Hey there.

I quickly read over your post and saw something interesting.
The bit: "Invalid Drive Specification. It won't let me create a path to Drive C." is similar to my problem. Does your command line say a:\> ?

I'm sorry, I can't help you with your problem, but sites such as:

Thetechguys - www.thetechguys.com
Copmuterhope - www.computerhope.com
Help Site - help-site.com

Are all VERY useful.
Just google "pc help" or a description of your problem and you are sure to see people with the same results.

Anyway, good luck on fixing your PC.
