I have a acer S2 Series 23" Widescreen Flat-Panel LED Monitor ( http://www.bestbuy.com/site/Acer+-+S2+Series+23%22+Wide... ). I bought it about two months ago and have had no problems up to now. Starting last night, when ever I would watch videos on it, it would blink, just once, like it was getting ready to play the video. Once I closed the window with the video, it would do it again. Before this happened last night, I downloaded a driver update for my graphics card, a GTX 560 ti ( http://www.newegg.com/Product/Product.aspx?Item=N82E168... ) . I feel like that probably is the problem, but I don't know what to do to fix it. Any help or suggestions would be appreciated.
