    Okay, so my problem is that my screen flickers everytime i type ANY charactor, have ANY mouse movement, or ANYTHING is being loaded. I have already reloaded my video card drivers and that did not help. I see horizontal lines every time i type, then sometimes the whole screen goes black untill i stop typing for a few seconds. I assume this has something to do with refresh rate because i only have a problem when something moves or new is added like a new letter to this paragraph. I would also like to mention that some letters seem to be jumbled for a moment, then when i type again they are fixed. I am not editing my thread because when i submitted this i was givin a message on a black screen that said "2 Digital input cannot display this video mode."

    Thanks for your time, and hopefully someone can help!

    FYI it is a Dell LCD monitor of 17", approximately 4 to 5 years old.

    Sounds like the backlight is about to go out. There is a fluorescent tube inside the monitor that has only so many thousands of hours of life,like fluorescent lights at the office. My friend used to repair LCD monitors. When you buy refurbished LCD monitors,they are used monitors with a new backlight inside. You could replace the backlight now or buy a new monitor since prices have dropped.
