Kinda of hard to explain but... When I plug my iphone into my computer it is detected, charges, and is recognized by iTunes for a few secs, and then becomes undetected/unrecognized for a split second before working again, repeating this cycle indefinitely. iTunes gives an error message of, "an iphone has been detected but is not recognized.." multiple times in a row. Things I've tried: Disconnecting the phone and plugging it in again Restarting PC Restarting Iphone Trying a different USB cable Re-installing iTunes Re-installing the iPhone driver Notes: Other USB devices work fine with the ports on this computer. I've tried connecting 2 other iPhones to this computer, they all give the same error. My iPhone works fine when connected to my other computer. Specs: iPhone 4S, 7.1(?) / iPhone 4S 8.3 Alienware 17 R4, Windows 8.1 Any help would be GREATLY appreciated!
