I just recently bought an eVGA GeForce 8800GTS 320MB to replace my GeForce 6800, but I'm having trouble booting into Vista. When I try and boot normally, I receive artifacts on my screen. I thought this was a driver problem and could be fixed by going into Safe Mode. However, when I try and boot into Safe Mode, all I receive is a blank screen, or sometimes, a screen filled with a bunch of artifacts. I'm running on an ASUS P5LD2 motherboard, and I have tried several different BIOS versions but they all render the same result.
Here is a video I just recorded of the issue. Please excuse the poor quality, its from my phone:
