Hi guys,

I am having a strange problem here. After some gameplay (and it only happens when playing games), i suddenly notice that the monitor shows the message that it`s not receiving any signal from the computer.
The strange is: I can still hear the sound of the game but only the song. If i try to shoot or do something else i can`t hear those things, only the song.
I tried turning off the monitor and turning it on again but nothing changed. I even had to format my computer and still nothing happened. After some minutes of gameplay (and it`s completely random), i lost the signal and have to restart the computer in order to use it again.
I had a R9 290X before and it never happened. Now i have a RX 470 and it`s happening, so i think it`s all about the graphics card. But what can i do? What can it be?
