Q: My computer's weird.

I'm using Macbook Air. The memory is 120GB and when I check the storage, the computer said that there's an app which took up to 136GB. Which is impossible as I do not have any special app other than the basic apple app. I do not know what to do.... And there is also frequent plug-in failure. I am wondering if the plug-in failure is related to this 136GB app. Please help me out... Thanks a lot

MacBook Air, OS X Mavericks (10.9.3)

    Try these steps:

     

    - Shut down your Mac

    - Wait until your computer turns off and after that press the Power button

    - Right after you hear the startup tone, press and hold the Shift key

    - Release the Shift key when you see a grey Apple sign and the progress bar below this sign

    - Once you see Desktop, start a Disk Utility scan to detect and repair file system errors (don't forget to choose your main hard drive)

    - Click on Verify Disc and then, if asked to fix problems, on Repair Disk

    - After this, click on Verify Disk Permissions and then on Repair Disk Permissions

    - After the process is finished, shut down your Mac and turn it back on after about 30 seconds
