If it's not a silly question:
1. How did you many to reflash the BIOS if the machine won't boot? (unless you're lucky enough to have an EPROM burner!)
2. How did you manage to "vary" the position of the power connector on the motherboard? It's designed as to only be able to be fitted in the correct socket.
3. If it's a new P4 motherboard, I'm surprised it has it only got the old single power connector. Does it have the two newer power connectors as well - and what does the power supply have?
4. What, exactly, is the motherboard model?
The voltage means nothing on it's own. You need the full figures. See
here
p.s. If you've been sticking a live power lead, at random, over pins connectors I would consider it as almost absolutely certain you've blown it - and it's got nothing to do with
static electricity!!
Try taking both the board and power supply out of the case, connecting them, and then short across the power on pins with a screwdriver. If the power supply starts it's probably a wiring/earth fault. If not, you've probably fried it. Hopefully the CPU and memory will be OK, but you might have fried them as well. Keep your fingers crossed!!
