I'd recommend you to restore your system/reinstall windows. That's really fast, you'll just needto back up your data on cds or external drive.
I'd recommend you to have this drive, so you can restore your system weekly
IOGearŪ 80GB 2.5" Combo ION? Drive for notebook
or
IOGearŪ 250GB Combo ION? Drive for desktop pc (heavy)
both are connected via Firewire / USB 2.0. IOGear makes cool hardware
