To correct or avoid error
Check your computer configuration:
Contact Technical Support if the computer configuration

corresponds with the delivery state.
If the computer configuration has changed, restore the

original factory settings. Remove all third-party modules,
then restart the computer. If the error no longer occurs, the
third-party module was the cause of the fault. Replace the
thrid-party module with a Siemens module or contact the
module supplier.
Force a "Reset Configuration" using the BIOS Setup.

Some PCI or PCI Express cards require a lot of memory and

this must be deducted from the actual SDRAM. The
"Currently used DRAM size" must always be the "Maximum
allowed DRAM size" to ensure that the inserted card
functions correctly.
If the PC still crashes, contact your technical support team.
Use a higher capacity power supply

Check with the supplier of the component
whether this can be operated without an external power

supply,
whether the settings for the component can be changed so

that only the PC power supply is used or only the external
power supply.
