How can I fix the rattling noise in my computer?

Episode 1088 (1:05:09)

Patrick from Burlington, MA

Patrick's computer fell off the desk onto the floor. Now it makes a loud sound when he boots it up. Leo says to turn it off right away. He should make sure he eliminates static electricity and then open it up the case and inspect the fans. Chances are, one of those fans was dislodged and it's getting in the way of the fan blade of the computer. That could short circuit the PC.

Patrick should make sure all the fans are spinning without hitting anything, and check that everything is seated properly. Leo says he can turn it on before closing up the case to see where the sound may be coming from. If it's still there, Patrick will see where it is so he can power down and fix again. But if it's not obvious, then Leo advises bringing it in to someone to fix.
