I cleared the CMOS. Here's the thing fellas, with the CPU removed the machine stays on, no shutting off and restarting. With the CPU installed it shuts down and restarts ad nauseum. I tested the power supply and all give proper voltage.
My video card was keeping my PC from booting POST. Try that. I replaced the PSU and motherboard instead of checking the components; cleared the CMOS, even changed the battery. NowI have an extra PSU, MB and a battery!
