I recently picked up a Nividia Quadro 4000 from a local flea market for 5 dollars. Not exactly reliable, but it only had a few scratches and if it doesn't work I could put it on my wall. I put it in my pc hooking up only the 6 pin power connector, not the other two that I believe are for a another optional card. I turned my pc on and the card's LED lit up green and the fan spinned but the pc just turned off, no display. I then tried it again but this time it did nothing, so I took out the card and my pc booted up just fine. I then put the card back in, but not plugging in the 6 pin power connector. The pc booted up and state on, just no display and the card's LED was now red. Tell me guys, is there any hope for this card?
