Keyboard key is randomly triggered

[Hampen]

This started to randomly happen today, and I have never had any issues similar to this before. I havent installed anything today, only thing I have done in that regard is updating Razer Synapse.

The key being triggered is Page Up. I know that's the one because I ran the macro recording feature in Razer Synapse. I have also disabled that button in Razer Synapse, so I doubt it's a keyboard issue, or is it still possible? I have had this Razer BlackWidow Chroma since 2014, so its quite possible that it's at fault since it's been with me for 3 years now. I also ran a stopwatch to see if it's triggered once a minute or something like that, but it seems to be very random.

This is what I have tried so far:

• 
  ■ Restarted PC
  ■ Closed Razer Synapse
  ■ Disabled the key in Razer Synapse
  ■ Ran a virus Scan

Would be very happy if someone could help me figure this out

did you look through synapse options to see if they added a function to it?

did you check if new firmware for keyboard? Have you cleaned it recently? (I had a blackwidow until the W key stopped working on it)

try a clean boot and see if it still happens - this would show if its a start up program at fault: https://support.microsoft.com/en-au/help/929135/how-to-perform-a-clean-boot-in-windows - slowly re add them to find cause.
