Is there a way of backing up everything on your pc to a cd or something like that. So if had to format tommorow I could just have everything on disc?
Try Data Backup X. It's for mac, but surely there's a Windows version. Or search at VersionTracker for backup programs.
Get a program called Partition Magic. It will make a virtual HD by making a section in the HD. Then you paste all your files in it and if you have to format well you'll still have everything without having to waste time on burning a bunch of cds
