2011 iMac Blue Screen

My iMac is sometimes, seemingly randomly, sitting on a blue screen when I walk in and try and wake it in the morning. I reboot the iMac every night.

The iMac has an external monitor.

I can't access the iMac from ARD when it's in this state; it shows it as "ARD not active", so it looks to be frozen.

Someone posted this, yet I would rather not lug the iMac into the Genius Bar if there's some other rational explanation...

This is what the screen looks like:

Here are the specs:

Model Name:	iMac
Model Identifier:	iMac12,2
Processor Name:	Intel Core i5
Processor Speed:	3.1 GHz
Number of Processors:	1
Total Number of Cores:	4
L2 Cache (per Core):	256 KB
L3 Cache:	6 MB
Memory:	12 GB
Boot ROM Version:	IM121.0047.B1F
SMC Version (system):	1.72f5

Thanks for any assistance.

iMac, Mac OS X (10.7.4)

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.

☞ If you’re running Mac OS X 10.7 or later, open LaunchPad. Click Utilities, then Console in the page that opens.

Step 1

Enter the word "windowserver" in the Filter text field. Post the messages from the time of the last crash, if any — the text, please, not a screenshot. Do the same with the word "loginwindow".

Important: Some private information, such as your name, may appear in the log. Edit it out by search-and-replace in a text editor before posting.

Step 2

Still in the Console window, look under System Diagnostic Reports for crash reports related to WindowServer or loginwindow. The report name starts with the name of the crashed process, and ends with ".crash". Select the most recent report and post the contents — again, the text, not a screenshot. In the interest of privacy, I suggest that, before posting, you edit out the “Anonymous UUID,” a long string of letters, numbers, and dashes in the header of the report, if it’s present (it may not be.) Pleasedon’t post shutdownStall or hang logs — they're very long and not helpful.

Nothing for WindowServer or loginwindow under System Diagnostic Reports, yet I found these at the time of the crash:
