after the last patch i now cant change my graphics, (gamma or the two sliders above) without the screen turning all white ,from the options on the clipboard. The first time i moved the gamma slider just a little, hit ok and poof- screen went all white. Well after doing a system restore,i logged on and white screen gone but i still needed to change my settings so this time i hit defalt settings and poof- screen went all white , i can almost see some of the clipboard but not enough to do anything,cant see mouse pointer either. Did another restore- logged on game- and this time the screen is all white right from the start. well now what do i do ? Never had this problem before the last patch. Any help would be great thanks.
