How to install a graphic card over a integrated graphic card

Guys i have a system with good 2gb ram
and a bad 1.8ghz pentium dual core processor on a motherboard which supports pci-e slot
actually the motherboard has a intel 82945g graphic card inside
i bought a ati radeon 5450 compatible with my system
i uninstalled the intel driver and when on bios the primary video adapter was aldready set to pci-e
i attached my monitor with the card
and start it but the monitor is simply black(if nothing is connected it would display a message that says to connect)
so the monitor doesnot says that there is no graphic card attached but it is simply plain black while cpu runs good
it is just balck but when i put the pin back to the old slot it shows the screen
(cpu has no problem it always boots)
so whats the problem with my graphics card and how to fix it

  1. You probably have a Radeon 5450 PCIe 2.1 version. Those aren't compatible with most very old systems because PCIe 2.1 is not compatible with PCIe 1 motherboards.

    To confirm this, you could give me spec info for your graphics card and motherboard or if you have an OEM system (a pre-built from a company such as Dell or HP), then the computer's model number.

    If this is the issue, then your best option would be to get either a PCIe 2.0 card or a PCIe 3.0 card (PCIe 3.0 fixed the bug in PCIe 2.1 and PCIe 2.0 never had it). If the issue is something else, then chances are that you got a faulty card and it should still be replaced.

    my cpu was built by HP it sthe compaq series model name SG3340IL
    it has 2GB RAM
    PENTIUM DUAL CORE 1.8gHZ processor
    the graphic card is http://www.flipkart.com/powercolor-amd-ati-radeon-hd5450-1-gb-ddr3-graphics-card/p/itmd5vrzwe6g9qry?pid=GRCD5VRZZ9URJFXD

    and i cant lose the card pls tell some way to get it worked pls
  3. Sorry, but my suspicion was correct. That is a PCIe 2.1 card and a PCIe 1 motherboard. I'm told that there is a way to flash the firmware on the PCIe 2.1 cards so that they'll work in PCIe 1 systems, but that PCIE forced downgrade needs to be flashed in a PCIe 2.0 or newer system. This also ruins your graphics card's warranty and can destroy the card if not done properly or even if you're just unlucky.

    Your best option is to replace the card with one that is compatible or maybe you can send the card back for the company you bought it from or its manufacturer to do the firmware flashing for you, if they offer that. The shipping costs for that might be worse than the cost of buying a cheap compatible graphics card anyway.
