the -5 and -12 voltages are rarely used these days. Sound cards used to use them to for their power amplifiers back when they had them, and some modems used them similarly.

It is interesting that the smaller power-supply specs omit -5V, as it is used only on old ISA cards.

Anyway, power supplies are a possible cause of instability, as are failed capacitors (remember the capacitor plague of a few years ago?).
