[Aside - When having a hardware problem, why do people put their hardware
information at the bottom of the message? That's about as bad as top-posting,
IMO. It means we have to skip to the end to learn the config then go back to
the top and re-read... That's just not a good use of anyone's time.]

(In this order, but stop when something works, of course).
Zap the PRAM.
Replace the PRAM Battery.
Disconnect all internal drives, pull all the memory and the video card. See if
that produces at least some error beeps. If it does, then your ps is fine, you
just need to fix whatever the beep said.
Disconnect the power supply and check its voltages... (looks like other replies
have covered that)
Do you need the repair manual?

Sorry for info at bottom. There is no KVM or other ext devices connected. I
listed a 300 GB firewire/usb enclosure but it is disconnected. I corrected
description above.
Yes, I could use the repair manual...thx
