Why do you need to back up 9.5GB of information? Most of it is probably programs which you can install again from your CDs once you have reinstalled Windows XP. It's also very unlikely that installing new drivers will result in you losing your data. If it doesn't work, then go back using the System Restore and try another driver. And crashing doesn't mean you have lost your data.
If you still feel like backing up your data, just backup the most important things and files you can't be bothered to download again.
