Unfortunatly the faulty unit you sent to us is beyond repair, and we are currently unable to replace your card for the time being.
However, we have arranged to have one of the latest as-of-yet unreleased cars to be sent out to you as soon as we receive stock of the item.
We are aware of the fact you will be without a graphics card for the time being and have arranged for you to be shipped one of our low end cards, free of charge as you mentioned your motherboard does not support onboard graphics.
We hope the above solution is satisfactory to your needs, if you have any further problems, don't hesitate to contact me
