iMac (Early 2008), OSX 10.8.2 randomly crashes, displaying only a white screen. Is there any indication what this could be or how to approach the problem? Also, where can we find the Apple Hardware Test (AHT) for the iMac?

iMac, Mac OS X (10.5.2)

    The AHT is on the DVD that originally came w/your computer.

    The next time you have the problem, note the exact time: hour, minute, second.

     

    If you have more than one user account, these instructions must be carried out as an administrator.

     

    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.

     

    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.

     

    Scroll back in the log to the time you noted above. Select any messages timestamped from then until the end of the episode. Copy them (command-C) to the Clipboard. Paste (command-V) into a reply to this 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.
