This appears to be a typical software driver bug and is not likely to be caused by a hardware problem. This problem might also be caused because of overheating (thermal issue).
A third party driver was identified as the probable root cause of this system error. It is suggested you look for an update for the following driver: cmdguard.sys (COMODO Internet Security Sandbox Driver, COMODO).
