That appears to be an overheating issue.

Make sure the Fan is always ON and running.

Get Real Temp (Google), install it, run it and check CPU temperature while running. Look for high temperatures.

You may need to remove the CPU, clean it carefully and add a thin layer of new thermal compound.

In addition to John's comment: there are two leds, one - overheating of processor, second - of voltage regulator board:

Ok I removed the CPU and cleaned it and re applied Thermal paste but it still overheats. Fans are all working fine that I can see. could I be putting too much Thermal Paste?

Just a very thin layer so try that once more, otherwise the CPU itself could be faulty. Less likely, the power supply could be putting out incorrect voltages

I have already replaced the power supply too. I am at my wits end trying to figure out what is bad. I even replaced the graphics card but it did the same thing.. any other ideas. It is a new motherboard.

Have you confirmed it is the overtemp LED rather than the VR voltage LED?

check the temps in the bios, after the red light is on
that will show what is happening

Actually Customer decided not to proceed. but I am guessing at this point it was the CPU because i was using the old one and that was the only hardware that I did not replace.
