Very important to back up or at least copy and paste your already downloaded programs from your old hard drive to a USB or larger external drive. I was so upset that the control strip/mobility center would not light up and respond once everything thing else seemed to be working properly. I'd been going at it for weeks trying to figure it out. Today I started copying and pasting all the items I wanted to save from the old hard drive to put on my new hard drive after I restored it to factory default and reinstalled Win 7, plus drivers. (something that was probably unnecessary had I just tried copying and pasting the old files to the new hard drive. Who knew they were missing) (I had tried uninstalling the Audio Drivers and Quickset but, that just made the computer boot in Safe Mode with Networking, where I couldn't backup and restore to usb or CD) Lo and behold when I got to the "program files" and program files (x86) everything came on, finally!
