First, is your computer a "brand" name like a dell, or gateway or something like that? If it is, look on your case for some type of model number. Usually on a sticker somewhere on the case.
If it is not one of those bigname brands, then follow this link and download this program:

It'll probe your computer and give you the info.
We need to know what your motherboard make and model is. Then you can go to the maker's homepage and find your drivers there. In particular your chipset drivers, as your computer will not function properly without them.
You will also want to check what everest says about your graphics. If you are using integrated graphics then the motherboard maker's site will have the drivers for that, but if you are using a video card we need to know the make/model of the video card as well so you can download the drivers for it.
Every part in your computer needs a driver to allow windows to work with it. Many parts' drivers are INCLUDED in windows, but many are not. When you installed windows ALL your drivers were erased.
I'm stepping away for a bit as well, but will be back shortly. If not, someone else will pick up the torch and walk you through it.
No worries, we'll get you up and running in no time. But first we need to get your CD drive working so follow that link above and see if it works.
