Windows 8 BSOD on Windows 8.1 64 bit (system_service_exception and kernel_security_check_failure)

Thank you for a quick response. I have just ran scannow as administrator, found no problems. I am still using the old PSU as it gave 0 trouble. If some problems with starting PC come up I would buy a new one. I will reinstall WMware, update bios and run memtest in the next days and report back if there is something relevant. Thanks again.
