I have a Desktop PC running Windows 7 (64 bit)
Recently when I leave the computer on for a long time (unattended) the monitors only go to sleep mode ( maybe the GPU???) and not the computer itself: And the monitors do not wake up from sleep mode!!
The computer is constantly on, I can see the lights on and the fans humming, computer is running, but the monitors ( I have dual) stay sleep, in standby mode, no matter how many times I hit the keys on the keyboard and wiggle the mouse etc. the monitors don't turn on,
But I can tell the computer is wide awake: I have the Power Options on "Balanced" with
"Turn off display" on 10 minutes and "Put computer to Sleep" on 30 minutes, these used to work just fine, a simple tap of the spacebar woke up the monitors and the computer.
It's worth to note that recently I installed an HP mini media keyboard and a mini mouse as a secondary mouse and keyboard for the coffee table, and they both run on a micro USB 2.4Ghz receiver, I have a feeling These may be interfering with the PC's Sleep options? My main Keyboard/Mouse are an old USB wireless Logitech Kb, and an old Logitech wired mouse. Please help!
