I have a fairly new pc which I build around ,2 years ago but recently I've been getting 'no signal' or 'entering power saving mode' on my pc everytime I try to play certain games for example : Euro truck simulator 2. Whenever I play ETS 2 it just seems to go into no signal in the first few minutes, my pc seems on, my keyboard and mouse stay on too, the same happened a few days ago when I tried to play sea of thieves, strangely, it went to no signal everytime I hit 'start game' but a few restarts later it fixed itself automatically.the temps seem normal going to 78 degrees max.
I've tried running various stress tests and even one for my psu because I thought that might be the issue but nope it didn't go into no signal once during the tests
My pc is way better than the recommended specs required to run ets 2 so I don't know what the problem seems to be
Pc specs
Amd ryzen 3 2200g
Amd rx 570 4gb
Corsair vengeance 8 gb ram ddr4
Corsair vs 450 psu
Any help would be extremely appreciated
Thank you
