Windows 10: mouse speed increases drastically on full screen applications

Hello,I would like to preface this by saying I have tried everything I could find: Disable Full Screen Optimization, Disable precision mouse thing, uninstalled and reinstalled the games, reinstalled my mouse software, swapped mouses, and am unable to find any resolution.Any time I open a full screen game, whether it has settings for mouse speed or not, I am getting the same issue. I even made a small youtube video showing the issue: https://youtu.be/nHnaMunrOMw - best I can describe it is my mouse speed damn near quintouples when I open a game. Its super annoying and is driving me crazy trying

Black Screen and drastic increase in fan speed randomly during game

Hi everyone, I recently have had issues with a consistent black screen during a gaming session that is always accompanied by a drastic increase in my fan speeds. My monitor will instantly say, "No Signal", and I can only turn off computer manually. I have the following specs:
Windows 10 20H2 (OS Build 19042.804)
CPU: Intel Core i7 9700k
GPU: NVIDEA GEFORCE GTX 1660
MBD: ASUS Z390-P
RAM: XGP DDR4 16GB Dual

I have had all the components since August 2019. I have also tried the following things to correct the issue:
- Properly confirmed Intel chipset drivers were up-to-date and not corrupted
- Performed a complete clean of my GPU drivers and installed latest drivers from NVIDEA using the Display Driver Uninstaller from Guru3D

The crash mainly occurs when I am in Overwatch, but it also has happened while sitting in the menu and in other games.

I am unsure how to properly address this issue outside of what I have already done. Has anyone had a similar issue or knows of further steps I can take to identify the issue or stop the crashing? Thanks in advance guys!
