A screen full of messages and computer locks up

[chausx]

My computer will be working normally when suddenly a screen full of messages (errors?) appear and the computer locks up. I have to force shutdown using the power button. This tends to happen between 20 minutes and an hour after the computer starts.

I have Ubuntu 10.10 Server installed on the system, but I also have the same problem using Gentoo liveCD.

Here are the messages I get when it does this:

[< ... >] ? cpu_idle+ ...

[< ... >] ? start_kernel+ ...
[< ... >] ? i386_start_kernel+ ...

I removed the numbers and letters at the beginning and end of each line after the first, but I can get them if needed.

I am not really sure what this is or how to fix it. Any help will be much appreciated.

Since this happens both with the installed Ubuntu server distribution, and a Gentoo LiveCD, then it is probably a hardware failure. You need to get and run diagnostics on the hardware (motherboard, RAM, NICs, etc).
