When I deleted the programs related to the buffalo ministation my windows 7 computer crashed. I used the system repair disc and then I ran the system repair, system restore, system image recovery, windows memory diagnostic and now all I have left is the windows\system32\cmd.exe prompt. I am trying to learn how to do needed repairs. I am new to this and want to learn how restore this computer. This is a Sony Vaio running Windows 7 Premium; Microsoft Windows Version 6.1.7600. It is actually fun learning about this part of the 'life' of computers.
