Did you reset the bios to defaults? Pull the battery out for a minute or two then reinsert it and restart your computer. Sounds like a corrupted bios.

Can you even get into bios? If you can, reset it to default settings.

It's possible your power supply monitor circuitry has failed.

Sounds like the part of your motherboard that monitors the voltages isn't working. If the all those voltages really were zero, your system wouldn't power on.
The fact that you've already replaced the psu would suggest that the psu isn't the problem, so if the system lets you boot, you're probably ok to carry on using it as it is.

You didn't say if this was a laptop or desktop. If it's a desktop, unload everything except the vid card, one stick of ram, the CPU, mouse, keyboard... then try powering up again and try getting into bios. It might be some peripheral loading one of the powerforms down.

By the way, is your bios chip replaceable? You might want to contact the motherboard manufacture and see if you can purchase a new bios chip. Should run anywhere from $6 to $15... much cheaper than buying a new motherboard.
