MacBook Pro won't boot, says to restart
I have a MacBook Pro purchased March 2007 (the original dual processor, I believe. My OS is Snow Leopard. Probably with the latest updates but I'm not certain since I can't check it. When I attempt to start it up I end up with a dark grey screen and I box telling me, in several, languages, that I need to restart my computer. However, restarting leads to the same thing. I booted using the install disc and used disc repair but it said the disc is fine. Any suggestions for how to start my computer? Thanks.
MacBook Pro 15", Mac OS X (10.6.6)
