Dark_Crusader17, i had the same problem... and to tell you the truth... i have NO IDEA how i fixed it... the IRQ_NoT_less_or_equal is an interrupt error usually when your video card is sharing an IRQ with something else, usually the PCI card that is closest to it...so I removed all my PCI cards and i was still getting it, i didnt have any PCI cards installed... so i reformatted, and went to reinstall windows, but i couldnt even install windows...i still got the error... so i bought a new hard drive... still go the error...then for like 3 days i didnt do anything...came back to it one day... and I installed windows fine………………………….. my advice to you would be to check these 4 things… to try and narrow it down
1)check and make sure you CPU is not overheating
2)make sure you do not have a bad HD
3)make sure your video card isn’t sharing an IRQ with any PCI cards.. (with mine it was my Ethernet card, you can find your IRQ listings in device manager, then VIEW resources by connection…)
4)make sure you GPU isn’t overheating…
