My usual method of fixing things - especially technological items - is to whack them a bit. Broken cell phone? Turn it off, and give it a few good whacks. Computer monitor not working consistently? Pound it a few times on the side. And sometimes, it even works.
Marcos has a different approach. Our computer has been acting up for a few days, and he spent the better part of yesterday fixing it. Whatever he did, it took a lot longer than my method would have taken, but no complaints. We're up and running again!
