Strange Problem?

I just built my first pc. Everything is fine, it installed the OS perfectly and everything was running smoothly.
I then installed a load of updates and the mouse started to act strangely, whenever I clicked a button, it always seemed to click the top of the page, for instance, Whenever i clicked on the desktop the top left icon would be clicked.
I then thought it may be a dodgy install, so I reinstalled, but the problem kept happening during the install. Such as always choosing the top language and such.
I really can’t figure out what the problem is, and I don’t even have another mouse to test if this one just broke (it’s a razer diamonback, if that makes a difference).
EDIT: I just checked and it can’t be the mouse, it works just fine on my laptop.
Answer #1
What surface are you using it on? When I had my G5, I had similar problems due to it being on a surface that doesn’t work with the laser.
Answer #2
I’m using it o a wooden surface. Although it does work one the couch material as well. It’s strange though, when I log into windows now it’s fine. But soon it just starts to act weird.
