Just a suggestion for Tool and Reaper, both you guys need to look into using Norton Ghost, and partitioning your harddrives so you don't lose everything when you reformat.
You partition your drive to have a C and a D drive (or more if you wish, personally I have one drive partitioned 4 ways), about 25gig for C and the rest for D.
Install JUST Windows and your standard apps to the C drive, install all games (and programs you DON'T want to lose) to the D drive. Save all conversion work to the D drive so you don't lose it.
Install windows clean, no drivers, run Ghost. It creates a full image of the windows installation, or you can create a ghost of Windows with full drivers and programs/apps/games installed, and you can be back up and running within 10 minutes tops.
Just 10 minutes and an easy restore, or hours of hairpulling madness to reinstall Windows plus all drivers, plus apps, plus games.
