to report, and there were no blue screens. Then I downloaded the latest drivers from the Creative website, (I had been using the ones that came on the CD,) and the installation went flawlessly. So now that I have sound again, I'm going to try running Oblivion again tomorrow, (getting rather sleepy right now...) and see if it crashes again. If not, then I guess I just got a bad batch of drivers on the CD...
If it crashes again, eliminate the add-on cards leaving only the video. if that still crashes, disable onboard audio, network, firewire, etc. If that still crashes, something wrong with the mobo. If not, enable a feature in bios & boot xp. If it checks out, enable one more until all are enabled. Do boot xp each time. Last install your pci cards one by one & boot xp each time to verify.
i had the exact same problem "DRIVER_IRQL_NOT_LESS_OR_EQUAL" two weeks ago when i bought my new system... after two weeks of research i managed to solve the problem.
This error is an IRQ (Interrupt Request) error... its basically to do with USB devices being shared or a NIC (Network Interface Card aka Network Card) related problem............the problem with my system was that i had a modem connected to the mobo via USB. I chucked the USB connection and connected the modem via Ethernet cable. Solved the problem. I suggest you try the same.
