Are you over clocking your CPU ?
* Check the CPU specifications, and system BIOS settings

Is your CPU overheating ?
* Set the temperature alarms in the BIOS to detect over heating conditions

Newer architecture CPUs have self monitoring capabilities to allow them to detect
execution inconsistencies.

Should an inconsistency be detected a (M)achine (C)heck (E)xception event occurs, resulting in a report and a system halt.

Try using the kernel parameter


If the CPU is being over clocked and/or overheating then the problem is serious, either use the CPU at its physical rating, over clock it to a lower degree, and/or inspect the physical CPU and heatsink assembly to see if the physical contact between the two is inefficient and causing the problem.

Hope that helps
