if you always want to reinstall everything when a problem occurs,
think then at the option of remastering (search for "remaster" on the forum to find more tips).....
The most simple way is open a Konsole, log in as root (type su and fill in your root-passwd), and then type uname -a [ENTER] (unmounting all unneccessary partitions, then type remasterme [ENTER] to make an ISO (which you can find in /root)
But that only works if the data in your root-partition AND your home-partition are less than (or maybe equal to) 12 Gigs.........
=> like this, after you installed and configured everything, you can make such an ISO (maybe even every week, but remember to MOVE it to a back-up place, so that with a later remaster it don't fill up space), and use later if your system is broken-up.......
(you can put it then on CD, or on an USB-flashdrive with UnetBootin)...
