No BIOS post error messages, no HP logo after power on

HP Recommended
Z6 G4
Microsoft Windows 10 (64-bit)

I have connect a magma PCIe expansion via PCI Express x8 host card and a USB ICRON LAN expansion. If the PCIe expansion ist connected, no BIOS post error messages will appear on display and no HP logo, nothing. And Computer doesn't boot Windows. After more than 3 sek. pushing the power button, the computer will switch off. If i disconnect the PCIe expansion, the computer boots up completely. GPU is a Nvidia P4000.


But the PCIe expansion is connected an the USB ICRON LAN expansion is disconnected, the computer boots up also sucsessfully. After i do this, i am reconnect the USB ICRON and it work also, rather than restart the computer.

My main question: Where is the "post error messages" an the "HP logo" at unsuccessfully computer restart? At this time, the computer work, but i have fear that this tomorrow is no longer the case.

Can you try that PCI-E adapter card in some other HP computer, or in some other non-HP computer?

If it does not work in those computers, replace it, or contact the manufacturer, for technical support.
