Интернет Connecting to the

I had someone set up my server, but we had в falling out and that's не longer an option. My computer can't even seem to detect my мышь and it says it can't connect to the Интернет. I can't do my blogs or upload my podcast until I get this веб сайт working again. I also don't really know anything about computers at the highly technical level. What do I do?
