Or it could be capacitor(s) starting to dye.
You'll know about that because after a while (hours, days or months) the
machine will become unusable and eventually will fail the POST and won't
boot at all. I've found the most common time for this to happen is
summer time, probably because of the increased operating temperature.

Faulty caps are easily spotted (a bulging or a browny colour on the top
of the cap can) and apparently easy enough to replace but I have yet to
repair a motherboard myself.
