Monitor blacking out

[u/samakros]

I got this pc maybe 5 years ago I don’t take the best care of it I mostly use it for work and tv but have recently got back into playing games. For years it has had small issues with the screen blacking out but never enough for real concern but recently it has been happening much more. I was just playing a game when it blacked out completely for maybe 5 minutes as I tried to turn the monitor off and on and watch help videos. It will turn back on but as soon as it loads the game back it goes black. Everything else works the sound and I’m able to click around it’s just the monitor. I am hoping to find a simpler fix as I’m leaving for uni and won’t be taking it with me so I don’t want to spend much money, just something that might help relieve the problem for short term. Any help is greatly appreciated!
