It's a good idea to blast out your electronics with compressed air once in awhile. You should be able to buy compressed air from any department store with computers. It's easy maintenance that gets overlooked by many.
Yeah, my friend told me about that recently. I'm going to get a bottle if that once my uncle fixes it.
Well I'll be a monkey's uncle! Just kidding, then I'd have to fix your computer.
You can still be a monkey though. :3
