Well i use win 7. So my advice will probably be useless. Try restarting your computer. Or you can try re installing win 8.
I had to switch back as it caused too many problems with my computer. It made my graphics card stop working. Hope you find and solution and have better luck than me. x
Yes, getting a Mac fixed those types of problems and more!
Yeah switch windows 7 :/ or better yet linux
Enjoy using a terrible OS
Go back to Windows XP?
