x64 Windows Ultimate 7 Service Pack 1 retail
Hardware is maximum 2 weeks old.
Tried with windows 7 32 and 64 and xp. Crashes in most.

Comes whenever i use computer "random" and more when i play battlefield bad company 2,,

Ive tried using the latest 11.2 catalyst drivers from ati.com among the olders there.
And the drivers from the graphicscard driver-cd. i get same error.

It usually starts out fine with newly installed drivers, but when it freezes for the first time it gets more freezes...

Faulty card? Could i run som tests on the graphic card?
powercolor radeon hd 6850..

- Boot into Safe Mode with Networking
- Uninstall the Display Drivers including Catalyst Control Center
- Use Driver Sweeper to sweep the traces of the driver Guru3D - Driver Sweeper
- Install the latest version ATI Radeon
- Reboot into Normal Mode

I looked at temperature when playing bad company 2, it goes to 64-65 celsius. and the fan is running at 65%, so i dont believe its a heating problem..

Allready did that a zillion times DeanP, it doesnt seem to work..

im gonna try returning the card / and/or have someone professional to look at it.

I will come back with my soloution, if i find any ^^ (RMA or highly qualified computer repairing pro's)

thanks for all help so far, highly apreciated :)
