Problem with PC when using demanding games

[plasma]

Hello good day, I've been having a problem with my pc, I'll tell you about it below. I have an Rx 570 and my problem here is that under stress (and by stress I mean putting a bit more demanding games) the monitor stopped giving video and I could only turn it back on by restarting the pc from the front panel, so I cleaned the graphics card because I thought it was because of the temperature but it still happens only that now it's for seconds and it gives video again without needing to restart it, the temperatures they are at are 50 degrees, someone could tell me if they have any idea why this happens and if it has happened to them?

50ºC for a graphic is nothing.

If you want to improve the cooling in order to do some tests to confirm if it can be another component, put a large fan blowing towards it and leave the tower open.

Salu2!
