Need advanced mouse troubleshooting?

[989]

So, i'm unaware as to what could possibly causing this, as well as how to describe it.
I've run AVG PC tuneup, which always fixes the problems i can't solve myself, however, the issue persists. I've updated my drivers, my browsers, and my games, yet it persists.I'm running windows 8, on an HP pavillion laptop. I got it a few days ago, a bit over a week, and I don't think i want to bring it in on a store warranty so soon. It seems silly to bring it in for an issue like this. Now, onto the issue: I am not sure how to describe, so i'll simply describe some of the symptoms i've seen. Firstly, on google chrome, i can not type in the address bar, at all. When I mouse over it, there is no response. I've updated chrome and all, and at first i thought it was just chrome, as other browsers seem to be working fine. Another common problem that has occurred ffrom this error is when i try to open minecraft, my mouse will hover over, and highlight the launch links, but not be able to execute anything. This problem persists in similar launchers and flash animations. My next issue: When i can get into games, at some point or another, the mouse will suddenly appear on screen, and next time I have to click, it will simply exit out of the game. I will alt-tab into another window, and it will be open until I click anywhere in the window, at which point it will close. One last common symptom: when I can navigate through google chrome, and i want to switch tabs, the tab I click on closes. These are minor inconveniences, but solving them is no less important to me than if my motherboard mysteriously died. I'm sorry I couldn't be more specific, or get to the point, i'm just puzzled at what this could possibly be.
Whatever it may be, the problem is almost definitely with my cursor, and not with the USB mouse I use.
