Minecraft screen flickering

For about two weeks now I have had flickering issues in minecraft. This started around the release of Windows 8.1. This happens in all versions of Minecraft and I can't find a fix for it. I don't know if this is my PC or Windows but here is a link to my PC specs, http://electronics.woot.com/offers/hp-envy-desktop-w-windows-8-12. A video of this is affect: https://www.youtube.com/watch?v=1QzjjM28s60. (My little brother was in the background)
Thanks for any feedback in advance.
