PC keeps rebooting

[Wolf Grossi]

Greetings!

running OpenSUSE's 11-3 Linux firmware test on a PC makes the PC
immediately rebooting.

The pc had WinXP installed and began to reboot while working.

I replaced the disk and tried to install Linux, with the above Problem.


What could cause this problem?
Defect mobo, CPU or BIOS?

Any hints and comments are very much appreciated.

Tnx for reading

So you attempted to install a new OS on a PC that already was
unstable ?

Defect BIOS seems unlikely. Can be anything.
Mobo, CPU, PSU, Ram, overheating,...

Any hints and comments are very much appreciated.

There are 3 (cheap) options to start with:

- Visually check the PC for contamination with dust.
Especially the CPU cooler and surroundings.

- Visually inspect the electrolytic capacitorsk, especially those
around the CPU and near the 20/24 pin PSU plug.

- Use memtest86 to test the ram

No, running firmware test from the install disk.

Forgot to mention that the only component not changed is the CPU.
