Drops

So I'm afraid that my computer is acting funny. We'll see how often it happens or if it's just a dirt issue, but my keyboard started going on the fritz a little while ago. I would be typing in a text box/chat window, and all of a sudden, it would be like I hit my mouse and navigated away so I couldn't type. I've restarted the computer, and that seemed to help as it's no longer doing that.

I've accidentally dropped my laptop several times, but they weren't bad drops and I hadn't noticed any issues until now, and it's been awhile since the drops, so I'm confused. Hopefully some compressed air will clear up any further issues.
