please contact your technical support team.
•
If the computer configuration has changed, restore the
original factory settings. Remove all third-party modules,
then restart the PC. If the error no longer occurs, the
third-party module was the cause of the fault. Replace this
module with a Siemens module or contact the module
supplier.
If the PC still crashes, contact your technical support team.
