This week I upgraded my CPU (FX-4100) to FX-8320 and my motherboard (Gigabyte GA-M68MT-S2) to ASRock 990FX Extreme3, and was wondering how I would properly reinstall Windows 7. I have Windows 7 on my HDD still with some fairly important files on there, so I don't want to wipe or format it. How would I go about reinstalling Windows without disrupting those files, or on top of my current install? I've heard that I can do it a certain way (not sure) that will keep my old files under windows.old or something like that. Any help would greatly be appreciated! Thanks!
