Scene view not responding

I have my windows update set to automatic (which I have now changed after this) and the only thing that has changed since my last time working in unity is the latest windows update. I’m running unity 5.2.2, and everything was working fine last time I used it. Now, the scene view does not display anything but a blank screen. I open a new scene tab, and then it does render, but then it does not respond to any input, i.e. mouse clicks, I cannot even move the tab, or pull up the tab menu. I have a lot of work done in my project and do not want to lose any of it. Please help with this issue, as I cannot fathom what would have gone wrong.
P.S. I also tried using system restore to go back to before the update, but it fails when it tries to revert the old settings, and will not allow me to go to a restore point further back.

Thanks to Mavina. This seems to be working the best of everything I’ve tried.
