hmmm..... seeing you're posing on this fourm, you obviously have another computer....so in the mean time, is it possible you bring your computer to a nearby store or something and see if they can find out what's wrong. They might say 'come back in a week' or maybe less but at least you can have 'professionals' look at your computer and find out what's wrong.
This might cost a bit of money but seeing how desperate you seem to be, i think it's worth it......
