Microsoft makes the world's worst operating system that isn't compatible with anything, and before they even begin to fix all the bugs in it out comes Windows 8. Fail. Don't worry though. If you have Window's 7 I am here to provide tech support for you. What I've found helps with many of the issues is to a smash burn on the system to clear out any bad files. First shutdown the computer. Next open it up and continue to pour lighter fluid on all the parts. Now toss a lit match in there along with some old newspaper. (It helps to be in a tall building for the next step) Throw out window. That should do it.
