Specs: Windows XP, 2,000 ghz

I installed a new graphics card and it's drivers after I disabled onboard SG3 Unichrome graphics card in BIOS but the resolution is stuck at 640 X 480.

I have searched forums on the net, re-installed drivers etc but it doesn't seem to fix the problem. Also, the new graphics card isn't displayed in device manager but it's recognised in right click -> properties -> settings on the desktop.

Any ideas on how to fix this?

I assume you got an FX5200 (yuk)?

Here' what you *should* have done:

- uninstall the SG3 drivers, then shutdown

- open the case & install the FX5200

- bootup & immediately enter the BIOS & look for settings to disable the could be a simple enable/disable, but you may also have to set the "shared memory" to none. You also need to check the "Initial Display first" setting to make sure it's set to AGP? PCI? Save your settings & exit

- upon booting into Windows, the card will be auto-detected & generic drivers installed. The generic drivers will give basic/minimal functionality. At this point, pop in the driver CD & load the nVidia drivers. If you don't have a CD, go to & download the latest available for the FX5200

In order for your graphics card to be recognized correctly
- the main chipset drivers for the mboard must be installed.

If you don't know whether they are....

State the make and model of your brand name system, or if it is a generic system, the make and model of the desktop mboard.
The specific brand name system model is usually on a label on the outside of the case somewhere, or it can be determined by going to the brand name's web site.
The model of the mboard in a generic system is usually printed in obvious larger characters on the surface of the mboard, often between the card slots.

- the specific drivers for the graphics card must be installed
- BEFORE you install the specific drivers for the graphics card, the video in Windows must be set to a default VGA mode of one sort or another
- if you were using onboard video or another graphics card previously, un-install any drivers and associated programs listed in Control Panel - Add/Remove programs BEFORE you install the drivers for the graphics card - usually that sets the video in Windows to to a default VGA mode of one sort or another

"I disabled onboard SG3 Unichrome graphics card in BIOS"

The term CARD is frequently mis-used.
Onboard video - video built into the mboard - IS NOT A CARD!
A CARD is removable and plugs into a slot in the mboard inside the computer case.

In most cases, the onboard video is automatically disabled when you install a video card in an AGP or PCI-E X16 slot, and any settings in the biossetup for it are ignored by the bios and the operating system. .

You should check the setting for Primary Video or Intialize Video First or similar in the bios setup - it should be set to AGP if it's an AGP card, or to PCI-E if it's a PCI-E card, or to PCI if it's a PCI card.
