AMD Radeon HD 6990 graphics problems

[alexkemple]

So, I recently got an AMD Radeon HD 6990 with 4GB of memory designed by Diamond Enterprises. I now have graphics issue with my computer when attempting to run games, such as Battlefield 3 in the images. The screen turns to lines and eventually blue screens. This does;t happen with HD video, although it does get jumpy and glitchy. I have the Radeon on an MSI Z68A-G43 B3 MOBO, with 16.38 GB of RAM, and an Intel Core i5 3.30GHz processor running Windows 7 64-bit. Temperatures are NOT hot whatsoever, so the problem isn't overheating. I have tried re-installing drivers, trying different drivers, adjusting resolution, checking if it works with individual RAM sticks, and moving the card to a different PCI slot, nothing has worked.

does anyone know what to do?

thanks

This is with it running normally

And with it in the process of crashing

And Blue Screen

I just tried running BF3 again and got this

Ive tried reinstalling drivers, but am not sure that I am successful. How would I go about doing a full re-install?

Well... I used a Driver Sweeper to remove the previous GPU drivers and reinstalled using the Diamond provided CD, which has the latest drivers since the GPU is pretty new, and it got MUCH worse... see the photo...
The display is so poor that you can't navigate the computer period...

Nice! [:russwood1488:5]

edit: by the way, did you by chance use "Driver Cleaner"? If so, don't. I got a full copy of it from Sapphire and used it one time and it wreaked havok on my machine... it definately cleaned house! not good.
