OP, one of the challenges here is that you haven't provided people any information about anything whatsoever. All we've been told is that you have some computer, on which you did something, and then something happened and there's a burning smell.
Until you provide a complete list of your specs, a step-by-step of what you were trying to do and what you did do, and a detailed description of what's going on, there's just about no chance that anyone can provide anything resembling useful advice. Nobody here is psychic; all we know about your situation is what you tell us.
