I'm having an issue with my graphics card being detected.
This is my second build, so I am relatively new to building computers.
The computer was booted up for the first time yesterday evening, it ran smoothly and detected my graphics card. I'm running a msi rtx 3080 suprim. I have 3 pcie cables running to it.
I played a few games and started having issues staying connected so I decided to update the bios. I got the bios update from asus support website. I used winrar to extract the files and uploaded it to a USB. Followed the bios install, it updated and went to reboot and gave me a black screen. I booted in safe mode and got my bios to register on the screen. Then once I got to the home screen my resolution wasn't correct, I went to adjust it and my monitors resolution was not an option. I went into device manager and it is not detecting my graphics card.
Any help would be greatly appreciated.
