i have a dell 435mt with a ati radeon 4850hd DDR3. my pc has the i7 processor. only when i am online or in a game the screen will all of a sudden get these black and gray slices through the picture, and sometimes black spots and sometimes the whole screen goes black. the PC is only around 3 years old, but i have used it for gaming so i was wondering if this was my video card taking a crap? I changed monitors to eliminate the "monitor going bad problem." if anyone has had this problem or knows what it is please help i would appreciate it.
thanks.
thanks.
