The power supply will kick up when disconnected but will not run as it is not connected to the M/B so not getting a power good signal. The likely problem is a memory failure. If you have 2 Simms then remove them and re-insert one at a time and see if it boots up. That will identify a faulty Ram. It may be a hard drive issue so disconnecting that and any peripherals from the motherboard and starting with only the board connected with ram inserted will point to a peripheral problem. A process of elimination is what is required by testing each individual item. You have already tested the CPU so if none of these tests prove the fault then one can suspect the M/B but that would be last case.
Good luck.
