So heres what happened. I just updated my drivers and restarted my computer(no problems with that). I then started to play planetside 2 or garrys mod for 30 minutes ( i forgot which one ) . I exited the game and the windows taskbar was white. The taskbar turned back to normal after I launched black ops 2 and I closed it. What does that mean? My guess is that it could be my GPU ( gtx 660 ti SC). It could also be the drivers i have 310.64. My GPU temp at the time was around 50-60 Celsius. Please help.
