B580 not detected after bios update

[Hypn0s]

Due to my system getting stuck on restart, I updated the bios of my B550 Aorus Elite AX V2 to the latest version (FGg).

This fixed the issue, but my system will no longer recognise my Sparkle Intel Arc B580. It will not show up in device manager, even after updating the intel graphics drivers to the latest version (101.6881).

Here are the solutions I have tried so far, to no avail:

- Ensuring Resizable BAR and Above 4G encoding are enabled

- Disabling SVM

- Uninstalling all graphics drivers with DDU in Safe Mode, then reinstalling latest versions

Please find attached the SSU report for more system info.

i would recommend 2 things, remove the device from the system and run "device cleanup" (run as admin, remove all ghost devices) and 2, re-flash the boards latest bios using the re-flash feature of the board if applicable, sometimes the update process only partially works, also make sure it dosnt default to CSM mode, as this can cause arc cards to fail to function on some boards even as a basic display adapter.... (just the exp of myself and several friends who all own arc cards) 

i have had nvidia and amd cards do this after a bios update in the past, once i had to use safemode, device cleanup, run chkdsk /f, sfc /scannow and the dism restore command to get the gpu to show back up... and i had to do this on more than a dozen systems... that got updated via ms update rather than the typical user applied or update app applied bios updates... i later found out why.. security flaw in the first 3 bios revs for those systems that made it possible to brick the system remotely... requiring a clamp flash to the bios chip to get it bootable again... anyway that was a PITA.. 

hope this helps..

oh also.. you can try a dif slot if your board has more than one... sometimes that can help.

Hi,

Thanks for your reply. The card is now being detected again and works perfectly.

I have no idea why it wasn't working before and no idea why restarting the pc 10+ times fixed it, but it did.

I'll keep your advice in mind for the future though, thank you.
