Intel S2600CP Motherboard 1-5-4-2 then 1-5-4-4

Hello Members,

I have a motherboard Intel S2600CP running inside a Coller Master Chasis for 2.5 years and it was replaced. Now I have a new replacement board, 1 Xeon CPU and 32 Gigs of Ram. The PSU has been Changed to Antec HCG-850W.

Here is the problem;

1. I installed Windows 10 on this and it worked fine for 2 days; After a sudden power cycle; it will boot up and then reboot automatically couple of times and then the beeps would be 1-5-4-2.

2. This continued couple of times. Clearing the CMOS and waiting for the 2 green light to glow; did the trick I was able to boot up; I read that from a thread linked below.

3. I updated BIOS to S2600CP_EFI_BIOS02060006_ME020107328_BMC0128r10603_FRUSDR111 and there was one successful boot to OS after this

4. There was a software BSOD after this; and now it does not POST even after clearing the CMOS. The error code now is 1-5-4-4 and the light stays at amber

Any suggestion where the issue lies?
