What should I do if I get an error message?

Record the exact error message. When your PC crashes, it'll usually try to tell you why it is doing so--albeit with a string of numbers and letters that you won't understand. Write the message down in its entirety (or take a screenshot, if possible) so you can later plug it into Google or give it to your tech support agent. If your PC didn't provide an error message, go to Action Center (in the Control Panel) and see if it shows up under 'View archived messages' or 'View problems to report'.
