2 days ago i played some dota 2 and after 2 normal games my dota 2 crashed. I got black screen, then i was in windows and at top left corner i have a windows that said dota2.exe and i cant see any visuals of game only the little top bar of program. I was trying to install latest drivers nothing,then i tried furmark, which had artifacts. I tried old drivers, it worked only on furmark, not for game, game was crashing after picking a hero before game have something visual. Now im on reinstalled windows 10 and im on the old drivers, still have same problem. Games doesnt load visuals- dota2 GTA V (DX error) arma 3 (artifacts till it crash). I tried CS GO and it was running fine at 200 FPS without artifacts and crashes. Its only game that work normaly. What i should do ?
One guy suggested me the oven method, but i dont have oven at the moment. I tried switching 6pin cabeles nothing. what else i can do ? maybe reapply thermal paste on GPU ?
sapphire r9 270non-x dual X 2G version (max temp that GPU has while playing dota was about 63°C - opened riva tuner with HWinfo while playing)
AMD 6300 @3,8GHz
8GB RAM 1600 MHz
