I can't see why a Sapphire is any different to any other ATI card. I've used various models of ATI cards over the years, including Sapphire, and have never known the official drivers not to work. You should be able to install the official ATI driver and Catalyst Control Center, or the unofficial Omega driver (aimed at gamers who want higher framerates and image quality).

Please post a link to the site where you downloaded the Sapphire driver so we can compare it to the ATI driver.

What error do you get when you try to install the official ATI driver? If you're installing the whole package (driver and CCC), you need to have Microsoft .NET Framework installed first.

Did you follow the correct procedure for updating graphics drivers? Uninstall the driver, reboot to VGA mode, disable antivirus, install new driver, reboot to complete.

For general use, 3GB virtual memory is about right. Any more than this would be wasted hard drive space. Make sure the Initial and Maximum settings are both the same for the swap file. This creates a static file rather than a dynamic one which is constantly changing size.

Any chance you could upgrade the RAM to 1GB or more? This would make your computer feel alot more responsive.

Also, your OS is listed as XP SP2. Service Pack 3 has been available for a while now, and is recommended.
