I've built my own PC about 3 weeks ago and yesterday i was playing Warzone and the whole PC shut down. When i tried powering it up it powered up normally but the GPU didn't. I checked the cables and everything. Then i used an old GPU i had laying around and it turned on just fine. I don't know if i messed up the components maybe they're not all compatible but it worked fine till now.
the components:
CPU: Ryzen 7 5800x
CPU Cooler: Cooler Master MasterLiquid ML360R RGB
Motherboard: Gigabyte Aorus B550 Elite V2 ATX AM4
RAM: Crucial Ballistix 32gb 3600mhz
