Please don't take this the wrong way, but part of the hassle (or fun for masochists) of owning a pc is the fact that it's constantly changing. Getting hold of drivers for your hardware and other stuff like applying software patches is something you will have to do sooner or later.
Don't be discouraged.
My advice would be to find a friend who knows how to download and install software and ask them how to do it. I know how to do it myself and could try to talk you through the basic process, but if you are really not sure about this sort of thing, you really need someone sitting beside you to help out the first time you do it.
Swallow your pride and ask - believe me you will only have to be shown it once, then you will have mastered the process
Hope this helps
