XFX HD 6870 DUAL FAN, CRASHING / NOT WORKING PROPERLY.
Hello gentlemen, I need help with my GPU. I bought the HD XFX 6870 a while ago and I can't even use it properly. Whenever I try to play a game on high performance (for example: Dota2 on high/med settings) my screen turns black in a couple mins. After like 2-3 secs it goes back on, but it's just frozen. Then I gotta restart the game by CTRL+ALT+DELETE and when i rejoin the game its laggy as hell. I play at like 5-8fps. Btw, whenever the screen turns black, the ingame sounds keep going. This is for EVERY game I have. I tried playing battlefield 3 on medium but it crashed after 1min, same problem occurs with every single game.
How can I solve this? I mean I paid 150 euros, but this aint worth any!! I tried: Reinstalling drivers, deleting drivers of my old nvidia.
