Screen keeps turning black when I play

Hello, I’ve recently had this problem with my laptop, every time I play or watch something it would suddenly turn off the display and like no sounds are coming out of it. I read a few reddit post and they say it likely causes of a black screen is GPU failure or PSU not supplying enough power. I think it might be the PSU fault because I checked my GPU’s health and updated the all the drivers and yet this problem still persist so I have to press the power button to turn off and turn it on again. I had this laptop for 2 to 4 years already and this problem just started a few months ago. If there is any fix to this please let me know because It is very annoying and irritating. Thank you!
