I've been having this issue since i've upgraded my GPU from a Sapphire HD6950 2GB to a MSI HD7950 3GB. It happens at random moments, even during simple internet browsing.
I've read about people with the same problem but also having artifacts (some even in windows) but the only problem i have is the display driver stopping and recovering turning my screen black for about 2 seconds. But no artifacts.
My temps are fine, 35 celsius when idle and about 70-75 under load.
I'm currently using the 13.3 beta driver, as i had hoped it would fix my problem, but i've had the problem with 13.1 as well.
I've run Prime95 and Msi's Kombustor (2.5) and memtest (from a bootable usb stick) to see if it might've been a hardware problem, but all tests show no problem.
I'm using Norton Internet Security 2013 with the latest updates so i'm 99% sure there are no virusses or spyware on my pc.
The pc i'm having the problem with is equipped with the following:
Intel i7 3820 @ stock (3.6ghz)
Gigabyte X79-UP4 (Latest stable bios)
MSI HD7950 3GB
4x4GB Corsair Vengeance DDR3 @ 1600mhz
OCZ ModXStream-Pro 700W (I know it's overkill but i bought it in case i'd ever want to go with 2 gpu's and it was cheaper than the 500 or 600W versions)
Crucial M4 128GB ssd as boot disk and 3 WD HDDs, a 640GB, a 1TB and a 2TB HDD.
Windows 7 64-bit with all the latest updates and service packs
Really hoping someone here can help me solve this issue..
