Green screen after gaming

[sebastijan.spoljaric]

So I recently bought a new gpu -RX 580 8gb and since then after playing games for a while a green screen or evrn brown/grey screen appear and I cant do nothing but restart my pc.I installed latest drivers for gpu.Gpu temps are normal but my cpu goes over 90 degrees.It went the same with old gpu but never crashef like that.What coule be a problem.It ussualy happens after some time and not in all games.Forza hor 4 works fine but rocket league and league of legends seem to crash ,i even underclocked my gpu but that didnt work too.

Your cpu should not be going over 80 degrees Celsius . You need to A. set cooling fan to higher setting, B. get a better cooling set up.

But why does my pc crash on some games and some not?
