First off, i know nothing about computers, and just found this sight trying to find a helpful website to look at. I think this is a pretty basic question. My computer just lost all its memory. I can barely run anything. I tried to defrag it, and it showed that all files were fragmented and there wasn't enough memory to do the defrag. I figured i could just formate the computer and just start all over. I tried that through msdos and i couldn't figure it out. Can someone help me out? Thanks alot.
