I am hoping that there is someone out there that knows lots about GPUs because i seem to be having a major issue with mine. So i was in the middle of a dota game and all of the sudden my windows decides to default back to the 98 basic theme, aero off and all that fun stuff, so I think whatever ill deal with it after. But once this happens I start to get odd flashing and artifacting on my other monitor where i have twitch and music open and such. This is not on both the dota game is fine no FPS loss at all nothing but on the other one its being all weird, so at this point I tab out to see if I can figure this shit out. Go online and download the windows aero fixer, run it and it says that my GPU cannot run DX9 or higher and there is no pixel shader model 2.0 either. I know for a fact that is is not right because i have been running aero since day 1 and there is no way a GTX670 doesn't have any of that. So I go and restart and instead of booting in a normal time windows boots in the usual time but for the actual GUI of windows to come up it takes a good 2 or so fill min before anything comes up, before that its just a black screen.
So im thinking my card is on its way out but anytime i run a benchmark or anything else to see what the fuck is up with it nothing comes up, no artifacts, no CTDs, NO BSOD, like there should be if there was a real problem with it. So I got no idea whats up and would love if someone could shed some light onto this because its not making any sense to me at all.

The card is a EVGA GTX 670 FTW aswell.
