Thanks for the reply. Its pretty hard to see the pins due to the CPU heatsink and the massive size of the card. Initially i thought it could be a pin connection issue so i removed the motherboard chipset heatsinks incase they were stopping the card from fully slotting in. I guess I should remove the motherboard from the case & remove the CPU to get a good look at whats going on. I also just ordered a MSI x570 motherboard out of frustration so that will tell me one way or another if the Card is more likely to be at fault.
While searching online I did find a few instances of people with similar issues with different cards but there was mixture of reasons. Faulty motherboards, faulty video cards, BIOS issues and even poorly seated CPU's or CPU's with bent pins (the one thing i haven't checked yet)

If it was some issue with bent pins on a cpu, you would expect to see issues regardless of video card installed.

EDIT: IF you can get the ard into windows, check your system voltage, power draw, power from the pcie slot, power pin voltage and wattage etc. Just see if you see anything off. GPUZ can give you all this info. Open the software and go to sensors tab. If you can run a 3d load try it and see what you see. If its a problem with seating you will likely see some odd behavior on the power draw and clocks. Power draw would be unusually low under load for example, but clocks and voltage may be super high. Ive seen the symptoms so I just kinda know what it looks like now. IF however you do verify the card is slotted 100% then Im truly at a loss. The fact that you have issues even in bios screen to me is really telling. It is not any kind of software issue. Its 100% hardware or bios level issue.

I managed to run GPUZ for a couple of minutes or so in slot 1 before the machine was unusable. GPUz wasn't able to record data every second towards the end of the file as the machine was locking up a lot. I also ran it when the GPU was in Slot 2 and recorded some data. I attached the results in a image.
The only real differences i saw was the GPU clock increased to 2010mhz while the memory clock stayed at 101.3 & also the PerfCap Reason changed to a value of 4 "Indicating perf is limited by reliability voltage." This value was always 16 on slot 2. I also noticed the 3090 fans came on a lot more when it was plugged into slot 1 like the card was under more load though the stats didn't really show that.

I swapped out the Motherboard for the MSI x570 Tomahawk and the 3090 is now working fine in slot 1 at PCI4 x16. Interestingly the 3dmark score for the PCIE 4.0 x16 slot is about the same as it was for the 4.0 x8 slot on the Asus MB. I guess the 3090 doesn't need a x16 slot to get the most out of it. Just curious as to what the Timespy graphics score is in your system? Mine is around 20100 with the default GPU clocks.
After removing the Asus MB and the CPU i also slotted the 3090 into the MB to see if it was seated level. From what i could see everything looked ok.
One scary thing that happened was when i removed the Heatsink it was stuck to the CPU (i used some fancy paste/glue). When i yanked on the Heatsink a little harder the CPU was ripped out of the CPU Slot (still attached to the Heatsink) while the CPU lever was still down. I thought maybe i had destroyed the CPU but luckily I hadn't.
