I'm occasionally experiencing picture corruption in the form of patches of green and red dots while watching videos (after skipping the video to be precise), and immediately a hard-lock. PC becomes non-responsive and I'm forced to do a hard reset. A few points: 1. I've had my current hardware setup for a few months now, and this problem started just a few days ago. 2. Games run fine. I haven't seen any graphical corruption or faced a hard-lock. 3. I ran OCCT on GPU for 20 min and it was fine. 4. I don't use DXVA acceleration for videos. 5. One time I experienced this issue in IE9. Picture corruption was the same but no hard-lock. Windows simply terminated the driver. Is my card or other component dying? If so and it's a hardware problem, then how come games and OCCT are fine? Could it be a driver issue? I installed it about a month ago and had no problems until a few days ago, as I mentioned. Can a driver that worked fine for some time, become corrupted later on? I un-installed and re-installed the driver to see if it changes anything. Will report back. Windows 7 64-bit SP1, fully updated Driver 296.10 EDIT: Re-installing 296.10 didn't help. It somehow made it even worse. Un-installed it and then installed 295.73. Let's see if it changes anything.
