Hello everyone, i'm having some issues on my laptop and i hope you could provide me with some solutions.
So the problem is, not more than a month ago, 4 keys on my keyboard started to malfunction, which are: "'(apostrophe/4)", R, F, and V. (PS. I am using On Screen keyboard to type those letters)
Sometimes they work, and sometimes they don't, unlike other keys that are working properly, I've found three components in my device manager that have error code 28 meaning there isn't a compatible driver for these components, speaking of which, they're :
I think they have something to do with the issue i'm having with my keyboard.
Another thing to keep in mind that the mechanical part is out of the question, i've emoved the keys to find any dirt or dust that keep them from working, but there wasn't any, and when the keys work (sometimes), they don't need heavy force to be applied in order for them to work.
Another thing i've noticed, is that when i hold "H", "R" and then press "F", it works but it types "Y" instead of "R", "H" or "F". And when i hold "R" and "F", then press "Back space", the result is "=". With that, i've made sure there's nothing wrong (probably) with hardware, and it's a software problem.
Thanks for reading this far, i appreciate it ! You may take a break if you feel like it.
And now onto the procedures i've tried:
PC SPECS :
TOSHIBA L50-B-1HJ
Processor: Intel(R) Core(TM) i7-4510U CPU @ 2.00GHz 2.60 GHz
RAM: 8GB DDR3
Storage: 480GB SSD
Display adaptors: AMD Radeon R7 M260
Intel(R) HD Graphics Family (4400)
Thanks for getting this far, i really appreciate it and would be thankful if i got any support that could help me fix this problem.

And now onto the procedures i've tried:
- Of course uninstalling and reinstalling the keyboard drivers, didn't work.
- Opening the laptop itself and examining the keyboard port for any dust or anything wrong with it, didn't work.
- As a last resort, if there was any malware causing the problem, i've done a clean installation o Windows 10 (Home, i had Pro before but had a license of Home so went back to it), also, didn't work.
