Black screen after few mins of playing any game

[Mazen Adel]

lately I have been getting this problem where after 5-10 mins of playing any game the computer screen would go black, the PC itself stays on tho, fans keep spinning and also interestingly I can sometimes hear the background music of the game (note that I should be hearing more then just that usually) this problem also came suddenly I used to be able to run most of these games perfectly normal, at first I thought that it might be a power supply problem so I bought a new Corsair CX650M PSU but the problem continued which lead me to believe it might be from the GPU, I tried reinstalling the graphics drivers and removing the GPU and cleaning it but no luck. any help?

here's the specs they are pretty low end tho:
GTX 750Ti Zotac
I3-9100F
h310m gigabyte S2h
8gb rams
Corsair CX650M



Thanks, in advance and sorry if my grammar isn't that good, English isn't my native language.

If you can try getting your hands on any other graphics card to test in the system to see if the problem persists. One simple thing to try is switching display outputs so if your card has other ports try them as its worth a try.
