just looked at the event log im getting this The system has rebooted without cleanly shutting down first. This error could be caused if the system stopped responding, crashed, or lost power unexpectedly.
and
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.
and
The computer has rebooted from a bugcheck. The bugcheck was: 0x0000007e (0xc0000005, 0x00000000, 0x8e513744, 0x8e513320). A dump was saved in: C:\Windows\MEMORY.DMP. Report Id: 010912-18813-02.
