Which BIOS version is your MB on?
You need to contact your VGA manufacturer & they will provide you with a new BIOS to flash your video card.
NB:
PLS note that flashing the video card is not that easy & requires some skills. If you have the know how go for it. If not pls provide some more information as to which BIOS is on your mobo & the exact model of your card. Then someone will walk you through it.
