Random Freezing and Blue Screen

I have a 15'' Macbook Pro with a quad core i7 processor.


For months and months now my computer keeps on freezing, randomly (not related to having any particular program open) to a blank blue screen that does not go away. The only way for me to un-freeze it is close the computer and re-start it or sometimes I have to hold down the power button and shut off the computer. I've taken it to the apple store probably 5 times for this issue and because they are unable to replicate the issue in the store, they don't know what the issue is. I had apple hardware test done, a 24-hour diagnostic, and my operating system completely re-installed done but my computer keeps on freezing blue. Does anyone know why this is?

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. If you don't see that menu, select

View Show Log List

from the menu bar.

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 to the Clipboard (command-C). Paste into a reply to this message (command-V).


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.

Hello, my computer just started doing the same exact thing today! It has already happened 6 times in the last 6 hours or so. Only way to get my computer back up and running is to hold down the power button for 5 seconds. It happens with different programs opened, so I can not pinpoint it to one particular program.


Linc Davis, I searched the Console like you mentioned, and here is what I see around the last time it happened.


Does this mean anything?

But I also noticed this, and it seems shady??
