There is no sound in my pc. all drivers had installed.

Hi.
First option: Go to bios setting power on your PC then press F2 or DEL if you see bios setting highlight advance setting then search for audio device need enable and press F10 to save and exit.
boot to your operating system, try see device manager for sound hardware detection.if detected just install sound driver.
Second option: if you do first option not yet working sound card. I recommend you purchase USB sound card external.it's very easy to install.

hope can help you.

you can install manually or from internet or driver detective or from mother board cd if still not satisfy contact me [email protected]

Are you using the same operating system? It seems the driver is incompatible with the operating system you are using. Try downloading the latest driver from the Intel support website.

One other option is to check if your onboard audio device is enabled in the BIOS. If it is not, the device won't be detected of course.

To check, click windows start button, point to computer, click manage, then look for device manager. If you see an exclamation or "x" mark on your audio device this means that your audio driver is not properly installed.

If audio no error marked sign and says that your audio driver is ok, uninstall it then re-install the audio driver.

It appears that you have installed the wrong sound driver.

You need to download the drivers from the Compaq/HP WEB support/download page. Make sure you select your model laptop and the XP or Vista Windows version of the drivers you require.

I bet you have to uninstall the sound card from device manager first and the restart the computer. Then try to install the sound driver again. If that does not work you may have to force install the driver from the add new hardware wizard in control panel.

I am curious, do you have a dedicated graphics card installed from ATI / AMD?

Newer ones have a built-in high-def audio also.

i have sound driver install to motherboard D845G intel

First of all when you installed the sound card and turned on your pc did your operating system detect the sound card. If it did then you would need to install the software driver. In some cases the operating system will have it built it and configure it on its own. If you installed the software and it you still got no sound, Go to device manager and find the sound card. If its there, right click and update driver. If is still does not do it then right click and remove driver. Restart your computer and it should detect your card and then reinstall software. now if it still does not work or detect your card then possibility bad sound card. Hope thats helpfull to you.

Hi babupbt, just post the model No# (you can find it printed in white on the motherboard or get it from the compaq manual). Compaq list everything on white stickers through out the PC.
I'll find all the drivers you need. (What operating system are you planning to install)? XP home, XP Pro?

i got this problem once more. try to repair drivers of the sound card. maybe it isn't as complicated as it may sound. i once got a problem like this with a customer. just roll back or repair. maybe another re-installation won't fit as its already installed.
