Hi there

I have recently reformatted my Hard drive and my on my PB and then it refused to boot from any CD be it tech tool or the software restore cds. At the white screen during startup the apple logo appears but then gets slightly skewed and the entire computer freezes. Since I wasn't able to install an OS that way, I started it on target mode and installed an old copy of panther that I had laying around. the installation went fine but when I booted it up, I got a square full of garbled static where the apple would be on the white screen. This confuses me because the computer worked fine before I reformatted it. I have tried zapping the Pram and testing the disk integrity in disk utility and everything came back normal.

Any help would be greatly appreciated.

Try the Apple Hardware Test CD that came with your machine. It can usually detect major hardware problems, which is what it sounds like you're suffering from. Did you also reset the PMU, and try taking out any extra RAM?

Ahh thanks, I'll try the PMU. Also the ahrdware tests.
