Well, I just played for about 15 minutes without a problem, and then it happened at 2:59. I closed the game, and went to the Event Viewer and didn't see anything. However, there is the occasional WMI error (if that means anything to you in this case) that says:
Event filter with query "SELECT * FROM __InstanceModificationEvent WITHIN 60 WHERE TargetInstance ISA "Win32_Processor" AND TargetInstance.LoadPercentage > 99" could not be reactivated in namespace "//./root/CIMV2" because of error 0x80041003. Events cannot be delivered through this filter until the problem is corrected.
Other than that, I don't see anything.
