This one's for all you PSU gurus.
I've got an AT PSU that I use in a test bed. Occasionaly I put a card in a slot and the PSU shuts down immediately after power up. I think the card has a bad cap that shorts the 12v line to ground. So I see why the PSU immediately shuts down. But after several minutes it always comes back to life when I turn it back on after having removed the suspect card from the slot. The last time this happened was the last time the PSU worked. After that there was nothing. I've tried it with various loads and it's just DEAD. Any ideas where to look for the problem? I've inspected the PSU's components visually but that's as far as I've gone. What should I do next?
