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. -- Simon L. Nielsen
