|I never heard of a Dirty install and not sure if I want to. Save your files (use Live Linux disk to access the hard drive to save files), gather install disks, download up to date system drivers to a flash drive, Download other installers to flash drive as well, and do it right (the more prep ahead of time the easier it will be). If the hardware is all good then this will be easy and less trouble later. Do clean install (custom, partition/format, delete any old partitions and create new and format), then install drivers, then install all Windows updates - SP1 first if needed (may take more than once), then install antivirus and update it, then install programs and finally your files.|
You have to be a little bit crazy to keep you from going insane.
