5830 no video, but is recognized by pc?

[Jack1Rip1BurnIt]

I have an XFX 5830 non reference edition that does not output video. The only way I can get a computer to start with it installed is to use onboard video. Once the computer is up and running I can use various programs like Trixx and Afterburner to check and see if the card is recognized, I can even play with the fan which is working perfectly. I tried checking the bios to see if anything was wrong  because there was at least one previous ower, but it does have stock bios. Anytime I try and mine bitcoins with it the pc crashes. In gpuz I noticed in the "VDDC" voltage section is showing no voltage whatsoever. Also, when I click "start mining" on guiminer there is a brief spike in gpu activity just before the bsod. Anyone know if this card is fixable?
