    Replacing Onboard Graphics

    Hi Guys,

    i'm attempting to replace the faulty Geforce 6100 O/B VGA with an ATI X1950 pro,i realise i have to disable the onboard vga in the bios the problem is there isn't,as far as i can see a facility to do so only a facility to alter where the pc looks for a video signal from first,does anybody know how to disable the o/b vga,my Mobo is a ASUS A8N VM,would a 550W PSU be enough to run this card? it gives 18a on 12V1 and 17a on 12v2,i've taken the card out and as far as i can see it's not damaged all i get when i turn the system on( the card is powered and the fan operates) is DVI signal not present,the DVi cable is new,when i unplug the DVI and switch to VGA i get an image,albeit a very poor one, on the monitor,do you think the card is kaput and should i return it for a replacement?Any help would be appreciated.

    Cheers

    Andy

    If there's not an option in the BIOS, then there's probably a jumper on the mobo itself you need to move. Have a look in the mobo manual. In terms of power output, what make is the PSU?

    Re: Replacing Onboard Graphics

    Hi,
    I've downloaded a copy of the MOBO manual from Asus i'll have a flick through it to see if it sheds any light on the matter,the PSU model number is HEC 550-TD-PTE it's not a brand i've heard of the rig is a Mesh Matrix Athlon XP3800 dual core.

    Cheers

    You don't have to disable onboard graphics. As soon as the dedicated graphics card is detected, the onboard graphics are disabled, on 95% of boards anyway. Looks like your problem is elsewhere, probably that random PSU.

    If you haven't already then uninstall any previous graphics card drivers and install the latest ati ones. Pick the driver for your OS here.

    If the on-board is enabled/working won't it just prompt you to reinstall the drivers on next reboot.

    They disable themselves when a dedicated card has been installed.

    Re: Replacing Onboard Graphics

    Does your PSU have a 6 pin PCI-E power connector? if it doesn't then what does your molex to PCI-E adaptor cable look like and are all the pins on the 6 pin all connected. The reason I ask is that I recently got an x1950 pro and I hard wired my card thinking that only 1 ground connection would be fine but it turned out that the card I had needed all 3 ground connections connected before the card would boot.
