Hi,

This is the DH. Don't reformat and reinstall your operating system unless you have everything backed up from your hard-drive, as you would loose it. If that's not an option, you can install a new second hard drive and have that be your boot primary drive and the original drive would be storage. A clean disk just seems to run and operate much smoother and faster. That said, it still might not be worth doing. If you can run defrag and disk cleanup that will help. Deleting stuff you don't use will help, and more memory should help. Good luck.

P.S. if you end up looking at a new computer, you might check out a MAC, there are a few hiccups coming from a PC, but I'm sold...
