PC stuttering when opening programs

Alright, so this has been happening on and off for a few months, but I can't take it anymore. I first noticed this playing League of Legends. When I would leave the client and load into the game, my computer would start lagging horribly and it would stop after the game finally loaded in. The only game I can for sure recreate the issue is Ori and the Blind Forest. As you can see from booting the game my discord voice goes all robotic and my mouse is extremely delayed. In the video I'm doing little circular and side to side motions and it's not fluid like it should be.

What I've tried:
Cleaned inside pc checked cables (nothing looked out of the ordinary)
Used DDU to wipe drivers and reinstall (didn't help)
Ran Memtest86+ (no errors)
Wiped all drives then reinstalled windows (done this 3 times before but did another yesterday)

I have no idea what's causing the problem but I'm assuming it's a hardware problem. I think I've narrowed it to either the CPU, PSU, or Motherboard. Below I'll post my specs to allow more insight for you guys. Any help at all would be appreciated. Thank You

CPU: Intel Core i7-5820K
Cooling: Corsair H100i
Motherboard: ASRock X99 Extreme4
RAM: Crucial Ballistix Sport 16GB (2x 8GB)
SSD: Samsung 850 EVO-Series 250GB
HDD: Seagate Barracuda 2TB 3.5" 7200RPM
GPU: 2 Gigabyte GeForce GTX 970's
Case: Rosewill THOR V2
PSU: EVGA 850W 80+ Gold
OS: Windows 10 Pro

Is this game installed to the SSD or to a HDD? Is the storage device nearly full (capacity-wise)?

I installed it on both and the problem persisted on both as well. I switched from DisplayPort to Dual Link DVI and the problem is still there but not as dramatic. I'm thinking it's a hardware problem but can't find anything out of the ordinary.

I tried resetting the pc and wiping drives but it got stuck at 10% and screwed me over, had to format the drives and reinstall windows. I know more than an average pc user but not enough to handle this. Also there is quite a bit of people with this problem but nobody has a solution.

If you remove one GTX 970, how does the system perform?

What, if anything, are you overclocking (CPU, GPU, memory)?

What are your CPU and GPU(s) operating temperatures at idle and under load?

Are you using the most current BIOS version for your motherboard?

Did you install the chipset drivers from Intel or the ones installed by Windows?

1. I have never tried to overclock anything
2. they seem normal at idle, should i use a stressor to check under load?
3. No I will update that
4. I have no clue i just used intel driver update utility and everything is up to date

I'm also going to try and reinstall windows 10 from a USB drive. The disc I used might have been an update disc i thought was a fresh install.
