Do these steps:
A few swift kicks to your computer
Lift it up several inches off the desk or floor, and let it drop. Do this twice.
Pick up your keyboard, and slam it down. Repeat. And do it hard enough to where at least a couple of the keys pop out of their pins.
If your mouse is cordless, pick it up and do some practice throws with it into the wall. If it has a cord, whip it around by the cord and then throw it like a lasso.
Punch your monitor a couple of times. Nice hard jabs.
When you are done, your computer will still not work right. It might even work worse. But you will feel great!
