I'm having an issue I can't seem to find anyone else having with Windows 8. After I boot my PC and I'm on the desktop, my computer is super stuttery for about 5 minutes. I don't use low end hardware, I run a i7 2700k, 16GB DDR3 memory, 256GB Samsung 830 SSD, and a radeon HD 6850. My mouse doesn't scroll near as smooth (which I can't stand) and my sound is scratchy and slowed down to probably 3 or 4 times the normal length of sounds, and it's also delayed. Anyone have any clue what might be going on here?
