I had an hp envy h8-1414 and upgraded the power supply (750w) and GPU to gtx260, which was a left over card I had. ALL WAS WELL! Until I realized that card wasn't able to meet my needs, so I move the motherboard/processor (m3970am/ FX6120) into a new case with same ram (original), power supply (750w) and upgraded the gpu to gtx650. I forgot to plug in the power to the gpu and the motherboard yelled at me, so I realized what I did and plug it in (after turning the computer off). Now everything turns on except the gpu, any ideas?

I will try to unplug the card, and reset the bios and see if that works. The dumb thing with his board is that it has no one board video, so if the ext gpu isnt working, then I am SOL.
