Alright, earlier today my MBP running snow leopard began to flicker funny colors and lock up. Now when I restart to turn it on I get the grey screen of death. I have my original install disk and I have tried PRAM reset, pushing C with my disk in to run from CD, pressing alt and run to CD....all get grey screen of death. I have everything backed up on time machine, so I am not worried about formatting my computer, which I guess is what I need to do from reading this guys answer of the apple forums. I just need to know how I can format my hard drive when I can't plug it in to another working mac. Thanks!
