I recently purchased Windows 7. Everything installed successfully, except for my video driver
for my MSI nVidia 9800 GX2 card. I saw two exclamation marks next to two adaptors that appeared under Device Manager > Display. I installed the latest drivers
from nVidia and I received the BSOD:
Driver irql not less or equal
If I use the Vista-64bit video driver that came with my MSI Video Card CD (dated Jan-2008) the driver works perfectly and no issues with Win 7. However, some of the newer games crash and I receive "driver recovery" errors.
My system is setup for Dual-boot for Win XP and Win 7. When I boot into Windows XP, everything works perfectly using the latest drivers from nVidia, so I am confused why I am having a hard time with Windows 7.
I have performed Memtest, reseated RAM and the Video Card, nothing is overheating. I have tried reinstalling several times with all my USB devices disconnected, except for keyboard and mouse. To no avail, I cannot determine if I have a video card issue, other hardware issue, or if this is a Windows 7 compatibility issue.
Any suggestions would be greatly appreciated.
I have been working on this since Windows 7 was released and cannot figure this out for the life of me.
