Don't worry about bothering me, this is what I do and I enjoy it immensely. I'm not bothered by your questions. I want you to be as comfortable as possible with what you are doing, and to understand it as well. The more you understand about what we're doing here, the more you can help yourself in the future.
I know this may sound a bit cliched, but have patience. I know this is taking a while and is annoying, but we WILL get your PC working how it should again. Were I able to sit in front of your machine this would go quicker, but this is still better than paying for a new computer or for someone to look at it in person (at least I think so, but I'm a bit of a tightwad ).
