STOP 0x000000C4: DRIVER_VERIFIER_DETECTED_VIOLATION
Usual causes: Device driver - see parameters for more information
Your latest dump file lists
KeyAgent.sys as the probable cause.
This is an Apple driver, which is about all I can tell you about it!!
Old and incompatible drivers can and do cause issues with Windows 7, often giving false error codes.
Random stop codes can often indicate hardware issues.
As a Priority:
KeyAgent.sys Sat Dec 12 09:37:21 2009 Check for updates. In fact check for any Apple based driver updates, they're all quite old.
Link Removed - Invalid URL
Drivers that pre-date Windows 7. Update:
giveio.sys Thu Apr 04 03:33:25 1996 This is an old driver that was used by Speedfan. Initially rename it to say, giveio.bak. This will break it and anything associated with it. If all is OK after a few days then you can delete it.
Drivers with Updates:
RTKVHDA.sys Fri Sep 11 14:44:25 2009 Link Removed
