Question Fps drops, robotic sound

[feste2222]

Hey, could someone one help me with screen freezing (fps drops) and robotic sound? I have been using my dads pc when he isnt on it bcs my motherboard is broke and I have sent it for repair. It happens when I am playing games rn (GTA V, WoW), sometimes I can hear robotic voices of friends on discord even when I am on desktop or just browser. I thought it was cause of high usage of ram or cpu but both where fine when I checked it through amd overlay while playing.

It happens sometimes when I'm playing league of legends or CS GO (mostly cs go). Firstly, an overheating pc or laptop is going to cause your fps to drop and the processes to freeze, considering you have the specs to support the games, as do i.
My instant fix is not running ANYTHING in the background. Not chrome, steam chat, any app that is not the game. Works for me :/
