My work today gave me a Quadro FX 3400 PCI-E that was de-integrated from a customers server who ordered an upgrade. Well I was reallly excited since I just upgraded my system over the weekend and actually needed a PCI-E card. Well when I got home hooked it up and hooked up a 4pin molex to 6pin PCI-E adapter and the system wouldnt boot at all, I thought it might have been my power supply with 350watts but I tried it in a friends with a 500watt PS with the same issue. The motherboard has its LED for power but nothing will turn on. The card did come from an IBM system so I'm thinking it might be proprietary but not sure. Any insight would be greatly appreciated.
