HiThis may not help you but I recently had exactly the same issue. My system is an win XP SP2 on Asrock 880GM-LE mb, AMD Phenom 965 cpu, 4g ram and a Radeon 5770 graphics card. I was having issues in FSX corruption of the images on my 3 monitors after I had upgraded FTX Australia from SP3 to SP4. I then upgraded the CCC drivers to 11.2 and this did not help.Fortunately I always make images of my C drive, where I have the OS only, and restored an earlier version of the OS. I have not had the problem since. I was dreading going through the hw route of trying to work out if it was a PSU, GPU. MB or whatever.Hope you can figure it out
