When i use my PC after a random amount of time the monitor turns off and says "no signal". When i restart the pc it works again.

I tried both hdmi and displayport same results so probably not a damaged cable or port, and i think its not a graphics card issue because i had that same issue with a different card as well.

What exact model PSU do you have and how old is it?

What exactly do you mean by:

You mean you turn it on and then it sits idle for a while and you go to it to use it this happens or you mean when it's off for a few hours/days for example and you turn it on to use?

Have you checked Event Viewer to see if there are any erros or waring of things that happen when the screen goes off?

Well that PSU is not a very good quality one I think. Is this your PSU here?
It doesn't have OCP (Over Current Protection) and OTP (Over Temperature Protection) and has passive PFC (Power Factor Correction) so it's not very efficient either.

Since you mentioned that it happens after a while (after gaming and such) it might be due to PSU getting warm and starting to go out of whack.

On the same note, have you moitored your temperatures, CPU and GPU? At idle and while under load, such as gaming? You can do that with HWiNFO from here. The portable version doesn't need installation.

That is because the system is not properly shut down and loses power. That happens if you force shutdown or reboot the system when it's on and in Windows.

I forgot to mention that the pc sometimes only runs for a couple minutes and black screens.
And i dont think its overheating.
