Hi, My girlfriend's Macbook gave her the restart computer, kernal panic message earlier today when she tried to open a .tiff file in Photoshop CS3. She did as she was told, however now the computer won't get past the apple logo when we hit the power button. Every time the message comes up. I have had a look around the net and tried the advice I could find, but haven't had any luck. I have tried resetting pram and the other one. I have also taken out each memory one at a time to see if this makes a difference, but each time the message still appears. She has a 2007 Macbook Pro running Snow Leopard, which we upgraded around a month ago from Tiger. It's got 2gb of ram and I think 2.2Ghz Intel Core Duo Processor. I would really appreciate any help on what else could be up with it? We can't find her Apple Hardware Test cd either. Thanks very much for your time.
