Can a USB Surge Kill a motherboard?

Specs: Windows XP, 1GB
I have two dell dimension 2400 CPUs. An employee brought in a HP 1610 All-in-one USB Printer. They said when they plugged it in, there was a pop and the CPU just dropped. now the CPU does not power up at all. I disconnected the USB cable and still can not get it to power up at all.

I have a spare Dell 2400, so I exchanged the Power Supply, It still will not power up. So I moved the Good Power Supply and Hard Drive to the Spare CPU. Powered it up just fine. Hokked it up at their desk. they plugged in the HP 1610 and POP. Spare CPU will not power up at all.

So did this external USB Printer just kill both motherboards?

i would say yes, it is possible. USB transmits power as well as data, and if there is a problem with the cable or the printer, it could short your PSU, which could cause damage to the rest of your components.

if you're not getting any beep codes, it could be the motherboard, CPU, or both.

with USB inkjet printers costing less than $100, though, i think frying 2 PCs is enough test cases to de-commission that USB printer you've got...

I do not get any Beep Codes, no lights even flicker. Opening up the tower unit shows a green light lite on the Motherboard. If I hit the Power Button, it does nothing, no lights, no fan, no beeps
