Also thanks to Moogleys for doing his research before giving his bright advice to a novice.
What advice ? I posted a link to an unlocked MSi 5850 Bios and a link to a site explaining about unlocking the cards. I gave no advice on flashing..?
The card boots and displays with no power leads connected it should be recoverable if not by the o/p then a call to Msi would be a good start.
