I have a 15" MacBook Pro early 2010 with a 320GB HD and 4GB of memory. It was acting up so I though I would do a re-install and see if that cleared it up. Well I put in the re-install cd and got the "you need to restart your computer" message. I tried booting from the cd, starting in safe mode, remote install, and everything else I could find on the internet and needless to say nothing worked. So I took the hard drive out, put it in an enclosure and tried to reformat it on my gf's pc. Well now when I put it back in it wont register the hard drive and it still gives me the "restart" screen. I am lost at this point and have no idea where to go from here. Please Help!!
