Okay....I bought my computer about 2 years ago, and it has a lovely 21" LCD screen. Great, right? Well....recently it has been flickering, and now it randomly turns black. It is about to do it right now, actually. I can easily fix it by turning my monitor off and on again, but was just wondering if anyone knew why this was happening and/or how to fix it? I really don't want to pay someone to look at it since its not "broken".
