I cannot start My MacBook. Upon starting the computer a note in 5 languages pop up:


You need to restart your computer. Hold Down the Power Button until it turns off, then press the Power Button again.


Doing that I get the same message again. How to solve the problem?

MacBook (13-inch Mid 2007), Mac OS X (10.7.5)

    That's a kernel panic which is usually, but not always, caused by hardware, with memory the leading cause (assuming there are no external devices attached). See this Apple note on troubleshooting it.

    Restarting the MacBook with the Option (Alt)-key pressed I came to Mac OS X Utilities where I could use the options available to restore the Macintosh HD from my external MacBackup disk used for Time Machine. Before that I had checked that the RAMs didn't seem to be any problem with and also the HD on the computer seemed to be OK.


    So it seems that it was a software problem and I was able to restart the computer and it now seems to work OK.
