I plug it in and it charges to my computer to Zune doesn't open and when I open Zune individually it says connect your device.
Do you hear the usual USB connection chime when physically connecting the phone to the PC? Going by your description, your PC isn't aware that the phone is connected to it. I know you said you "rebooted" Zune, but did you reboot the PC itself? How about powering off the phone, removing the battery, and powering it back on?
