I am getting THIS error whenever I boot up my mac. I believe it is called a "Kernel Panic". Before this happened my mac kept freezing randomly. When it locked up the screen flashed and displayed purplish colors. It would usually just restart, but it won't now. I went to the Genius bar and the guy was pretty much helpless. He told me to insert my Snow Leopard disc and reinstall it. Now just an FYI, I already restored using the original OSX disc that came with my mac. I erased the HDD and it worked for a while, but then it froze up again after a few days. I told him this and he said to use my SL disc and do an archive install. I inserted it and it won't load up. I held "C" down when my computer started and I still get that same error message, and now I can't eject the disc. He said if this doesn't work then it's most likely a costly problem. I've researched quite a bit online and can't find a solution. I'd appreciate any help I can get! Thanks for your time!
