Hey guys, everytime i either play bf3 or dirt 3, i get a weird crash. I get a black screen and then kind of flickering at the top of the black screen. Heres my specs:
AMD Phenom II X6 @ 4GHz (fully stable)
Asus Crosshair V Formula
Corsair XMS3 2 x 4GB
2x AMD Radeon HD 6950's
And last not least an OCZ ZX1250w PSU!
thanks for any help

I would bet on a stability problem. Set everything back to default and see if it occurs. I havseen a few of these where the power supply is marginal. You really have to trouble shoot the whole system to find these odd shut downs.

For the sake of stability, revert the CPU to it's default (aka don't overclock it) and try playing with just one Radeon HD6950.

See what happens with those changes and post your results.

I had a graphics card a few years ago that did the same thing.

CPU was fine, power supply was fine, eventually swapped cards with someone else and the crashing went away.

I did two things to fix my issue.
1) I flashed (I think that's what it's called) my graphics card and updated to the newest firmware.
2) I removed the fan/heatsink from the graphics card, put more thermal compound on it and put the fan/heatsink back.

Do step 2 first this with the card you were originally having issues with. If it works fine then do the same with the second card.

When you flash cards, make sure they are both on the same bios.

Theire both from different vendors, Club3D and XFX, so flashing will be difficult and i dont want that as an option. As for the thermals on the cards, i monitor them all the time with msi afterburner, they both run on mid 70's on full load. They arent overclocked either.

Then I would remove one card and change the CPU to it's original clock speed.

A single unstable card could be causing these types of failures.

You seem to be doing a good job of monitoring and trying some of the suggestions I and others have made.

I've defaulted my cpu, but now I got a different problem. I uninstalled ALL the catalyst drivers, including USB 2, I am stuck with a PS2 keyboard since no usb device is recognised, and also It doesn't let me re-install the drivers for the usb. I've tried everything, deleted all amd folders ect, used drive sweeper. Still with no sign of anything working. I'd appreciate if anyone can help me, this is killing me right now!

Hit start (windows button) type "cmd," right click, hit run as administrator and type "sfc /scannow"

This is a windows file system checker. Let it run it's course.
Second, download the following pieces of software and run them in this order:
rkill,
tdsskiller,
malware bytes,
combo fix,
ccleaner (first run the system cleanup, then registry... make a backup of your registry.)

I usually don't recommend registry cleanups because those are double edged swords... but you have something else bad.

Also you could default your bios settings back to what they were when they left the manufacturer. That will help with anything left over from the second graphics card and overclocking... Don't do this unless everything else fails.
