I don't see any way how anybody here can help you to fix it. Not only is it outside the parameters of this forum, which is concerned primarily with Windows 7, there is no sensible way to troubleshoot old stuff like that "from afar". In order to experiment with gear like that you need to know exactly what you are doing, you need to research very carefully in order to get compatible parts, you need the test equipment and software to test things, and most of the time you will still end up with an outdated, unreliable, and less than stellar performing machine.
Basically, it is just not worth it. Practically any trained technician will tell you to throw it in the recycle bin, and most of them would do likewise. There is a point in all these things beyond which it is simply not sensible to go.
