My computer keeps crashing, I don't know much about computers though so I don't know what to do. Can you please help me?
I'm sorry to hear that! I'd be happy to help. First I will need some information about your computer so that I can best help you.

1. What type of computer are you using? Mac, PC, Linux?
2. How old is your computer?
3. Is anything in particular happening right before the computer is crashing? For instance are you starting up a resource-intensive game, opening a browser, or something else that is repeatable?

Answering these questions with give me a better idea of the actions I can suggest to help you prevent your computer from suffering more crashes.
