Hi. I have this problem with many games. These black squares appear in some games for a very little time. I want to know what's causing them? and how to fix it. is it a faulty graphics card?
View this video and watch in fullscreen. These squares mainly happen when there's sky visible. (other areas are clean)
Oh, i forgot the PC specs. here:
Windows Vista Home Basic 32-bit SP2 (Updated always)
Club3d HD4850 Factory OC 512mb (upgraded from 8600GT months ago)
Core 2 Duo e4500 @2.20GHz
3GB ram (1x 1GB, 1x 2GB) (upgraded from 2x1GB)
