Ever since I've installed Windows 7 Ultimate x64 (7100), I've been encountering consistent system crashes whenever the system is stressed, be it by videos or games, for a short while no more than half an hour. I've looked at the crash dumps to try and isolate whatever driver could be the issue, but it seems strange to me, as it wasn't a problem I had with the Windows 7 Beta. Notably, my beta build was x86. Each one of my (so far) 6 'BSoD's have had the following in common: They occur consistently with video and games, so I thought it may be related to my video card (GeForce 8800GTX - 185.85 Win7 x64 drivers), but I haven't been able to find anyone else with a problem with these latest drivers. Does anyone know of a way to find where, specifically, my driver issue is, and how to amend it? At the very least, is there anyone else with this particular issue?
