Hello, i recently finished building my PC (first build ever!
) and was experiencing some problems while playing certain games. It happens while playing and the monitor just seems to lose signal. I try doing all command prompts while this has happened and i get nothing. The only solution is to restart the computer which upon reboot seems to find the signal just fine. I really don't know what is going on and need help
