    Last night my computer screen started flickering, it kept on flickering getting lighter and darker every flicker(just by a little bit).It also made a noise kinda like when you see light bulbs in horror movies flickering on and off. So my brother said to turn off the screen and I did. when i get back from school it stopped flickering. I went outside for a few hours and came back in to find it flickering again. what should I do?

    Check and see if your monitor is still in warranty. Usually they have more than one year from the manufacturer.

    This is a flat panel LCD display, not a CRT, right? LCD monitors use fluorescent lamps as the backlight (unless it's an LED backlit monitor), and they eventually burn out and flicker just like the ones in grocery stores and horror movies.

    If that is what's going on, you will either have to replace the lamp or replace the monitor.

    If it does it connected to another computer, it's fucked. You'll need to find somebody that can fix it IRL.

    That's not what Rydian meant. He meant that if you connect it to a different computer and it still does this than it is the monitor, not your computer.

    If it's the monitor, it'll happen no matter what computer you plug it into. In that case, it's probably the backlight as mentioned above.

    If it's the graphics card (or just the cable) then it'll prolly be fixed when you plug it into another computer. That implies bad shielding or dirty/broken pins. Personally, I think it's the monitor.

    It's possibly magnetic interferance. I've seen it happen. Take it over to a buddy's house, in a different house. That way you can test both where the problem lies AND if you are receiving interefance.

    Alternatively, you can take a laptop and plug the monitor outside your house or something crazy like that.

    If it happens then it comes good again after you leave it off.
    You just need to take the back off of the monitor and look at the power supply and check for bulgeing caps. http://www.eventlogblog.com/blog/2008/01/18/Bad.jpg if they look like this then thats your problem!
