Yesterday I noticed my computer crashing and restarting when playing 3d games. This happened twice, but it worked for a few hours while I was playing Team Fortress 2. I thought this may have been a driver problem, so I rolled back to the earliest driver I had, but the problem persists. Now I am getting BSODs, and one was right on windows launch. This is looking more like my GPU is forgeted up, and I need to know if it is. Everything except 3d games are working perfectly (most of the time), so I was wondering if it is or isn't a hardware problem. All advice would be appreciated.
