7 Black bars in the middle of my screen

[Tweeoo]

I have a Lenovo Y700 laptop with:
I7 6700HQ
GTX 960m w/4GB GDDR5
16GB DDR4 RAM
Windows 10

and from time to time when I open it up and wake it from sleep mode, I have 7 black bars on my screen. They take priority and overlay anything that's open. I've found that simply logging out of my account will solve the problem. I've also noticed that when I hover my mouse over them, I can see my cursor over the bars rather than behind (like it does with anything else). The last thing I've noticed about them is that when I right click them anywhere, there's no menu that comes up which makes me think it's some kind of program that went all haywire when I put my laptop to sleep. I'm pretty stumped at this point, mostly because I can't even find unsolved reports of this problem anywhere. Here's a screenshot of my desktop, the black bars are just a little bit to the right and down from the center of the screen.

Hi,

What monitor is it?
It could perhaps be the monitor itself causing this strange behavior?
Try to shut down only the monitor via its power button and power it on again, just to see if it change.

It's part of the laptop, the only description of it from Lenovo is "Ultra HD (3840 x 2160) 16:9" and in my device manage it's simply listed as "Generic PnP Monitor"

Try to install the latest nVidia graphics driver and then restart http://www.nvidia.com/download/driverResults.aspx/102999/en-us
It is for your graphics and Windows 10 - 64 bit

Then go to Lenovos support site and download and install all other latest drivers - except the graphics driver.
Restart.

Seems that all my drivers were up to date besides an audio driver. I updated it and restarted. Unfortunately, since I don't know what causes it, it'll be hard to get immediate results on whether or not it's fixed. Either way, I'll keep this post updated if I find out more, until then feel free to keep throwing ideas at me.
