Black screen and GPU fan goes full speed

Hi! I have been using a Asus Strix Radeon Vega 64 card for the last one year. In the last couple of weeks, I have been facing this issue of when my PC randomly while playing a game (once even right after I just turned on my system and was still in login screen), the monitor goes black with no input and the GPU fans go to full speed. I can still hear the audio going on, but monitor remains blacked out without receiving any signal and its fan is going in full speed. Only way seems to be hardstop the PC and restart.

My rig also includes a i9-9900k CPU, Designare z390 motherboard, a Noctua D15 cooler and a Antec HG 1000W PSU. I checked a PSU calculator and it shows that my PSU is sufficient.

Also worth noting - I run a dual-boot hackintosh system (both OS are in different drives and its setup such a way that Windows is on the 1st PCI slot and never interferes with the MAC os or vice versa) and I have no issues running Mac OS Mojave and even during rendering/exporting 4k video, my system is very stable with no issues. This seems to happen only when I am using Windows 10.

I ran Unigine to test if my GPU is overheating but it doesn't really cross 75*C. I ran the test 4 times. The 1st & 4th time, at almost 70% through the test, the issue occurred again. The 2nd and 3rd time, it ran smoothly. During all 4times, my temperature didn't go beyond 75-76*C.

I did a complete clean install of windows again and installed the latest drivers [20.4.1].


Also worth noting, I am not a very technical person, so I've not fiddled with any of the settings in the AMD Radeon software (changing clock speed, voltage, power consumption etc.)

This issue is driving me nuts. Any help is really appreciated. Thank you in advance.
