Similar issue here, I've had the IRQL BOSD, amongst another half dozen.
Got Win 7 a couple days ago along with a Nvidia 260gtx. Installed Win 7, got that up and running then put the vid card in, everything was dandy. Updated all the drivers to Win 7 when available and installed my basic programs (word processing, web browsers, etc). Then the other day I was playing Arkham Asylum, and my comp froze. Did a forced restart and then everything went to hell. I can no longer access windows 7 or xp, everytime i try to run a disk check it restarts, ditto with the win 7 memory diagnostic, I moved the vid card to the other PCI express slot farthest from the chipset, moved the hdds to get better air flow and been running with the case open thinking it may have been heating issues, didn't work. Then i started removing ram dimms one at a time and testing thosem no dice so i bought 2 new dimms, still no go. For a brief time i was able to get win 7 to work for a few min at a time, but a few min later comps would restart, i was able to kinda fix it by using the system restore but that no longer works. I have also reformatted the windows drive and tried to reinstall XP and Win 7, neither works. Win XP partially installs but reboots, win 7 partially installs but then something weird happens and it wont boot. Tried booting in safe mode, but it get to loding the classpnp file and just stops.
System:
Athlon 64 x2 5600 2.8ghz
MSI k9n4 sli-f am2 nforce 500sli
600w PS
geforce gtx 260 core 216 896mb
80gb sata 7200rpm (OS HDD)
Kingston 4gb ddr2 667mhz (4 DIMMs)
I think some of the fixes given earlier would work, but since I can't actually get into windows, even in safe mode, i can't try any of them. Gotten a bunch of BSODs through the whole process, copied down all the error messages, but i can't find most of them online, and those that i can find can only be resolved by actually having access to the desktop., which i don't have.
New development!!!: I cannot even boot from the win 7 or xp disks!!!!!!
Anything that I can try would be helpful.
