HI i bought a 280x vapour x a few weeks ago and have trouble fitting my asus d2 sound card intio the pci slot below it,so i tryed moving the card from the top slot down to the bottom slot with th d2 jst above it but when i rebooted i got no display,think it has something to with the top slot being the primary,is there a way round this otherwise i wont be able to use my sound card
