Why won't my Iphone4s connect to my laptop?

We were required to make a tutorial on a topic in Math, so I used my phone since my groupmates didn't have a camcorder. And all my videos are in my phone. And now I can't connect my iphone to my laptop! It just makes this sound and whenever it does my phone charges for a second and then doesn't. In my iphone's screen it keeps on saying if I trust this computer or not, and it just pops out in a second and I can't even press trust. I just bought a new USB cable since I thought my old one was destroyed. My Laptop is in Windows 8. Is the problem in my phone, laptop or USB cable?

Do you have itunes?

Reinstall Itunes if it didn't help then reset your iphone
go to general>reset>reset all settings. It will not erase anything.
kind of i had same problem

  • Why won't my iphone 4 connect by usb on my laptop? I have a toshiba satellite laptop on windows 8, I've tried to connect my iphone up to my laptop so that I can connect it to iTunes but every time I try to connect it up it connects for a second gets to the charging screen for a second and disconnects again and does that over and over again.

  • Why won't My sprint iPhone 4 won't connect to 3G? Before you say call them I already have ok. Today I had an upgrade but my aunt used it for her phone since I'm on her plan. It went good but then won't connect to 3G after that we called and they said something went wrong but nothing did so I'm wondering is there anything i could possibly do to fix it or should I call the place that did it? Or should I just call sprint or apple? Please help I have to use my phone a lot in places that don't have Wi-Fi.
