i wnt on my computer today, and... its all messed up, lol. like i used it a day b4, nd it wuz fine, but today its acting wierd. the start button on the bottom isnt showin up, and none of the programs r workin, if i try to open windows media player, it says cnt open it becuz their isnt enuff memory, so i deleted a couple gb's of data nd it still wnt work, so i put da computer in safe mode, and tried to do system restore, it said computer cant do system restore, so how can i make it work.. without losing my data?
