The board bios is up to date.
Our best recommendation is making sure you have loaded the correct drivers for the card and remove all other drivers that are not required to avoid software conflicts at a "driver" level. Verify with the card manufacturer for latest drivers and firmware update and confirm compatibility with the board as well.
Now, if the board is working with a different graphics card installed, then we can tell it is very possible this is a compatibility issue with the HD 7950 and there is not much that can be done in these cases rather than testing a different brand or card. Thank for your understanding.
