I've had experience of several bad CPU. Having said that, and in view
of the tests that the OP has done, BIOS settings are the first place to
check. The other is the CPU psu itself. I've seen bad capacitors
cause the psu to shut down on heavy load but supply power just fine to
a lighter load, ie a CPU that draws less power.
The other suggestion I would make is to check the BIOS beep codes to see
what the beep code means.
