[GLLUG] desktop freezing??

[Karl Schuttler]

You can get a decent power supply these days for 30, 40 bucks. Just
throw a little money at the problem and see if it fixes it. If it
turns out to be not the case (gadunst), you'll have a powersupply
handy for when one of the ones you have being used dies in the next
six months.
