Thanks for the reply. Since I recently reset my computer, there are no unnecessary programs as I only installed the ones I need. I see where you're coming from with the slow typing - there is nothing unnecessary open on my PC, and the reason why I don't believe this is an issue is because how the typing is fine, then randomly is triggered while doing something. Although it is a possibility that something is opening which triggers this, so I will look into it.
In the device manager there is no orange triangle. The keyboards listed are 3 HIDs. I have a feeling that it could be Corsair Utility Manager that is causing the problem because it is always open for my keyboard and mouse. I shall get back to you when I try removing this. If you think of anything else I could try let me know.
