The last update ruined my dual monitor set up. As soon as the update had finished my second monitor stopped working completely. Restarting the computer will sometimes allow it to work for a few minutes, but the resolution is stuck between 800x600 and 1024x768. I've tried restarting, updating all drivers, deleting and reinstalling drivers and so on.

I use windows 10 x64
geforce 960x
intel dz77ga-70k motherboard
intel(r) core(tm) i5-3570k cpu @ 3.40ghz
