You need root to fix any of the problems, but you won't be able to root it without connection to computer.
Try to re-install samsung usb drivers. Uninstall kies first if you got it installed.
Reboot computer, open odin as admin, turn the phone in download mode and connect to usb.
Try different ports if it doesn't get detected. Try another cable.
