Trouble replacing my onboard graphics card

[Kurlkurry]

Hello all, I'm new around here so please forgive me if this is not the right place for this.

I recently bought a new graphics card, an Nvidia Galaxy GT 440, to replace the onboard Geforce 9100 that came with my computer, and are having trouble getting it up and running. Card is installed and seated correctly (triple checked) but whenever I attempt to boot up my comp I have no display on my monitor. I went into BIOS and selected the PCI-E as my primary video but still no success. My setup is an HP Pavillion p6320y (specs: http://h20000.www2.hp.com/bizsupport/TechSupport/Document.jsp?objectID=c01969880&lang=en&cc=us&contentType=SupportFAQ&prodSeriesId=4079858&prodTypeId=12454). As near as I can tell, the power supply should be enough for the card. I have not gone through the device manager and disabled the onboard card, for fear that if it doesnt work I will be completely out of luck with no display at all (it currently works if I simply plug the VGA cable back into the standard port). Any feedback/info you guys could provide would be great, and thanks in advance.

The HDMI/DVI/VGA cable must be connected to your new graphics card. not the one on the motherboard(where all the USB ports in the back are).

Timarp000: That is when my TV/monitor gives me the blank "No Input" screen. The only way I can get a picture is when I plug it back into the standard port.
