About two months ago I started getting an Atikmpag.sys "VIDEO_TDR_ERROR" BSOD every few days. It never happens when I use the most demanding videogames, only when I'm browsing the internet, or open a game with low GPU usage. It seems to be getting more frequent, at first it was maybe twice a week, nowadays every day, and today for the first time it already crashed twice in an hour.
What I tried in the past weeks without success:
OS: Win 7 Pro S1 x64
CPU: Intel Core i5-2500
Motherboard: Gigabyte GA-PH67A-UD3-B3
Memory: CORSAIR DDR3 1333MHZ 8GB
GPU: AMD Radeon R7 370 (Asus Strix-R7370-DC2OC-2GD5)
