New Gigabyte 6850 causing BSOD

[mmntech]

SOLVED : Apparently ATI Tray Tools is incompatible with these cards.

I had bought a Gigabyte HD 6850 over the holidays. I get it home, plug it in, works for about five minutes, then the system blue screens. I spent The whole day ripping the system apart to localize the cause of the crash and it's definitely the graphics card. It must be faulty. My old Sapphire 5770 works just fine.

Drivers were a clean install. Deleted the old ones then ran DriverSweeper in safe mode.

So today I returned it to the store and exchanged it for a new one. So I put the new one in, same thing. Works for a couple minutes and blue screens. I suppose it's possible that I've gotten two bum cards from a bad batch. But I wonder if its something else. This is a head scratcher. An ideas? System specs below.

It's this card...

AMD Phenom II X4 855 BE at stock (also tried it with my old X3 710)
8gb DDR2 1066 (all tested, works fine)
Antec Earthwatts 750w (brand new, tested, works fine)
Catalyst 12.1 preview, also tried the latest official drivers, same thing

Could be that motherboard has problems with the 6000's series for some odd reason. Checking the bios for that mb hasn't been updated for awhile. I'm guessing your old video worked fine with your system.
