Hello, Ever since i built my new PC over a year ago I've been getting BSODs and freezes.

Got the I7 7820x CPU, which i had so many problems with, "WHEA uncorrecable error".
Sort of got passed that by increasing the VCore.

Anyway my PC is still freezing very predictably when running certain games or software after X amount of time.
But only when i use my main monitor 3440x1440 21:9 resolution connected through DisplayPort.
I should add it is a dual monitor setup.
My GPU is 1080 ti.
I've been monitoring the temperature of both CPU and GPU at the time of crash and they are both what i would call normal at around 70-80C for the GPU and 40-50C for the CPU.

I've tested a game i know freezes my PC on my main monitor after about 30 minutes on my TV(1920x1080) and it doesn't freeze on the TV.
Some software i've managed to increase the stability and FPS by tweaking the NVIDIA control panel settings for that specific software but it doesn't always work.

So im not really sure where to look from here and i would appreciate some help.

Its usually a hardware error. Try the following fixes and let me know if the problem persists

1) Disable overclocking and reset bios
2) Check Hard drive for errors using the windows tool.
3) Reinstall and update all your drivers. And update windows too.

Well, I updated my BIOS yesterday. An update that is supposed to increase CPU stability. I reset it then and had the same issues without any overclocking.
The disk is a relatively new M.2 NVMe 960 evo so i wouldn't expect there to be any problems with it.
Also the problem has persisted through several clean windows installations and i'm always keeping up to date.
