How do you fix a crashed computer?

This depends entirely on what needs to be fixed. Computers are incredibly complex and when things go wrong it may not be clear what the problem may be. If you have a problem with your computer, the best way to get a solution is to accurately describe your problem to a professional or even someone who is well-acquainted with the workings of computers.

When i go to fix a computer i bring my hands with me (it helps).
