  • Hi,

    Since this issue happened after upgraded to Windows 8.1, so first I would suggest you view the PC model in the manufacture website, and check whether the PC fully supports Windows 8.1.

    Then please make sure that the system is fully packed with latest Windows updates and latest drivers to get a better and stable performance.

    Meanwhile, please run a virus scan to ensure the safety, some malware\virus can disguise itself as system.exe, which might cause system crash.
