Computer screen went black and won't do anything?

My girlfriend went to plug in her iPhone to the computer and says the screen just went black. The power light is on and if you plug it in it has another light that turns on and both work perfectly fine. This computer is fairly new and hasn't shown any signs of issues, especially like this. How do we fix this? Preferably without taking it in and spending a small fortune on repairs.

I want to downgrade from iOS 7.1 to iOS 6 on iPhone 4 but I have problems. Read Description?

I have an iPhone 4 that I updated to iOS 7.1 from iOS 6 but the iPhone has become laggy and slow. Now I want to downgrade it to iOS 6. All the methods on downgrading require iTunes 11.0.5 or older such as iTunes 10.7 but when I connect it to these versions of iTunes it gives an error that "iPhone requires iTunes 11.1 or later. Go to apple and download the iTunes" so I can't use these methods. Can anyone tell how to downgrade using the iTunes 11.1 or later (newer)? Or how to make the iPhone 4 work with iTunes 11.0.5 or older so that I can use the old methods that are present on google? What should I do?
