High End Computer Stuttering in Games and low FPS

Heya guys,

My computer has been lagging essentially since I made it around a year or two ago. It seems to be getting worse and I've done so many tests now and just cannot find out what it is.

OS: Windows 10 Pro 64-bit - Reinstalled 10000 times on both HDD and SSD
CPU: Intel Core i7 5820K @ 3.30GHz - Haswell-E/EP 22nm Technology - This was bought as an OEM product.

RAM: 16.0GB Vengeance 3000mhz - overclocked to 3200 bc XMP crashes PC - (16-19-19-38)

Motherboard: MSI X99A SLI PLUS(MS-7885)

Monitors: Main - Acer XB240H (1920x1080@144Hz)
Second- HP 2311x (1920x1080@60Hz)

GPU: 8GB NVIDIA GeForce GTX 1070 - Palit

PSU: 750W Corsair CX750 80+

Storage
1863GB Western Digital WDC WD2003FZEX-00Z4SA0 (SATA)
931GB Seagate ST1000DM003-9YN162 (SATA)
238GB SAMSUNG MZVPW256HEGL-00000 (M.2) - OS on this


The SSD is brand new and the stuttering persisted before this, same with HDD. Also I play some games on the SSD and some on the HDD and it has the exact same problem so I'm 99% sure that these aren't the problem.

I've bench marked the GPU and stress tested it. The GPU came out with a high score and the stability was 98.6% stable.

The RAM I've tested using memtest for 12 hours. It passed 3 times and got halfway through another before I stopped it. I also tested everything with AIDA 64 and nothing showed up weird. I watch graphs, temps etc while playing games and there are no weird spikes or drops when this lag happens.

Nothing else is overclocked except the memory by 200mhz.

This stuttering happens in most games as well as it not running at what it should. For example, even minecraft runs at 80fps and when I destroy a block it makes the frame rate drop. I mean minecraft... Other games like overwatch run at around 60-80 when it used to run higher and tarkov runs at 40 FPS but that's not really saying much.

There was a time my PSU did blow, sent it back and got a new one which worked fine. It was caused by a short circuit due to a fan being plugged in at both ends and I didn't notice.

I did stress test my CPU which didn't cause the same effect in games but it did recreate the same effect it has when opening some games which is everything lagging out including the audio and making everyone/everything sound like robots.

There's probably other tests I've done that I've forgot to mention but that's it really on top of the temperatures all being very acceptable.

 
Solution
I had issues of this sort when started overclocking AMD FX VIshera 8350 back in the days (I don't overclock anymore) when gaming stuttering happens with some overclocks that seem to be stable but I think CPU voltage was not appropriate, it's like borderline tolerable overclock system does not crash but performs strangely.
I would run system on stock clocks everything, disabling all power saving feature in bios and having it run on high performance power scheme in windows, and disabling automatic CPU overclock in bios if applicable and make sure memory and CPU voltages are at their default values.
Monitor temps and voltages (delivered to CPU) closely
Run video card at stock speed

Reseating CPU and checking it's pins, reseating video...

In NVIDIA control panel it doesn't have the option to turn it on an off so I can't say but in 3D settings it is VSync is set to off. The problem persisted before I got this monitor and I always play with V-Sync off. There is no reason I should turn down my refresh rate and anyways, my second monitor is 60hz and it does it on that too.

Reseating CPU and checking it's pins, reseating video and ram, checking cables and connectors, testing with bare minimum hardware connected to mobo +++, or even better with the mobo flat outside the case. Sometimes a hardware part swap gives much faster diagnosis than 100s of tests, if you have extra hardware laying around consider swapping RAM at least or PSU.
Also worth the try with windows 7 64

It could be just some hardware incompatibility or a defective circuitry in mobo or CPU too.
Good luck.
