I have found that this specific motherboard has a consistent issue across multiple forums.

My friend sold me his dead PC that contained:

MSI 970A-G43 motherboard
NVIDIA GeForce GTX 670 card
2x 8GB sticks of Corsair Vengeance 240 pin DDR3 1600mhz RAM
AMD Phenom II Black Edition
and some shitty PSU branded by Rocketfish?

He always mentioned the PC randomly shutting off after some time of gameplay, he assumed it was just collected dust and/or faulty PSU.

I bought his PC off of him for a measly $100 and went straight for a new PSU (EVGA 80 PLUS 600W, I've used this specific PSU myself in the past.)

I gutted the PC, dusted and cleaned every inch, removed all parts excepted the motherboard and CPU, removed the heatsink and cleaned off the old thermal paste on the CPU and heatsink with a very delicate cloth, reapplied new thermal paste, remounted the heatsink, added new PSU, firmly checked all connectivity, and went for the boot.

I first had an issue where it attempted to boot every second in a repeated loop, I think a cable was loose after I checked a second time and it managed to start up, fans all spinning, blue LED on motherboard, and 0 issues from the looks of it.

I hooked up my keyboard/mouse via USB and an HDMI from my monitor (also tried DVI), and no lights / video signal to either of them.

I have removed RAM, used only 1 of both sticks in all 4 separate slots to no avail, cleared CMOS via the battery, triple checked all connections, etc.

The only thing I have not done is moved the GPU to the 2nd PCI slot, but I don't think this would correlate with the USB drivers not being picked up...

I'm assuming the board is toast considering all of the other threads regarding this specific motherboard.

Shoot me some new options if you have any, Thanks!

Some people just don't have an expendable amount of hardware when trying to work on a budgeted build.

My main build is an Intel CPU, so that defeats the purpose of testing the CPU/Mobo

The GPU wouldn't cause the USB functionality issue.

And my PSU starting the PC and spinning the fans explains how the PSU isn't the issue.
 
I purchased a Gigabyte 78LMT-USB3 AM3 motherboard and I've gutted the case, put everything in, replaced the old MSI board with the new Gigabyte board and still the same issue...

The Gigabyte board has onboard graphics so I've removed the card and also removed RAM and still the same issue.

So, I'm assuming the AMD Phenom ii is just fried?

Let me know what you guys think, I'd appreciate the help.
