Question about Dell Dimension 4700 PC Desktop
After a while of use, my monitor just goes grey. Sometimes on start up it will be grey. We'll be using it and it will just go grey. We can hear the sound and still type. when i adjust the monitor, it shows the main menu for the monitor, so I'm not sure its just that. Can you help?
It sounds like you have a faulty plug. Here are some things to look for Look in the plug itself for bent or (this ones the biggie) Pins that have been pushed in to the plug, Make sure they all line up evenly. On some monitors there is a setting for "Degausing" try that one. If you are plugged into a External video card meaning one that is not attached directly to the motherboard, Open the computer and make sure the card is seated properly. If it is a plug that is directly on the motherboard check to see if there are dust bunnies or dirt around the socket. A lot of household lint and dirt have metallic salts and can cause problems. Clean it only with aerosal air and nothing with any liquid cleaner. Good luck... Be mucho blessed...Mark
