Have you tried to disable the USB controler in the BIOS?  I (and
others if you search the lists) have had problems with Dell PE
1850/2850's if the USB controller was enabled which caused hangs as
soon as there was a moderate ammount of disc IO.

I can't recall what the earlier threads on the topic came up with as
the cause for this, but I seem to recall it was related to interrupts.

Could be related to what you are seeing, or maybe not.
