Question While playing a game and having 2 monitors my monitors turn off (no signal)

[ttopaz]

When playing a game (Fortnite, CS: GO etc...) and I have both monitors connected to my GPU it randomly crashes after a while I have an RX 580 Nitro from Sapphire and an AMD FX-8350 on a Gigabyte motherboard. I'm not sure what to do to fix it because it's not my pc I have 14gb ram and a 650w PSU and I can run both CS: GO and Fortnite at once when using only one monitor. It doesn't crash when I have both monitors on and I'm only on google chrome or word and I would really like to be able to play a game and have a second monitor on as well. Any help would be highly appreciated. Thank You.
