PC shuts down by itself & reboots

[Guest]

Hi,

I have a brand new PC which has Microsoft XP installed. It keeps shutting
and rebooting on its own while I am in the middle of doing somthing. I
thought it was the power supply which was replaced. The BIOS and Windows
were also updated. I am loosing patience with this PC and my options are
running low. Anyone has any idea what could be wrong?

Press Windows key with Pause/Break key to open System Properties, click
Advanced tab, Startup and Recovery "Settings" button, deselect System
failure "Automatically restart". Then you will see error messages and
can continue from there.
