Question PC Restarts randomly - Help!


Jan 21, 2013
Hello, everyone. My pc has been going strong for a couple years now, until the last week or 2 where it will randomly restart. I've made no alterations except replacing a nvidia 1060 3gb with an xfx rx 570. Even then, after replacing the card things were fine for a couple months.

Whether I'm playing a game and under heavy load, or just browsing the internet with chrome, the screen will go black. Then, the computer will restart most of the time. Sometimes rarely, it doesn't and the fans keep spinning (except the gpu). I took it to a repair man and he said it was a bad cpu so I replaced it with another one and it is doing the same thing. I updated all the drivers. I'm not sure what the issue is, but appreciate any insight!

My specs are:
amd fx-4300 Quad Core
16gb DDR3 Ram
gigabyte b450m ds3h
XFX RX 570
Corsair TX 750W
Seagate BarraCuda 2TB Internal hardrive HDD
