All PC Games randomly crashing on new build.

[Colexinan]

I built the PC around Christmas, and so far every single game I've played(~15 different titles) are randomly crashing, except for league of legends.

Specifications are:
CPU: AMD Ryzen Threadripper 2950x
GPU: MSI NVIDIA RTX 2080 8gb
RAM: G.Skill DDR4 Flare-X 4x8GB 3200MHz
Mobo: ASRock X399 Taichi
144hz Monitor

The PC is mainly used as a workstation, but on the off-time I'm playing games. All of the games just randomly close after 1-4h or minutes. The most common error that I get 99% of the times is "0xc0000005" from the event-viewer, which doesn't really help.

What I've tried so far:
Reinstalling/Repairing - Visual C++ Redistribute
Repairing/checking windows for corrupted files
GPU Drivers updating and downgrading.
I've checked temps during gameplay as well and they're fine(GPU avrg 62c, max ~71c, idle 29c),(CPU avrg. 50c, max 62c, idle 32c)
BIOS is on the latest version.
Different DP and HDMI Cables.
I've ran memtest86 for ~30 hours and there were no errors.
Also ran Furmark for 2 hours without any problems.

I'm out of ideas, so any suggestions are appreciated.

How you tried a intensive hard drive test?

How you tried a intensive hard drive test?

I did all HD Tune tests on both SSD and HDD, without any errors. Also I've been running multiple benchmarks to try and stress the gpu as much as possible, and I haven't had any problems. This issue occurs only with games.

Hi

With what you have done and if you are sure the bios is the correct one for your board and completely up to date. Leaves the power supply not up to the task. I would think you would need a good quality power supply at 700 watts +. And you are running windows 10 64bit ?

My PSU is 1000W, and the windows is 64bit as well.

Hi

What 1000 watt power supply do you have and what sockets are you using for the memory modules.

Hi

What 1000 watt power supply do you have and what sockets are you using for the memory modules.

PSU is  EVGA SuperNOVA 1000 G3 1000W.

Memory is slotted in DDR4_D2, DDR4_C2, DDR4_A2, DDR4_B2 - as instructed from the mobo's manual.

Memtest86 should be run on this to rule out a memory module as the cause. Run it through 3 full tests minimum.

Additionally if you have any overclocking going on, shut off the overclocking and run everything normal clock and see if it then behaves. I have seen overclocked systems look fine and then crash on games that push the overclock and they point out stability issues with over driving the CPU or GPU or both.

I already mention in the main post, that I've ran memtest for over 30 hours without any issues found. I haven't done any overclocking as well, and I just reinstalled Windows. I'll try swapping the GPU for a friend's 1080 in the coming weeks and see if issue persist or he starts to experience errors on his PC. Meanwhile I'm still open to suggestions.

use the gpu-z rendering and test gpu also what temp you have on system parts any overclock on it

XMP enabled? Disable it. Use default timings too.

Check DRAM voltage is at manufacturer's recommended voltage.

Maybe try an underclock to 2133MHz just to see?
