I've looked everywhere and can't seem to find what's wrong. My Pc will restart randomly playing games. I've checked the ram and i've tried to use WhoCrashed but no crashes will show up, ive ran stress tests on my gpu and cpu. When im playing a game it will go black and restart with no error message. Another example would be on fortnite if i play on low/medium setting it will last for a while but if i set it to high i'll crash almost instantly. https://www.bestbuy.com/site/cyberpowerpc-gamer-master-desktop-amd-ryzen-5-series-8gb-memory-amd-radeon-rx-580-xtr-1tb-hard-drive-black/6225214.p?skuId=6225214 (with rx 580) this is the pc i have and i dont have a warranty (yea i know i should of gotten one.)
