My computer doesn't start? After you try different leads, it still doesn’t start it may need one or more parts replaced.
Windows starts but does not load properly. A device driver or attached component is corrupted or faulty. Sometimes A vital windows file can become corrupted.
Windows loads correctly but when I try to use the PC it freezes or a program does not work or it runs very slow. It may be “infected” with a program or file that needs to be removed.
