Hi, I have an Acer Aspire desktop x3900, it came with an Acer monitor x223HQ. All has been well since i bought them a year ago. I have the monitor set to turn off after 20 mins and the desktop to go into stand by after 1 hour.Only recently, i find sometimes the monitor will not wake up when i move the mouse. The pc is active, its blue neon light is flickering ( when its in standby it flashes on and off )
The only way I can get the monitor to respond is to power the p-c off, using the power button. Ithen get the message that windows shut down incorrectly etc
I am thinking of setting the monitor and pc never to sleep/standby. Can anyone offer any advice. Many thanks
The pc is windows 7 home premium, 64 bit

When the computer was sleeping did you try anything else? Such as pressing keys on the keyboard, clicking the mouse (instead of just moving), or turning the monitor off and back on? Here is an excerpt from Microsoft regarding power states in Windows 7, and the link provides instructions for changing your power settings as well.

On most computers, you can resume working by pressing your computer's power button. However, not all computers are the same. You might be able to wake your computer by pressing any key on the keyboard, clicking a mouse button, or opening the lid on a laptop. Check the documentation that came with your computer or go to the manufacturer's website.

I figured you had covered that already, but just wanted to be sure, I've had a few systems that only responded to a mouse click or keyboard press rather than just moving the mouse. Did you end up changing the settings so that it no longer goes to sleep/standby? Are you connected via VGA, DVI, or HDMI? Have you tried removing the cable and re-seating it when the computer is running again?
