Problem after installing 8.1

[Bramill]

Hi I recently installed windows 8.1 and I'm getting this problem where the screen just starts flashing like crazy. It doesn't happen too often. It always happens just after I boot up, but never in games. I've tried uninstalling my GPU drivers using guru3d in safe mode and redownloading them fresh and installing to no avail.

Here's a video of the problem

My GPU isn't overclocked, i'm going to uninstall the chipset drivers and reinstall them now.
