My swift 3- pg dn button keeps spamming. Swift SF314-512

I've had this swift 3 for almost 3 years now. And in the last few months or so i have been experiencing this problem, where I can be using the laptop fine. Then suddenly my pg dn key will be spammed. The only way for it to stop is for me to literally run my finger over other keys. Then it happens again a moment later. Sometimes it would boot with the key already being spammed. I dont have a dedicated pg dn key, so my function key gets pressed with it too which is even more bizarre.

As you can imagine I cant get much done like this.

I have reset windows, booted in safe mode (still persisted), uninstalled my drivers. These options aren't working, ran anti virus, both windows security and malwarebytes. But the problem persists.

I would be grateful for any help. THANK YOU.

Change the upper case and keyboard as it could be a cable fault or the keyboard pg/dn key of your SF314-512, laptop, as that is where the fault is. Don't know which country you are in, as there many language version keyboards for the SF314-512 laptop, give us the language that you require and we will give you the correct upper case and keyboard for your laptop.

DO NOT buy just the keyboard for the SF314-512 laptop as these keyboards are riveted together to the upper case and can't be changed and if you attempt changing the keyboard you will destroy the upper case. Good luck and hope this helps you out.
