Question Display turns off and fan goes full

[Simonwski]

Hello there. Recently when I turn on my pc it goes normal, but when I start playing, after like 5 minutes in game, my monitor turns off and my fan goes 100% without reason. After that I tried to restart my pc and most of the times I can't even see the windows welcome screen because I have to wait 1 hour straight before my pc "goes normal" again.

I tried to update my bios, videocard driver, cleaning the fan just to see if it was just dust but nothing changed at all.
It's not overheating because my GPU temp was 50°C


My PC specs:
Motherboard: MSI MPG X570 GAMING PLUS
CPU: Ryzen 5 3600
GPU: MSI RTX 3060 Ti
SSD: Samsung 970 EVO SSD 500 GB
RAM: Crucial Ballistix 3200MHz 16GB (2x8)

I've only seen that type of behavior when it's a power delivery issue. Unfortunately this isn't necessarily limited to just the PSU as the card itself can have been damaged or failed. I would suggest installing 3dmark and run it while having GPU-Z opened to the sensors tab and look at what the temps and power usage looks like. Just watch that with a looping run of 3dmark to see if anything happens before the crash occurs.

If you have another card you could test in your machine you could at least likely rule out PCIe slot power delivery/motherboard. You could also test your card in another machine if that's a possibility. Since you've tried a different power supply I'm inclined to believe it's likely the video card itself, but cannot say with certainty.

I tried to put my gpu inside another machine (without downloading drivers) and it worked as it should. I played games and watched some YouTube videos to "stress" it and nothing bad happened. I'll try to reinstall windows and drivers to see if it fixes my problem

I reinstalled windows and drivers and I thought it worked but after 2-3 hours it happened again
