Strange issue with Radeon 6970

[kalius]

Hi all,

I'm experiencing a strange issue with this video card: GYGABITE RADEON HD 6970 CORE 880MHZ MEMORY GDDR5 5500MHZ 2GB 2XDVI HDMI 2XDISPLAYPORT  Model GV-R697OC-2GD with F3 bios

The problem occurs in all the games (BF3,CallofDuty MW3, Total War series, Skyrim).

this is what happens:

When i bought the new pc (about 1 year ago) i never had this problem for two months...

I've tried almost everithing: all driver revision (now I'm using the last one but the problem still persist) Windows 7 and 8.

No overclock.

This are my specs:

Intel Sandy Bridge core i7 2600k.

8gb ram ddr3

Asrock p67extreme4 with latest bios revision.

Mi monitor is samsung synchmaster 2370 with HDMI cable connection.



Any suggestion? Is the radeon broken? I can change some option to try to solve this issue ?

Thank you!
