Must have a CD-writer if not a DVD-writer. Just stick it on a desk or bare wooden table and get the data off the machine. It will only overheat while the processor is being heavily loaded, hence the crashes while playing games and doing graphics. While your burning CD/DVD most of the activity is in the form of disk access and the processor is lightly loaded. It should be fine for a while under those conditions. Just to be sure use a re-writable CD or DVD, depending on the drive so that if it does crash you don't waste a disk. Once you know it will work long enough to burn a disk then you can use write once disks giving it off time between burns to let the machine cool down again.

Another method if you have a stand alone machine to is to back-up over a network. If you do this you will need a wired network connection for speed. You can do it by setting up the home networking under XP.
