Hello. Firstly, I am sorry if I posted this in the wrong section.

For some reason, for 1 week, whenever I've been playing games my screen starts to go black/lose signal/ or something similar, making it be impossible for me to use the pc. A few days after this started to happen, my screen went black even when I've been watching youtube videos. Then this happened even when I simply opened my internet browser. I tried changing all monitor cables, the monitor with another one and even re-installed windows(and the latest drivers) and yet this problem still occurred.

The PC still has warranty, so I took it from where I've bought it to get it fixed. They told me that it worked just perfect, there were no black screens and that they "stress tested" the pc and it worked just fine. So I took the pc back home. For one full day I noticed that there were no black screens . After that the black screens have returned, but only once every hour or so which was bearable.

Now, for some reason the screen goes black every few seconds while gaming again. Here is a YouTube video of my problem https://youtu.be/arxj1C_N5Uo?t=15s . As you can see, the monitor power button still remains on, and even if the screen is black the pc still keeps on working just perfect.

Does anyone know what am I supposed to do? And what might be the cause?
Thank you very much in advance!!

Edit1: The GPU temp when this first happened was 85 degrees celsius. I've managed to lower the temp to 60-65 by maxing out the fan speed and lowering the game resolution. (Settings are on low)
