SecureBoot Error [520]

[Denke]

Since severall weeks stops my HP desktop on each cold start with one beep and the message:

"HP Sure Start detected an unauthorized intrusion to the HP runtime system firmware executing out of main memory.

This could be an indication of an attempted attyck on runtime firmware executing from main memory ...

... For more information please visit http://www.hp.com/go/techcenter/startup [520]"

 On techcenter (on the web) I see the same remarks and the suggestion to ask HP support ...

The lock can be delocked by click the ENTER-KEY ones. Then the normal boot will going on.

But this is boring and make me tied about the diagnosted "attacks" on runtime firmware.

To your information: All updates and drivers are up to date on the last status, also firmware, bios, drivers.

My problem is to find out what the reason is for that boot intervention and stop.

My garanty for the HP-Desktop is still activ, but here in Switzerland is the personal support only by phone and nobody is there to answer hour by hour and day by day.

For any help I thank you so much in advance from Switzerland.

THINK !

I have the same problem since my BIOS update on my HP Z2 Tower G5. A rollback of the bios didn't help.
