PC doesn't recognise External HDD

[Inspirational]

Hello, my external/portable hard drive is no longer recognised by my PC. I have tried to move it around different USB slots but none of them work. I tested the hard drive on my laptop and it DOES work on it. So I think something went wrong with the external hard drive's drivers on my PC. Maybe it got corrupt. 
Is there any way I can update or fix my drivers (or the issue in general if my analysis is wrong)?

Extra Info on External HDD:
- Toshiba
- P/N: HDTP210AK3AA
- DTP210
- 1TB
 

EDIT:
Some context:
I recently tried to install software for my PS4 controller (so it works on PC - it turns out that it doesnt need software for that, my bad for not trying it before )  but I believe that while it was installing the drivers, it somehow messed up my External HDDs ability to connect to my PC. It could also be a coincidence so I dont know

I have two existing HDDs: 1 SSD, and one HDD which I think are showing up in Disk Drives.
However, the Toshiba doesnt seem to appear there, unless the libusbK thing is it

System restore points are all after the issue, so I can't do that either

Added notes: 
The external hdd doesn't appear on diskpart.exe & Disk Management

I can't find any solutions for this online either as all the f*king tutorials assume that it does appear there.

Just a reminder that the external hdd still works on my laptop. Just not my PC. I am almost certain that its some sort of a driver issue, but Toshiba doesnt appear to offer any drivers (at least for my model) [https://storage.toshiba.com/consumer-hdd/support/product?model=HDTP210XK3AA] 

I really want to avoid formatting my PC, please help

There were some real issues with this, but it was solved.

First thing was that I attempted to fix any corruption with the windows files which were found and fixed, but that didn't fix the problem. So I wanted to format, but now I kept getting an error. So I put windows onto a USB, booted from USB, formated the drive from the Windows on the USB and reinstalled it onto the drive through there too. 

Everything is now back online.
