I have a HP Pavillion Model No. p7-1423w I replaced the stock power supply with a 600B 600W Bronze Power Supply.

And installed a EVGA Geforce GTX 660 and have it powered by the new power supply.
When I connect the new graphics card Via DVI-D And I got no signal.

I rebooted into the BIOS to try to disable the on board graphics but I saw no option to do so.

Any help would be appreciated Im nervous about this $320 investment if it doesn't work. Any ideas on what could help?

Did you plug in the 6/8 pin power connectors to the card itself?

While there may not be an option to disable the onboard, there likely is an option to set which one gets initialized first. Look for a IGP,PCIe,PCI option and set it to PCIe or set so PCIe is first.

I did figure out how to disable the onboard, however it did not solve the problem, And there is no option for that in the bios at all :[

Did you install the driver for the nvidia GPU? Do you have the DVI cables plugged into GPU DVI ports?

Drivers - Download NVIDIA Drivers
No i havent installed the drivers, I thought i needed to do that after the card is already in my PC? and yes the DVI cables are plugged into the GPU
Once you you've turned off the PC, unplugged the power cord, taken side panel off, install GPU into PCIe x16 slot - should be the first PCIe slot closet to CPU, then plug in power cord, turn on PC, after completely booted up, then immediately download the GPU software/driver.

I get to signal to monitor when I have the GPU in.. All the plugs are in correctly and everything I think it has something to do with Windows 8.. :/
