What happened ?

[Nat Sass]

mb: asus p4p800-e deluxe
uP: P4 2.4 ghz, 800mhz fsb, 512k internal
no overclocking going on.
PC idling on desktop, I plugin an older Intel Netcam to install drivers, and notice
the pc is locked up. I press the reset button. PC doesnt post, but begins power
cycling off, then back on, off then back on, off, on and I turn off the psu at the
rear of the case.
I remove/disconnect all but ram, video card, mouse & keybd and speakers. Apply power
and Asus AI post reporter announces "System failed cpu test", over & over.
So I cannot connect any dots between usb device & uP failure. The only common
component is the mobo. I would like to hear some ideas as to what you all think
happened. Was the P4 sensing some malfunction of the power supply and shutting on
down ?
Right now I dont trust either the mobo or the uP. Thanks in advance for your
thoughts.

Scott,
The uP has failed and the board cannot be booted to obtain usb settings.

(note: Asus AI reporter does not require the mobo to be booted)

It could be anything - but it's most likely the Motherboard. Could also be
the PSU, so I'd swap that before anything else.

The only way to be certain, is to try different RAM/CPU/Video in your board.
