You made sure that the heatsyncs where properly attached whenever you attempted to fire up the units? , correct?
If not time to buy some cpus.
All I can say is try resetting the cmos, check your cables and jumpers (if any) and set the boards to the lowest FSB, preferably 200mhz, ditto on ram if you have jumpers for it.
I have several boards here that will refuse to work after being touched, then I mess around with them (remove, ram/video) and they start working again. (probably microfractures or cold solder joints)
If you want to see if the boards live at all, remove the ram and the video card and fire up one of the units with the speaker attached, if any of the boards logic is working it should beep at you, meaning that something else is going on here.
Good Luck
