    I would prefer not to format the system.

    Please suggest me what to do.

    Thanks & Regards

    dont format because it must be a hardware fault, when you ran dxdiag did it find hardware installed?

    audio is sound, if you only have bluetooth, then your sound chip is faulty as it should show, and you will need to replace the motherboard as its onboard sound

I hav downloaded intel dg31pr audio driver for windows xp but while installing it appeard as "this driver version is older than the system one". please solve my problem...,,,

Well mahatab9, you have not told us if there is any audio driver installed on your computer or not. But the error message clearly stated that, you have an audio driver already installed for your motherboard model. So, if the driver is not properly working or you just want to upgrade it, you should use Intel Auto Driver Updater for best result. This will show if there is any updated version of your installed drivers are available or not. To do this, click on the following link to automatically identify and update your drivers and softwares.
Automatically Update your Driver
Now click on "Check Your System for Latest Updates" to start analyzing your computer. This will show whether your system requires an upgrade or not.
IMPORTANT: This utility is for Intel Motherboards only.
But still, if this utility doesn't show any upgrade to your audio driver, then you can manually download this driver as your motherboard INTEL DG31PR supports the Realtek HD Audio driver only for best response. If you have already installed any other audio driver than Realtek, please uninstall that and install this one. To download this, click on this following link:
Download latest Realtek HD Audio Driver
This installation will remove any previous version of Realtek and install the newest one automatically.
Hope this helps, Regards,
