Tried plugging in my iPhone 4 to my computer?

Hi, so I plugged in my iPhone 4 into my Acer (windows 8) computer on all three USB holes and none of them is pulling up my iPhone file on the My Computer's file. I tried going on Control Pannel > Hardware and Sound > Device and Printers and troubleshooting the iPhone but it doesn't work. Any ideas or input?

Make sure iTunes in installed.

Try:
1. Update iTunes
2. Check the USB cable
3. Verify that Apple Mobile Device Support is installed
4. Restart the Apple Mobile Device Service
5. Verify that the Apple Mobile Device USB Driver is installed
6. Check for third-party software conflicts

  • Plugging your iPhone into a different computer? I have an iPhone 4 but I need to update the software on it but obviously I need to do that from iTunes. My problem is that the laptop I normally connect it to is all slow so it takes me like half an hour to switch it on. I wanted to know if I download iTunes on another laptop and connect my phone to it, would it wipe my songs and apps? If so, how do I stop that from happening?
