Windows 10: White bar at the top of screen

I'm having a white bar at the top of my screen for the past three months with two monitors connected to my PC. Ctrl + Shift + Win + B doesn't help anymore. I've tested my computer's RAM and found errors, therefore replaced the RAM with a new one. After that I reinstalled OS Windows 10 Pro x64. I set "Scale Full Screen" option in Intel HD Graphics control panel and because that didn't help either I added a new graphics card AMD Radeon R7 200 Series and connected both monitors to it. So far nothing helped. Can someone give me any idea on what to try next?

Chrome---lots of white space at top of screen

Not exactly sure how to word this. When I go to Chrome, this is what I see, from top to bottom:

1. Tabs at very top.
2. Address bar.
3. Below address bar, huge amount of white space, then a line.
4. Content.

The huge white space takes up precious screen space. I want to get rid of it. At one point, Chrome/Google had some stuff there, which I deleted. But I cannot find a way to remove the white space. This wasn't there when I was running Windows 7 two weeks ago.
Now I am running Windows 10.

Thanks.
