yes you should have two different connectors for the power have you checked to see if the bios has an update out or sometimes you may have to flash it back to
the beta it varies it could just be you are trying to draw to much through the connect that you have split i just checked that out on newegg is that the evga one if so its modular and you should have plenty of 6 pins for the video card why would you use one that splits ? if its not seated right it should post beep if its not doing anything no fan/no video it should be a power issue or the card is bad because drivers don't matter in the bios it should show video that is unless the bois needs updated and or rolled back in this case i would think it need to be updated as this is a pci-e 3.0 card is the mother board a pci-e 3.0 mobo? or an older motherboard is it an oem piece or aftermarket it could be that the motherboard needs an update to see the new video card especially if the old motherboard is not pci-e 3.0 ready it should still work you just might have to update drivers card needs Minimum of a 500 Watt power supply. (Minimum recommended power supply with +12 Volt current rating of 30 Amps.) 2 x 6 Pin not 6 pin split 2 times 6 pin 30 amps 12 volts this is probably the issue its not a gtx460 it needs power!!
ps if the card is yet another nvidia pos try this card it is better
