Hello. I have a Gigabyte HD 7850 OC 2GB (GV-R785OC-2GD).

When i play games,it freezes with black screen and sound loop.

Tested with FurMark two times 1080p 15min,no errors,freezing happens in games.

My cards Core clock is 975mhz and Memory clock is 1200mhz.

My system. Parts are new.

CPU - Intel Core i3 3220 Ivy Bridge Stock Cooler

MB - MSI Z77A-G43

RAM - Kingston HyperX 8GB Kit of 2   XMP - On

HDD - WD Caviar Green 500GB Sata3

PSU - Fortron Hexa 500W (Peak Power 550W)

OS - Windows 7 Ultimate x64

Catalyst 12.8 (instaled earlier versions,the same happens)

So any ideas what is this? If someone can help,that would be fantastic.

P.S. Now will Reinstall My Windows to fully erease all drivers,because can't delete amd display driver. Then Instal new 12.10 and see what it gonna say.

So today i was testing Battlefield 3 on my clean system.

Catalyst 12.10 - freezing with grey screen with vertical lines.

Catalyst 12.11beta4 - monitor says "No Signal" no sound of the game and no reactions to Alt+F4,Ctrl+Alt+Del,Esc and etc.

Need For Speed Shift and Shift 2 Unleashed - runs normaly,but have some flickering\artifacts with 12.10 and 12.11beta4 drivers.
