Compaq Presario CQ57 won't recognize iPhone 4?

When i plug my iphone 4 into my compaq laptop it makes a noise but doesn't actually connect. I called tech support but they didn't help and i called apple and they couldnt help. It used to connect but now it doesn't. I think something is wrong with my laptop and not my iphone. How can i connect it so i can't transfer my pictures to my laptop

Okay Look.
I have a few stuff that might be the cause:

1. Your Laptop Is too Old So the Iphone Doesn't support It's USB (Or Vice Versa)

2. Your Laptop Is Overloaded with stuff, try and clean it up to free up some RAM.

3. You Might Of Brocken the USB, Check it out to see If it Has Scratches/Bumps on it.

Take Both Of Them To a Hardware store repairman, he might have a better solution for you

You should factory restore your Compaq to make it run like new by restarting the computer and pressing F11 consistently long before it attempts to load windows so that a Factory Restore program will load and you can restore the computer to the condition that it was when you first bought it! Just make sure you save something important in advance before you do this!

  • Why won't my laptop recognize my iphone? I've used the usb to charge it from the wall and it works perfectly fine but now i'm trying to update my songs so i tried plugging it into my laptop and connect to itunes but it doesn't recognize my phone or show up that its charging (i'm using the same usb)
  • Why won't my new computer recognize that my iPhone is plugged in? I recently got a new computer, but all of my information for my iPhone is on my old computer. When I plug up my iPhone to my computer, it doesn't register that it is plugged in. Nothing is wrong with my charger and nothing is wrong with my computer. I don't know what to do to get my information from my iPhone onto my new computer and to my iTunes.
  • Why won't my computer recognize the music on my iPhone? I can play the music on my iPhone, and I want to update my phone but not lose my music. Some of it was not purchased on iTunes, but I have used programs that transfer music to computer without the help of iTunes, and they don't recognize my music either! ITunes won't even recognize the music i have purchased from the iTunes store. I want to restore my iphone and thats why i need to get my music onto my computer. It is an iphone 4s running on 5.0.1.
  • My iPhone won't recognize my home Wi-Fi? For some reason my phone doesn't connect to my home Wi-Fi anymore. When I go to settings it doesn't list any connections available for me to connect to. Is there any easy way to fix this problem? I really don't want to and don't know how to mess with my Wi-Fi router or whatever it's called.
