PC freezing and bluescreen problems

[sellXD]

Hi.
I extra signed up here because i'm getting hopeless on trying to figure it out myself and idk if this is the right hub for that so srry <.<
so anyways my problem is when i play League of Legends my PC randomly freezes for 2-4 seconds
that only occures when i got a youtube video or wallpaper engine running on my second monitor
when the freeze happens the youtube video on my second screen gets stuck with either a black screen or premanetly repeating the same 3 frames while the sound continues normally and the only way to recover the video is to skip to a diffrent point in the video.
on wallpaper engine the BG just dissapears and reloads in.
when that said freeze happens every time i want to shut down my PC i get a bluescreen of death with the error message kernel_security_check_failure.

 

This problem only happens when i play League, it never happened in any other application or game yet
i already tired updating every single driver i could and nothing has worked so far
if i can't get a fix for this problem i'll probably try to reinstall windows once again -.-

 

hope anyone can help me and have a nice day

 

my specs would be:
MB: Asus STRIX Z390-E Gaming
GPU: 2x ROG STRIX RTX 2080 OC with NVlink (also from ROG)
CPU: Intel i9 9900K overclocked to 5GHz
RAM: 4x8GB Corsair Vengance 3000MHz
OS: Windows 10, version 1903

Based on the description provided, looks to be an issue with the video driver causing the crashes and the odd behaviour on your second monitor. Likely due to corruption of one of the driver files or a critical windows system file. I would test to see if you get the odd behaviour outside of windows in a linux live environment. If everything is good there, reinstalling Windows would be your next step.
