Q: My macbook air keeps restarting?

My macbook air (2012) keeps restarting. I got the logic board and the battery replaced recently and I tried to update a few days again by restarting and it froze for over 2 hours. I crashed the computer and it was fine. I finished the updates tonight after my computer kept restarting randomly no matter what i was doing and hoped it was from the update but i finished updating and it restarted again about a half hour later. I saw in a post on here to enter

syslog -k Sender kernel -k Message CSeq "Previous Shutdown" | tail | open -f -a TextEdit

in terminal and this is what came up:

 

Sep 17 07:38:20 Irinas-MacBook-Air kernel[0] <Debug>: Previous Shutdown Cause: 3

--- last message repeated 9 times ---

Sep 22 00:39:19 localhost kernel[0] <Debug>: Previous Shutdown Cause: 3

Sep 22 13:49:24 Irinas-MacBook-Air kernel[0] <Debug>: Previous Shutdown Cause: 3

--- last message repeated 1 time ---

Sep 23 00:58:48 Irinas-MacBook-Air kernel[0] <Debug>: Previous Shutdown Cause: 5

 

I'm not sure what any of this means but it wasn't negative shutdown causes so im assuming its a different problem than what the person in the other post had (it was said to be hardware/power supply related because of the negative numbers)

I hope this information helps i would like to find an answer from here before going to the apple store since it's not close by to where I live.

MacBook Air, OS X Mountain Lion (10.8.5)

    If you have more than one user account, you must be logged in as an administrator to carry out these instructions.

      

    Launch the Console application in any of the following ways:

     

    ☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)

     

    ☞ In the Finder, select Go Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.

     

    ☞ Open LaunchPad. Click Utilities, then Console in the icon grid.

       

    Select the most recent panic log under the heading System Diagnostic Reports on the left. If you don't see that heading, select  

     

    View ▹ Show Log List

      

    from the menu bar. Post the entire contents of the panic report — the text, please, not a screenshot. In the interest of privacy, I suggest you edit out the “Anonymous UUID,” a long string of letters, numbers, and dashes in the header and body of the report, if it’s present (it may not be.) Please don't post shutdownStall, spin, or hang reports.

    Make sure the title of the Console window is All Messages. If it isn't, select All Messages from the SYSTEM LOG QUERIES menu on the left.

     

    Enter "BOOT_TIME" (without the quotes) in the search box. Note the timestamps of those log messages, which refer to the times when the system was booted. Now clear the search box and scroll back in the log to the last boot time after  you had the problem. Select the messages logged before the boot, while the system was unresponsive or was failing to shut down. Copy them to the Clipboard (command-C). Paste into a reply to this message (command-V). Please include the BOOT_TIME message at the end of the log extract.

    If there are runs of repeated messages, post only one example of each. Don’t post many repetitions of the same message.

    When posting a log extract, be selective. In most cases, a few dozen lines are more than enough.

    Please do not indiscriminately dump thousands of lines from the log into this discussion.

    Important: Some private information, such as your name, may appear in the log. Anonymize before posting.
