Almost everytime I run a program, it varies as to what it is, but for instance I just installed ATI tray tools and when I ran it the screen went black for about 1 second then went normal again (with it running) It doesn't seem to be hurting anything, but is this normal? I recently upgraded to an x1900xtx, a a8n-32 sli deluxe mobo, and a 4400+ amd 64 x2 proc.
