Windows 10: I accidentally shut down my computer during an update and now it won’t turn on

When I got off my computer at night I didn’t realize I chose the “shut down and update” options, so when my computer started to make a lot of noise I fully powered it down without thinking. The following day when I turn it on, the screen is black and nothing I have tried has done anything to change it. I still hear the fans in the computer, but I see no difference on screen. I’ve been using this dell Inspiron 15 for a couple of months now.

Windows defender is turned off and won`t turn back on

Windows defender on windows 10 enterprise won`t turn on. This happened shortly after i updated it; when I try to turn it on it says:

This app has been turned off and it isn't monitoring your computer.

And right underneath it, it says:

If you are using another app for malicious and unwanted software use Security and Maintenance to check that app`s status.

Need for a response ASAP, thanks
