Oookay. First off. Describe your problem more. Secondly, let us know what you want. Thirdly, tell us your system specs. I know, you have them in your sig, but still.
It appears to be a RAM or driver related issue. This can also happen with a defective GPU. First, I would run your computer with 1 stick of ram at a time. Run memtest as well. Update all your drivers. Then, if the problem persists, try a different video card. If you STILL have the problem, let us know.
