Quantify several...
I have photos (see below), but I personally have not been to the genius bar. However it sounds like the original poster has, but without resolution.

Erasing the hard drive and reinstalling will not help if it's a software problem related to safari, flash, and graphic switching (ie. snow leopard). Safari, flash, and obviously snow leopard are by default installed on the computer. Therefore, the problem will occur again.
My point is that I do not want to go through the hassle of getting my computer's hardware "repaired", just for the problem to re-occur due to Apple software problems.
