Re: non responding keyboard and mouse
Although it could be as simple as replacing the keyboard and mouse, it sounds like you have more issues than just that. Something else could be on your computer, which could be causing the issue. I would try a different keyboard and mouse (ask to borrow before you buy one). Also, are these devices USB, or PS2? If they're USB, it could be an issue with the USB controller. If not, and they are PS2, try the first suggestion.
