Your motherboard is dead, but the one last thing you can try is to put
the p4 1.8 in the motherboard and see if it'll boot (it probably won't,
but it won't hurt the chip) . It's suffering the typical black and
silver emachines death of simulltaneous motherboard and PSU failure.
I've seen more than a dozen of these. The CPU, hard drive, RAM, and
optical drives are still fine, probably. It's nothing you or the
previous owner did to kill it, it's just emachines.

A standard mATX motherboard will fit in that case.
