Windows 10: Had to share a GINORMOUS WTF JUST HAPPENED

The issue has resolved itself but if anyone has a clue what happened based on the description -- I'm all ears. I have a Lenovo that acts as a kitchen TV. Last night I was streaming THE OFFICE off of an admittedly 'risky' site. (This laptop is 'expendable' in that there's no critical data stored on it.) While my wife and I were eating she spilled some water. My mouse and mousepad were on the table. In her efforts to save them she knocked the mouse onto the floor. When I got it back -- the PC was half unresponsive. 1. There were no funny windows open. (Like the fallen mouse triggered something.) 2. I couldn't click half of anything on the screen. Right click was dead. 3. GET THIS -- I managed to get Powershell open for an SFC but it informed me I was no longer admin. 4. A forced reboot didn't fix shinola. 5. Turning off the wireless mouse, unplugging the usb dongle? Nada. 6. I plugged a wired mouse. Nada. 7 Since my wife has used Windows way longer than me, she asked if I had tried CONTROL ALT DELETE. (I almost never need to.) That kinda freed things up a bit. 8. There's a recommended Firefox plugin I had set to inactive. It's called Video Downloader. I removed it. (I find this plugin is best and on/off thing. Install, use if you must, then get rid of it.) That maybe helped. 9. Long Defender scan and Malwarebytes reported no problem. 10. There was a Cumulative update available. But not already in progress when I discovered it. So here's the basic question -- what are the odds of that plugin doing something nefarious JUST as the mouse drop happened? To me extremely low. But, then, the odds that the mouse caused all this seems ten times crazier to me.

WTF just happened?!


Why won't this work?

 

WTF just happened?!


The setup screens are hosed! It went from saying it's an AMD process to INTEL! I cant even comprehend how an AMD cpu can run with bios being set to Intel.

 

Cannot access shared network drive

I could scream! so much time wasted on this stupid error, as if time is not precious enough!
It probably would work fine if I could see the other computer! But I cannot see the other computer!
