Graphics Cards

[corellon]

Hi people,

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:

• adding a registry entry for TdrDelay as per https://support.microsoft.com/en-us/help/2665946/display-driver-stopped-responding-and-has-recovered...
• clean reinstallation of older versions of the driver, all the way back to 18.5.1 (last time I installed a new driver version that was working fine was on 29 May, but even rolling back to a 23 May driver version didn't help)

Please help!
