I bet you (a virutal non-monetary sum) that it's Matt's option #5: "poor
quality supplies".
There are a lot of bad power supplies and / or mobo voltage regulators out
there. If you're at all interested in seeing how to fix them, there are a
number of resources out there like this:
http://www.badcaps.net/
See the "how to identify" section. Many times a bad cap isn't completely
blown. It may be "domed". I've seen them where the top looks fine, but the
bottom is bulging, causing the cap to sit crooked on the board.
Messing with a power supply isn't for the meek. It's potentially
dangerous. You can get a decent replacement power supply for $40 or $50
(for instance, Office Max carries Antec Basiq power supplies, I can walk 2
blocks and pick one up, very handy for me).
If it's a bad cap in the voltage regulator on the mobo, that's a harder
fix. It can be done, but you have to use care when desoldering / soldering
caps on a complex circut board like that.
