I've tried the restart it and tried both with hdmi and the red/yellow/white cord but whenever I turn it on the ps3 says it has corrupted files. When I choose to restore, it restores properly. But after that bar reaches 100 percent the screen turns black. During the post restore black screen, I try to power the PS3 off, but it won't power off. What is the problem here? Do I have a dead hard drive?
