Screen flicker

So whenever I play offline or in a server (whether its hosted by me or by someone else) my screen sometimes turns black at random moments during gameplay for a few seconds before turning on again. Sometimes it does open at specific moments, such as when I open a map but again, it doesnt happen always. I never have this issue in other games. My friends do not suffer the same issue as me so I figure it has to do with my pc, but I don't know enough to fix it myself
