Graphics Card Not Detected after BIOS Update

Hello,

I am new here and I have a problem: I had to do a BIOS Update because TPM Enable wasn't recognised by Windows 10. After having flashed BIOS-Version P4.40 the TPM recognition worked fine. However my Graphics Card is no longer recognised.

Configuration:
Motherboard: Z390 Phantom Gaming ITX/AC
Processor: Intel Core i7-9700 3.00GHz
RAM: 32 GB
GPU: Nvidia Geforce GT 1030


Steps I have undertaken:
- Cleared CMOS
- Put Graphics Card into PCI Slot 1. -> Unsuccesful
- Put Graphics Card back into Slot 2. -> still not recognised.
- Set the PCIE1 link speed to "GEN3"
- Tried both outputs on my graphics Card with 3 different monitors (just to make sure)

What else can I try? The graphics card worked fine right until the upgrade. At the reboot after the update I got a black screen and had to plug my Monitor into the internal GPU.

Thanks for reading and trying to help.

Thank you very much for your help. I tried the complete CMOS/RTC clear as suggested by your post. Unfortunately, it didn't help (though the CMOS was indeed cleared and every setting went back to default).

After praying to Jesus for a solution, all of a sudden I remembered having read somewhere on the Internet about Riser Card Support. So I turned it on and set it to 8x | 8x. That did the trick. Everything is working now. (I don't know what a Riser Card is but in hindsight I guess that it is the extra kind of "Breakout Card" that my GPU is plugged into).

Your help made me try again - so it wasn't in vain. Thanks for responding so promptly.
Yours
Uli
