I don't recall where I saw it mentioned. There is a program that will read your computer and extract all the registeration keys for you. Then as long as you have the program CD you can reistall it.

Xp offers the transfer wizard. I have never used it for programs. I do think it will transfer them over. I do think you will need a little more than 30G for the transfer file data.

At 6 years old I would have to agree that a new computer might be your best option.

Edit: A defective driver, failing power supply, bad memory, failing HD or a loose connection on the MB are the most common causes of rebooting. Scan the hard drive and then test them in the order listed.
