1.i do not know why i cant get on Microsoft.com but i know non of the computers at my house can
Sorry, let me rephrase the question. What is the browser doing when you try to go to Microsoft.com? Is there an error message? Are you redirected elsewhere?
The inability to access Microsoft.com (as well as many anti-virus sites) can be an indication of a virus on your computer. Are you computers running AV software, and if so what AV software are you using?
2. my uncle who gave me the computer
I mean no offense to your uncle, but this advice is wrong. You want to go to the hardware manufacturer's website to get the driver specific to their hardware.
3.i don't know the computer is a hammy down from my uncle and i don't think he still has the box. If that is something i could find out with out the box and just form the computer its self with out opening it i will find out and tell you.
4. again but i would guess somethings built in because it beeps for windows messenger
We'll need to figure out some model numbers if we're going to be able to find you the right drivers. Look around the outside of the system for a brand name and model number. If you can't find one, it's possible that it's a custom built system.
If the case doesn't have a model number, we can try something else first if you'd rather not open the system. Download
Speccy. This software is free and safe. Install then run Speccy.
Speccy's interface is quite simple. Give it a moment to analyze your system, then it should tell you on the main screen the make and model of your motherboard as well as what audio device is currently enabled. (see thumbnail below)
