spontaneous reboot

[Darryl]

Greetings,
I have a P4 machine with Intel mobo and kingston memory. It has
been running nice for over a year. No problems or abnormal behavior.

Recently, I had to strip it down and re-install Win2000 on it (for another
user to use). It has been working fine for over two weeks. Today,
it started spontaneous reboots. It will be setting at the desktop, then
poof. Start rebooting. I shut it off for over an hour (while at lunch).
Powered it up, and after sitting at the desktop for a few minutes
(5 or 10) poof. reboot.

What can be causing this behavior? What should I start looking at
first ?

thanks,
Darryl

Right click mycomputer/select properties/advanced/startup and
recovery/
uncheck "Automatically Reboot'. You should then start seeing error
messages, which may provide clues as to what is failing.
Also, you can check the log files, which are listed immediately
below, for any information.

Already did that. It still reboots and there are no messages.

it could be the power supply connector
possibly loose, tarnished or burned

Do the log files say anything useful?
