Perhaps someone here has had something similar in the past ?

USB failures and consequential southbridge failures were a common problem
with some steppings of the i865 and i875, IIRC. I don't know if that's
your problem here.

Yes, ISTR the similar P4C800 mobo was particularly prone to (what was
assumed to be) static entering by way of a USB port and damaging the
SouthBridge, so maybe here, too.
There are/were some impressive pictures of burnt SB chips on the web.
Here's a link describing the 2 main failure modes (for the P4C800):

in case it helps OP.

Cheers,


Thanks for that guys , I'll tell him he's lucky he's still got a
working computer at all and point him in the direction of a USB PCI
card
