I have a very old computer that was just given to me. I was trying to find solitaire or someother game and opened ms dos instead. I wrote something in the command area and closed it. Now everytime i turn on and off the computer it will go to a different screen asking the for the right command to override safe mode (because my computer turns on to safe mode). The only way I am able to by pass this screen is to press F5 and it will take me to the general computer items but it will not allow me to play cd’s or any other type of audio. What should I do?
