IPhone 4 isn't working on Windows 8?

Okay, so here is my problem…
My iPhone 4 is not properly connected to my Windows 8 laptop, it's not uploading photos. It is, though, working perfectly fine in iTunes. When I plug it it (I've tried plugging it in the other usb drivers as well), the iPhone starts to charge and iTunes connects, but when I try to upload things it doesn't show up.
So I went to the Control Panel, view devices and printers, and saw that both "Apple Mobile Device USB Driver" and "iPhone" are listed under "unspecified". Those are the only ones that are unspecified. The "iPhone" is the only one with a yellow triangle and exclamation mark next to it, but I assume they are connected.
When I click on the "Apple Mobile Device USB Driver" > Hardware, it says its status is "This device is not working properly". Then I go to the "iPhone".
It says that there's a "device error" and it "needs troubleshooting". The Device Status is "This device is not working properly because Windows can't load the drivers required for this device. (Code 31)".
I tried troubleshooting the "iPhone" and it says "there's a problem with the driver for MTP USB Device. Re-installing the driver might fix the problem". So I click "Apply this fix" and it comes back with "MTP USB Device has a driver problem" - not fixed.
I'm probably the most uncomputer savvy there's, so I would be 123456% grateful if anyone could try to help me. I will post pictures along with this. Thank you! <3IPhone 4 isn t working on Windows 8

Creating a chat app using parse?

How to make yourself get up when your alarm goes off?

When school starts back, I set my alarm on my phone. When my alarm goes off in the morning it wakes me up and I turn it off, but go back to sleep. I think this is because on the iPhone all you have to do is slide the screen to turn it off, but it doesn't make me get up. Any tips would be appreciated.

Can I activate an iPhone with a non working SIM Card?

I have an old iPhone that will be shipped off to another country soon, an iPhone 5 to be exact. Currently it is locked onto AT&T. It hasn't been used since I upgraded my phone months ago and has been reset to factory default settings and disactivated. In order for it to be activated and then unlocked for use in the country I'm sending it to, a SIM card must be inserted to complete the initial activation process. I still have the Nano SIM I used when it was my everyday phone, but it no longer works since the upgrade. Will this disactivated SIM card still activate my old iPhone? I don't want to try it until I'm sure as I'm not the best with phones and I've heard stories of people permanently locking their phones during the activation process.

If I reset my data usage statistics on my iPhone will I get charged?

Alright so I realized I went over my data usage by 1 gigabyte so I started exploring around the cellular data options and whatnot and came across the reset statistics. I clicked on it to see what it was and it reset everything. Obviously I know that resetting it means it'll all be at zero. Will I get charged or anything? This might sound like a stupid question but
Please help me. What's the actual point of resetting the statistics?

How do upload previously synced photos from iPhone to iPhoto?

I have about 5 albums in my iPhone that I want to sync to my new Macbook Pro. I had previously synced albums from my OLD Macbook Pro to my phone knowing I would be getting a new one and thought I could sync those to the new laptop. I'm able to sync my camera roll but that's it! I have about 2,000 other photos I need to somehow get on this computer, and then delete from my iPhone for storage purposes.

So, how do I upload photos that were synced TO my iPhone from old laptop TO my NEW Macbook?

Any help is greatly appreciated! I need these off my phone and on the laptop.
