can you provide me different instructions regarding computer hardware installations and computer parts?

This question really can't be answered. It's like trying to build a space shuttle in your garage. It's just too big a job. So let me refer you to some web sites that have a whole bunch of information on a whole bunch of computer things. They're not listed in any particular order:

And don't forget to go to your own computer manufacturer's support site for specific info about your machine. You can usually get free diagnostic scans, service manuals, updated drivers, etc. And you can always go to a library or used book store to pick up some specific titles for computer repair, networking, programming, etc.

Hope this gives you a little help.
