Take a close look at the capacitors on the motherboard. If they are bulging you can either replace them or the whole board. Walt

This points more to a low level hardware issue in the motherboard, or possibly the CPU. Hard to know. If it's old enough, it might be time to just replace it.
Just wanted to follow up with the group on the final resolution of this issue (I hope!). As I wrote earlier the new power supply didn't help. I ended up buying a new motherboard, got it today, installed it tonight with the old power supply and all came right up w/o issues. Interesting findings: when I took the CPU cooler off there was a big dead spider curled up amongst the power inductors surrounding the CPU. Also, there were a couple caps that were slightly "crowning", i.e. bulging a bit on top, when compared with some other identical ones on the board with the same capacity. So I figure either of these could be contributors, more likely the caps. Now I have a nearly brand new Antec 450W power supply back in the box, for sale if anyone's interested. Thanks all for the help, Brett
