i have a internal video card that came with my computer when i bought it, an integrated intel express chipset g33/g31 pci express video card but it sucks....bad, so i got a new one, along with a power supply, but when i booted up it went total black screen, nothing worked. its in the right slot and plugged in right i know that, but i cant even install my drivers to make it work cuz when its not plugged in it works just fine, but cant find the new card. i have a coolermaster gt 750w and a gtx 450 video card. how can i fix this? what P# goes into the video card to make it work? it works just fine without it plugged in...

did you plug in the extra power cables to the card?
Check the PCI power cable. Then check to see if the card will work in another computer.
i cant try in another computer, its the only computer i can use it in and i did plug in the extra cables.
