[dba-Tech] Digital Senility

[Arthur Fuller]

I have an old HP Millenium Edition tower (AMD-64, 5GB RAM, that is near and
dear to me because she's served me well for years and years. But of late
something's gone amiss. It boots up normally but after a while it just
arbitrarily powers down. Even more strangely, occasionally while in that
powered-down state it powers up, all on its own.

I'm guessing that it might be the power supply, but what I know about
hardware wouldn't fill a thimble. I hardly ever use this computer, since my
laptop is way more powerful. I don't want to spend a lot of money fixing
the problem, given current prices for a refurbished computer, but if only
for romantic/historical reasons, I'd like to keep her operational.

Does this symptom sound like a power supply problem? If not, any idea what
might be wrong?
