Hey, I got the new 20" iMac a few weeks ago, but have recently been having some problems. Programs that never crash on any of my Macs have started to crash on my iMac like iTunes, PS, AI, Safari. I did a repair disk on the hard drive and it found some problems and corrected it. But then a few days later it started giving me problems again like it would freeze all of a sudden and I would have to pull the plug. So I had to repair disk again. The attached pic is what shows up. Any help appreciated.
