More information would be helpful to answer your question. Is the computer a laptop or a desktop? It really doesn't sound like a bad power supply but the easiest way to tell is try another known good power supply. You should also follow the My PC Won't Start sticky at the top of this forum.

Did the problem start when you upgraded the motherboard? Some newer P4 /AMD Athlon motherboards have an additional 4-pin power connector on the board. If this isn not connected you will not be able to get the computer to work. Even those that don't have the additional connector may require more total wattage than a Pentium 3 system power supply can deliver. I would recommend a power supply that provides at least 400 watts output for a newer system.

It could be a pinched cable or something else internal causing a short when power is applied. Another possibility is a defective voltage regulator chip on the motherboard or a chip that has a bad solder connection. Those problems are a harder to find and fix without some good tools and electronic troubleshooting experience. There are a couple of shops that advertise they do board level repairs on laptops but you have to ship it to them for an estimate and then decide if the laptop is worth the cost of the repairs.
