Display goes blank after a few hours.

[Guest]

My monitor display goes blank after a few hours or so despite the fact that
the computer is still in use. Along with that, the PC will not be able to
detect the keyboard as well. The cpu and fan is still running but i can't
seem put the display back up. The only solution was to manually restart the
computer. I have updated every driver and the BIOS but nothing seems to work.
I have reformatted my computer recently but the problem still stays. I'm
guessing it's a hardware problem. Is there a way out of this? Thanks.

In the control panel there is a power option that controls this. Have you
check that?

This happens to me as well. Before it would just put the pc into a low power
state if i left it on overnight. could this be a memory issue ?
