Ok so I have a sapphire nitro + rx 580 8gb and when i play certain games it crashes. I just built this pc btw and the only 2 games it runs fine are minecraft and league of legends, but when i run them both at the same time it crashes. The only other games ive tried are fortnite and csgo. Rn i have the latest drivers. I am running a corsair vs650 power supply, which is 650 watts. I also have done cpu benchmarks and furmark tests and everything went fine. I have tried a fresh reinstall of drivers I also tried not installing radeon settings. When it crashes the moniter goes black but my pc is still running. I then have to turn of my pc manually and turn it back on to get it to work. Any help would be appreciated.
