The answer is actually, "both", and I'll get to that in a second. However, my main concern is that I reset the PC and can't seem to get to the initial BIOS status screen - that indicates more of a hardware issue, since I never get to the O/S. With regards to booting into Windows, I also randomly see something odd: The screen will get stuck on the "Starting Windows" screen (before the glowing Windows logo starts to zoom into the screen. Once the logo appears, everything runs great (usually).
One thing that I have noticed though for both "stuckiness" issues: If I wait a minute or two, the PC usually eventually gets unstuck and boots normally after that. And, by "a minute or two", I mean exactly that. Sometimes, it has taken slightly over 2 minutes before the initial BIOS Status screen shows up, after which the PC will boot up OK. I have also seen the PC get stuck at the "Starting Windows" screen for a little over 90 seconds before the Windows logo appears and the PC boots OK after that.
Did my answers clear anything up? I'm really at a loss. It sure would make things a lot easier if something actually failed during stress testing. I've run OCCT LinPack 90% memory for an hour, and no failures have ever shown up. The CPU temp gets up to about 60 DegC, but everything runs fine. Also, I haven't seen any sort of "stuckiness" once I have fully booted into Windows (Thank goodness! But, I'm keeping my fingers crossed!)
If the CPU light is still coming on, then I can't help but think it's the CPU or PSU. If you have run memtest86+ on each stick individually or tried just putting in 1 stick alone and still get RED CPU lights, then there has to be something wrong on that end. You've already gotten a new board.
I'm somewhat ignoring the issues with Windows. I know you don't want to because you need to run your business, but if you can't get stable with simply posting the machine, then you aren't going to be stable in Windows either...
At this point, I would try another power supply as Kizwan mentions below or another processor. I would strip the machine down to bare bones. CPU, 1 stick of ram, power supply, keyboard, dvd drive, and mouse. No video card, no extras plugged in. Reset everything to defaults and configure ram stick to appropriate settings. From there, see what happens with the Red light. If it comes on again start replacing components.
Perhaps Dubbed or Kizwan have some more ideas, but I'm basically out of ideas. Again, if you are getting post issues, those take priority over Windows issues.

EDIT: Cooler Master Silent Pro Gold 800W has 4+4 pin EATX12V connector. So, I understand now when you said "other 4-pin" in your previous post. However, I still think you should try another PSU.
I agree with this. This couldn't hurt.

Dubbed didn't you use AI Suite to flash your bios instead of using a flash drive instead?
