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!

Your graphics card is crashing. It might be caused by heat during gaming. Do you overclock your graphics card? See if you can increase your fan speeds on the card during gaming.
