I have a compaq Presario that came with windows 98SE.Recently I Upgraded it to Windows XP Pro SP2.Since then My ESS Integrated Audio Card can't load.I keep getting the message ESS PCI audio controller can't be found. I then downgraded it back to Windows 98 SE thinking that would solve the problem but it did not.So this is my dilema right now.My computer can't locate the card.Any Idea what might have had caused that problem?

Hi your computer is not seing the driver of your sound card, you may need to download updated driver for it, you can search for the drivers of your sound card online, you can also find that on the computer manufacturers website.

to see the status of your devices go to device manager for more info.

right click on my computer icon>properties>hardware tab>device manager.

you can also uninstall, reinstall, and update device drivers here.

hope this helps.
