Do you remember making any changes to the computer recently?
This seems to be a connection problem or the cable is gone bad.
I would suggest that you connect the monitor to another CPU unit if you have this is to check if the monitor itself is gone bad. Also make sure that the connection to the monitor is correct. Also try connecting another monitor to the computer and check. This issue may also occur if the signal from the video adapter exceeds the scan range of the monitor. The video adapter setting for updating the screen (the refresh rate) is incompatible with the monitor.

This means that the computer is sending scan frequencies, horizontal and vertical, that the monitor can not process. Try using a lower resolution setting, ie 1024x768 or 800x600 and see if the problem goes away. Use your video card properties to change this setting.
It shows out of range because the PC is sending out the video signal that is higher than the monitor can display, you need to set the PC video resolution to the native resolution: 1024 x 768 @60Hz. You can reboot the PC into save mode (hitting F8 key while booting up) then set the resolution to 640 x 480 (try 1024 x 768 if it allows you to do so), reboot and reset the resoltion to 1024 x 768 @60Hz.
This issue may occur if the signal from the video adapter
exceeds the scan range of the monitor. The video adapter setting for updating
the screen (the refresh rate) is incompatible with the monitor. you should reinstall your video drivers in safe mode.
To restart in safe mode repeatedly press the F8 key during the computer startup. This will bring a menu where you'll be able to choose safe mode.
