My desktop suddenly is not going to sleep. Normally, it sleeps fine with the light blinking but now when I press sleep, it just goes out (no blinking light) and when I press back the power button, windows basically starts back over with an error. I don't remember the error now. It started this last week upon putting on FSX and my joystick. I do the Powercfg /requests command and it said there is no problem and nothing is blocking the PC from sleep. What could be wrong and should I try refreshing windows 8?
