Does it ask you to activate or restore it?
1. Did you hold the power on button (on i4) for a little longer? Try it, because it needs to know you really want to turn it on.
2. From your picture, I do not see iTunes on your desktop. Did you install it?
3. What you see means you need to connect i4 to your pc with iTunes turned on. Just ignore the load driver message from windows, since i4 is seen as a new device.
have you tried on another Computer?Does it ask you to activate or restore it?
no it doesn't, when i connect to my laptop the picture i have attached comes up, and when i click 'locate and install driver' it doesn't find anything.
