Hi, My Ps3 won't boot past the welcome screen (that says SONY COMPUTER ENTERTAINMENT). I can hear a noticable stutter in the musical bit that plays, then the writing dissapears and I am left with that swirling line - and no log in names appear. It just hangs like that. It won't turn off from holding down the button, instead I have to flick the power switch at the back. I am using a 250gb drive I put in, so I tried the old 60gb one I got with the machine. It boots up fine. So its the drive not the machine. the 250gb drive has been running fine for months, until I got PLAY TV that is. It froze twice on the boot up since I've been using Play TV. Has anyone got any ideas of what I can do? I don't think I can reinstall the drive if it is not recognised?
