To troubleshoot, I've examined the CPU thoroughly to find no bent pins, replaced the thermal compound and set it back in. I've also ran intel diagnostics on my CPU and it passed (not sure how that works though). 

So having done all of this, leads me to two things. Memory and my Motherboard. Please, if anyone can help me try and figure this out, I'd be really grateful. Here's what's going on.

Suddenly, my pc locked up while playing Ark Survival on the Xbox hub "Play anywhere." I had no choice but to force a pc reset, because it was completely frozen. While booting, it would go straight to this blue screen giving me a 0x0000255 error. I tried everything, finally ended up reinstalling Windows 10 (for the first time). Pretty much I've done this now around 8-10 times on various SSD's trying to figure this out after replacing so many parts, I'm damn near broke and hopeless at this point. My pc is up and running currently, but I can tell when I load any game that something is very wrong. I get jittering pauses throughout the time I play so I just exit the game and don't bother playing. 

Any and all help would be great if anyone else is having this issue or if support could possibly lead me in the right direction with testing my RAM or even how the sequence goes to make sure I have it correct.

In the mean time, try a full CMOS clear:

While you have the battery out make sure you reseat your RAM and GPU, check the slots for dust and debris that my have gotten worked in there. Basically, think about all your PC has been through since you built it and check for things that could cause problems. How dusty was the inside of your PC? Do you smoke? If you do then tar builds up inside the PC in a thin layer, this can block contact on things like memory and your GPU. Take a clean rag and some isopropyl alcohol and clean the contacts of both your RAM and GPU before reinserting them. 

Let us know how it goes.

I've literally tried everything. Followed the 16 steps on Toms Hardware to a T, purchased a new PSU for nothing and several other components.. for nothing. I'm getting a normal startup beep, as though it's running fine,  then begins to load windows but freezes at the black screen, just before it loads. 

Yes, as I stated previously, which I quoted above again, I'm very careful not to push too much air where it shouldn't be pushed. I hold the nozzle 2-3 feet away just to get the dust out. I don't use it as an air cleaner or sand blasting technique. lol

Ok, tried the fan on the i/o panel, no changes. 

As for the response to what specific PSU I'm running currently. I purchased a Corsair HX1000i about 2 weeks ago. Turns up I didn't need it, but that's what I'm currently using, it seems to be a great PSU for my system. 

Even if the RAM is good, there is a chance the IMC (integrated memory controller) on the CPU has conked out. If memory serves, we saw a fair number of instances of X99 CPUs needing to be RMAed with this issue when the platform was new. 

This is certainly a tricky one.....
