Computer freezes

[GyroFX]

Hi, I'm on a Powerbook G4 1.6Ghz with 1.5 GIG ram.

Every so often, My computer would have that grey stuff scroll over and the computer freezes. I'd have to restart and I get this message in the Problem report...

Is this a software issues or hardware?..considering it's talking about the CPU. Will re-installing the OS help at all? Please help.


thank you

It's most likely a hardware issue. Do you have any third party hardware installed? Have you tried testing your RAM by removing a chip at a time and checking if it still kernel panics?

Reformat your computer, or simply downgrade your updates.

I wouldn't be that hasty! You can start out by just unplugging some USB or firewire devices and that may fix the problem. It could also be a RAM issue.

EDIT: This is a good article about kernel panics: http://www.thexlab.com/faqs/kernelpanics.html

Why the thread revival? If it's a hardware issue, a reinstall will never help.

I assume you have nothing connected to your Powerbook? Best bet it is RAM or HD. Is all software updated?

Good point! i never noticed the dates....
