My laptop runs much slower and the mouse cursor flickers every second

This started occurring yesterday. My laptop (Windows 10 Pro 64 bit) was running slower than usual and the mouse cursor was constantly flickering. I checked the recently installed programs and uninstalled suspicious looking ones. I also tried restarting the system, ending Windows Explorer from Task Manager, running it again and even ran a Malwarebytes scan.

Today, I used the Reset feature from the recovery options, opting to keep personal files. All the third-party apps were uninstalled yet the problem still persists. I ran a Windows Security quick scan and found 1 threat, which was removed. But the flickering hasn't stopped and the system still runs slow. I'm out of ideas now.

UPDATE: Things almost always return to normal when I switch to tablet orientation, where the keyboard and touchpad stop working.

Here's the result:

The flickering hasn't stopped.

P.S. I can't even use shortcut keys for copy/paste (CTRL+C, etc)

I recommend you to completely repair Windows before you have to make a copy of your personal files

Microsoft Official Website to download and create Windows 10:

This solution isn't feasible as I've some work to do this weekend and I hope to manage the annoyance for the time being.

Isn't there another solution here that pinpoints the exact problem/ I want to know what went wrong because it can possibly happen again otherwise. Reinstalling Windows itself seems like an overkill to me, though I'm not an expert or anything.

Some scans from MS tools, looking into the problem more, anything that can work/ And yes, I'm unable to type a question mark with a shift key, though it works on other things (like brackets and symbols : "@&%$).

Working in spite of the problem, I discovered another interesting thing. 

My laptop is convertible to a tablet and when I rotate the LCD panel more than 180 deg (which shows the option to switch Windows to tablet mode), everything works fine! The mouse doesn't flicker, the lag vanishes instantly the moment I rotate the screen where Windows considers it a tablet orientation.

It doesn't matter if I remain in laptop mode or tablet mode, when the keyboard and touchpad stop working in this orientation, it all works okay. So I tried updating the mouse, touchpad and keypad drivers but nothing improved. 

I would prefer that I get to the bottom of this problem, instead of doing a Windows reinstall (I've backed up my files so I won't even keep my personal files when I do it).

Try to create a Local User and test if it works well.

Nothing changed with the local account. When I'm in tablet orientation, it works well. When I'm not, things get laggy and hang for 5 sec or more.
