X870E Tachi Lite wont recognize AMD 7900XTX GPU

   I built a new system with AMD Ryzen 9 9950X CPU, 96GB of DDR5 RAM, ASRock X870e Tachi Lite MB, AMD 7900XTX GPU, PC Cooler 1000W PSU... etc

System boots up fine (using now) GPU has "XFX" lights on but no fan movement, and most importantly no display output from any of the 4 ports. I KNOW this GPU works fine as I used it for 1 year in my prev setup with no issue. The on board HDMI port works which is the only way I can use this setup now. I have tried 3 times to remove and re-install GPU to ensure PCI slot is fully connected and each of the 3 pci-e cables are connected properly to the pci port on PSU. Reset CMOS, have latest 3.17 Beta BIOS, etc, nothing works. Any ideas? Could it be a bad MB or PCI slot?

Unfortunately I dont have another GPU to test right now.

	As your onboard HDMI comes up, you may look into Windows device manager and event viewer, maybe there's some hint ?
