Problem with the GPU (i think)

[xxxdenisxxx7]

Whenever i leave my PC on and go away, the screen is workign but shows nothing, like it gets no signal from my pc, this might happen after 20 mins or a few hours, If i reboot my pc the problem stays the same which forces me to turn off and on the power supplier (dont know how its called lol)
ive got a gtx670, latest drivers.

Open control panel, go to the power settings. Check the times for the computer to go into Sleep/Standby/Hybernation - then turn it off.
