I had this problem a while ago when trying to re-install win 7 64bit ultimate back onto my machine. I trolled the forums and found out that my GTX 295 grafix card needed to be installed using an older graphics driver. Then discovered that the memory on my graphics card was dying so I got a replacement and since then I've had no probs.

What Graphics card are you running andwhat version driver are you using?
