I want to reuse my current HDD in a new build (first build) with a new motherboard. will plugging in the hard drive as is be ok or will I have to wipe it and then reinstall everything after is is properly synced to the new system? If I have to wipe it, is there any way to save the OS (windows 7) and programs like Microsoft word? Or will I have to buy all that stuff new. Also should note that the pc I will be taking the HDD from is a stock hp pavilion desktop with pre-installed OS. Thanks for the help!
