Just today my computer began randomly putting in random symbols whilst typing, mostly this symbol ]. Also it will randomly scroll web pages up and down. What is going on?

My keyboard is brand new. Bought it a few days ago. I also thought this was the problem, but I turned it off and the same things happened.
 
The normal way to diagnose whether or not a component is working properly is to take the suspected misbehaving component out and replace it with a known working model. So if you disconnect the suspected non working KB and connect a known working one..... then,

a) If problem disappears, the original KB is boinky
b) If the problem remains, the original KB is not the problem.
