So I have a new pc ( win 7 ) with r9 200 series and sometimes when i leave the pc on for a long time the screen shuts down and becomes black.. pc is not in sleep since i can hear everything is working. even the sleep mode is off. mouse and keyboard are working. but not screen. and nothing like pressing a key or moving the mouse can wake it up. even pressing the power button doesn't do anything, nor pressing the reset button will bring it back. I have to turn it completely off by press and hold the power button and turn it on so i can get the screen working again.
Motherboard: MSI 970 Gaming.
CPU: AMD Fx 6300 6 core 3.5 ghz
Power supply: nex 750 w corsair gold.
Please Help..Thank you
As a temporary workaround, please try disabling Monitor sleep via the Windows Control Panel > Power options.
