Inspiron 3847, Bios update frozen?

My Dell Support Assistant prompted me into updating my Bios, it started doing what it should be then froze.

I am here.

It doesnt seem to be going any further. The PC still seems to work Ok however I fear that rebooting it may not be a good idea. Is there a problem here? Can it be fixed? Any help would be greatly appreciated.

I wont shut down the Pc until I hear back.
