Any ideas?

I'm certain a bad psu is damaging mem chips and agp slots/cards.

There are power supply testers out there, ranging from the low end, yes it turns on and gives X voltage to light up the led to the more expensive tests everything for a price. I'd honestly just replace the power supply they are cheap enough, and if you suspect it is the power supply/power problem that is something easy to do. I'd also look at a UPS/Power conditioner for that machine to rule out power surge/sag problems.

If you are game, you can put multimeter probes into them. However, they need to be the right ones. Here is a guide for testing one with a mutlimeter:

You need a load for ATX power supplies so they do not burn them selves out during testing. the simple light the light "testers" provide that.

I use this: Apevia PST-03 Power Supply Tester w/LCD (http://www.newegg.com/Product/Product.aspx?Item=N82E16899161001). The reviews say the sata connector is flimsy. I havent had much of a problem with it. You just cant RIP the cables off it like a caveman.
