    Open console in Applications>Utilities, check the system log for the date/time of the last problem  & the Startup right after that for clues.

     

    Click on the top line we want, Shift plus click on the bottom line we want, CMD+c to copy, then paste the text in a reply with CMD+v

     

    A few dozen lines should be about right, hundreds or thousands won't likely be readable
