Can I really burn discs that will make my broken laptop run?

When the tech at HP told me yesterday that I am going to have to ship my laptop back to the factory to have a new motherboard installed, he mentioned that there is a website where I can download a program that will make a messed up computer work. He said something about using the disc to run the computer and being able to get online. Is there really such a thing? If there is where can I find it?
