hpe-510t won't boot with new gtx 660

[hughjass5976]

I recently got a new PSU and GPU to upgrade the PC's gaming ability. PC came with a gt440, and I am upgrading to a gtx660. Power supply was upgraded to a Corsair 750M. The problem is when I go to start I get to the blue HP start screen and it just sits there. There are three beeps spread out by ~30 seconds each, and then the screen goes black with a blinking cursor icon in the corner. The PC came with windows 7 so it is not an UEFI problem. Everything works fine when the old card is put back in.

Can anyone help me with this?

Use the intergrated graphics to install the drivers first.

Trying it now

Nope, cant install as it doesnt see any supported hardware. And if the card is inserted it will try to boot from it and fail. Pc started when the pci e slot was turned off and card installed, but of course couldnt install drivers because it couldnt see the card.
