Hi everyone, 
 
I just got my EVGA 3080 FTW3 Ultra, and after installing it. It seems that the fans stop working after booting to windows. 

I've tried updating the drivers, but it won't let me install it, because it's not recognizing the card. 
 
I've checked the BIOS and all it shows is NVIDIA VGA CONTROLLER. 

I've tried reseating to both PCIe Primary/Secondary slots and still unrecognizable. 

I've also tried a CMOS reset but nothing. 

I'm currently running a 5800x with EVGA 850+Gold PSU (circa 2016). I have 3x 8pin straight from PSU; with the 6+2 connector attaching to the card. 

I've read the forums and some say Lights above the connectors should be ON??? they only turn on for me when I unplug a connector. 

I'm just wondering if there's a way of forcing a hardware recognition for this card?
 
CPU: Ryzen 5800x
MOBO: MSI MAG X570 Tomahawk
RAM: 32Gb Corsair Vengeance PRO 3200Mhz
GPU: EVGA 3080 FTW3 Ultra
PSU: EVGA 850+Gold PSU


Thanks in advance.

    Try installing PX1 and see if it starts a firmware update and/or recognizes the card. Also try moving the BIOS switch on the card to a different position. I assume it's on "Normal" or whatever they call it by default so switch to "OC" and see what happens.

    Thank you!! 

    PX1 Kept shutting down. Windows update had a NVIDIA controller for me to update to V.30 as an optional update. That seemed to do it and then PX1 started to work!
