So one night I was getting off of call of duty and my pc randomly got a gray screen and then the monitor would go to rest mode and the fans go to 100. I’ve tried a new power supply incase it wasn’t getting enough power but that didn’t work.I tried reinstalling windows on a new hard drive as well. I reseated everything and made sure everything was plugged in properly and there’s been no fix.
And I can’t access my desktop anymore after this happened the first time I only get the loading screen before loading into the desktop and then I get a black screen and then the pc fans go to 100 and the monitor enters rest mode.
pc specs:
Graphics card:1660 super
Cpu:i9 9900k
Power supply:850w
Ram:32 gb

Check the temperature may be cpu cooler not seated properly or gpu temp.
dont overclock cpu or ram anything run on stock.
try one stick of ram only.
clear cmos remove cmos battery and install it again and load default settings in bios.

I did everything you said and it still didn’t work. So I took a older graphics card and put it into the computer and it boots up just fine I can access windows finally. But do you know what could be causing my graphics card to do this? I also usually run a double monitor setup as well.
