[ale] OT - hardware problem

[jknapka at kneuro.net (Joe Knapka)]

Hi everyone,

I'm trying to diagnose a problem with a friend's machine.  It powers
off randomly, usually early in the XP boot process, but usually after
the "Windows XP" cylon-eye load screen is running. I tried running an
Ubuntu live CD on it, and it booted all the way to the desktop and let
me surf the web for about 10 minutes, then spontaneously powered down.

Aha, thinks I, it's probably a power-supply problem. So I replaced the
PS, but the behavior did not change.

It is likely to be a motherboard issue?  Or is there other stuff I
ought to check first?

Thanks,

-- JK
