A new system I am building and having problems with gives NO P.O.S.T. beeps at startup even if there is no RAM on the board, how do I ascertain if it is the processor or the Motherboard that is the problem?

My thinking is that the system "should" provide P.O.S.T. beeps regardless of the processor working or not working as it is controlled by the MoBo and not the processor.

PSU has been tested as good and the MoBo IS getting power

Your thoughts on this please?!
Make sure mb isn't shorting. Try to power it up on a workbench outside of the case. I had this happen once and it was because I had shorted the mb.
Stripped the system entirely, placed the MoBo on a Phone book, installed processor and processor fan ONLY with NO RAM, no cards, no drives.

Plugged in the main power connector to the board and the 2x2 connector for the processor and then shorted across the power pins and SAME result, powers up but NO POST beeps or anything else!!!


Known good name-brand power supply of sufficient wattage? If not you
know what to do.
Yep tried, NO JOY! Looking at a faulty MoBo right?
