580-137c Won't boot - Replacement MB?

[Rob1827]

The computer won't boot.  When turned on, the fans start at high speed and runs for 5 to 10 seconds then shuts down.  No beep codes or led codes (except as noted below).  The all fans except the video card were working.  Typically, it would try restarting by itself and go through the same sequence for several times or until unplugged. 

Here are some of the following troubleshooting I have done.

1. Plugged directly into the wall, Unplugged and held the power button down for 20 seconds.  Many times.

2. Used a new power supply, Corsair RM550.

3. Removed the Video card,

4. Unplugged Hard drive & Optical drive

5. Removed the DIMMs.  After removing the DIMMS it had a beep code!  2 long beeps.

6. Replaced the DIMMs with new DDR4 PC2400 memory.  No Beeps, No Power up.

7. Cleared CMOS - Ran longer and the fan speeds were normal.  However, on the next power on, it went back to the same symptom. Removing the DIMMS again (nothing else hooked up), had several different beep codes.

8, Replaced the MB battery (last resort). 

Any Ideas?  Seems to me it's either the Motherboard (possibly temp sensor?) or the processor.

A couple of questions:

1.  Is a replacement Basewood MB available?

2. If I use an aftermarket MB (300 or 400 series chipset), will Windows10 have an issue?

Any thoughts/comments/suggestions would be greatly appreciated.

I forgot to mention that there is no video display at all - no blue screen or bios menu.  The monitor does not see any kind of signal.
