After an extended period of time usually 12+ hours my monitor will automatically go blank and the green light signaling the monitor is on switches to orange which signals it's turned off. The computer itself remains on though. To resolve this problem I turn off the computer and I switch the power supply on the back of the computer to off and then back on and restart the computer then everything works fine. However, the problem reoccurs again after another ~12+ hours and I have to keep resetting it. Thanks if you have any idea why this might happen.
