I have an iMac 24" 2.8ghz that won't boot up. The DVD drive and hard drive are tested to work, and I can get to the boot menu and select either to boot from. However after choosing either option the computer hangs and often displays a blank screen with only the mouse moving or a white screen with grey dots (like the apple logo exploded horizontally across the screen). I took a pic for reference

Has anyone seen this before? Could this be a video card failure, or something else?
