Notes: I am not an tech person, and cant afford to go to the geek squard at best buy, i'd like any help to solve them problem.|||There isn't one. Your using the onboard graphics probably at the moment which is why your not seeing a card. It's likely the PSU isn't powerful enough to handle the card and your other components as the card alone will take 242 watt to run at peak.



Are you getting beeps or anything on the monitor when you plug the card in and plug the monitor cable into the card? If your getting nothing from the computer then likely the PSU is not strong enough or you haven't plugged the card in correctly|||The existing graphics device in the HP Pavilion a6619f is the Intel GMA 3100. The GMA 3100 isn't an actual "card", it's an integrated graphics device that's part of the motherboard. It can't be removed, but it can be disabled, although according to that systems specs the integrated graphics isn't available when a graphics "card" is installed.

Make sure that your monitor is connected to the output port on the card and not the I/O panel on the rear of your system.



If you're still not getting anything from the card, you may need to disable the integrated graphics. To do this, you'll need to power down, remove the card and connect your monitor to the video port on your systems I/O panel (the way it was before). Power up, open Control Panel, go into Device Manager, click on the + next to Display Adapters, right click on the GMA 3100 and select Disable (DO NOT SELECT Uninstall). Your display may look strange until the card is installed, don't be alarmed, this is normal. Power down, install the card and connect the monitor to it, power up, and install the drivers. Should work fine now.



Edit

According to nvidia, a 300W or greater power supply is needed for the GT 430, the 430W psu is more than adequate for that card. (see Specifications tab)
