So I finally got the solution to my tablet randomly shutting down.
Took me 2 months >_>.
The problem was that the Wacom Tablet Drivers tend to shut down randomly.
I would give the link where I found the solution but I can't find it anymore.
If anybody comes across it, please post it here so I can still give credit to the real hero!
(the website had a dark background, it reminded me of outerspace ^^')
Your tablet shut down! What now?
No need to restart the laptop/computer.
You just have to restart the drivers, because you can restart a single driver!
I never knew you could do that O:!
Just search for "service.exe" on your laptop/computer.
You'll see a list of all kinds of stuff on your laptop.
Search for your Wacom driver (press w to move to all the files starting with 'w').
Right click them all and select "Restart".
Also search for the file "Tablet PC Input Service". I always restart that one as well just to be safe.
And your driver isn't a little beach anymore
