Why does my screen go black after a few minutes of use.

I’ve had the HP Victus 15 for quite a while now. During the first three to four months of using it, my experience was excellent. I was able to run some AAA games while still keeping up with my studies, which was everything I could have asked for. However, a problem eventually occur: the screen would randomly flicker and then go completely black. Even when this happens, the laptop would remain on, as I can still hear the audio from whatever video or game I was using.

At first, this issue happened about once a month, and I could use the laptop for several hours before the screen went black but over time, it has worsened to the point where the screen goes black after only a few minutes of use.

I have taken the laptop to multiple technicians in an attempt to fix the issue, but there has been no success. During the warranty period, I did not have the necessary funds to ship it back and request a replacement. So as of now I'm still searching for a technician or a solution to my problem.
