Question EVGA RTX 3080 not displaying/detected

[AndrewFerreira88]

Old GPU: EVGA GeForce GTX 1080

New GPU : EVGA GeForce RTX 3080 FTW3 Ultra Gaming, 10G-P5-3897-KL, 10GB GDDR6X

ASUS TUF Gaming Z590-Plus, LGA 1200 (Intel11th/10th Gen) ATX Gaming Motherboard (PCIe 4.0, 3xM.2/NVMe SSD, 14+2 Power Stages,USB 3.2 Front Panel Type-C, 2.5Gb LAN, Thunderbolt 4, Aura RGB Lighting)

Intel Core i7-11700K Desktop Processor 8 Cores up to 5.0 GHz Unlocked LGA1200 (Intel 500 Series & Select 400 Series Chipset) 125W

Corsair RMX Series, RM850x, 850 Watt, 80+ Gold Certified, Fully Modular Power Supply (CP-9020180-NA)

I have the graphics card installed to the motherboard and connected to the power supply. The lights are on, but the fans aren't, probably because it's not being put to use. I'm using HDMI and my monitor is showing no signal, but it works when I plug it into the integrated graphics.

I used DDU to uninstall my previous drivers and now I can't install the new drivers because NVIDIA says "No NVIDIA GPU is detected on your system. This graphics driver could not find compatible graphics hardware". Looking at my Device Manager, the 3080 is not in Display Adapters, but under "Other Devices" there are 3 PCI Devices, SM Bus Controller, and an Unknown Device .

I have updated my BIOS to a 2022 version, but it didn't fix anything. My old graphics card still works, so is the 3080 not compatible with my system? I'm not sure what to do, can somebody help me?

I have the same motherboard running Gigabyte 3080Ti no issues there. Either the card isn't being fully seated or it is faulty or became faulty during shipping. Hopefully the former as that's less mucking around, check length of card isn't touching something preventing it seating correctly.

I have a NZXT H710i case by the way and the 3080 fits well inside. I've seated it in several times and have swapped it out for my 1080 which works perfectly at the moment. Is there anything else I can do or should I just consider it faulty and request an RMA?

There's nothing special required to run 30 series, it's drop in and off you go. I'd rma.
