Viewing data for Flickering display

Comments: My screen (iMac 27") is fine UNTIL I go into a more graphics intense process. If I go into PhotoBooth, turn on some effects .. then BAM, there go the flickers. Flickers (plus screen going black intermittently) continue until restart, even if I quit

Specs: 27" 3.06 Core2Duo 1TB
