Hellen,

thanks for your help,but drivers downloaded from the link which you sent could not solve the issue.still after every restart of machine drivers does not appear in network & shearing centre.Yellow mark in device manager--network adapters.Then every time I have to uninstall it & reinstall them using plug & play option in device manager .

Somehow, the PnP indication is being wiped out. There is something going wrong in the BIOS. I suggest that you do the following:

1. Power down the system, unplug from wall and remove the CR2032 battery for 15 minutes. On power up, to into BIOS Setup, set the date and time and then exit BIOS Setup with a save.
2. Reinstall the latest BIOS - but this time using the Recovery Method (see here: http://www.intel.com/content/www/us/en/support/boards-and-kits/000005630.html?wapkw=bios+recovery Recovery BIOS Update Instructions for Intel Desktop Boards and (if necessary) here: http://www.intel.com/content/www/us/en/support/boards-and-kits/desktop-boards/000005859.html Updating the BIOS to Support 3rd Generation Intel Core Processors).
3. Go into BIOS Setup and then use F9 to set the BIOS Configuration to defaults. Then, make any changes to the BIOS configuration that are necessary for your hardware configuration (boot order, etc.) and then exit BIOS Setup with a save.

Hope this helps,

Dear Scot,

As per your suggestion removed BIOS jumper for recovery option using USB,but then after booting machine display is gone so could not complete the process.So reinstalled the jumper & Battery Again & booted machine normally in Windows 7.So our problem remains continued as it is.

Well, we've exhausted the possibilities. If the board was purchased less than three years ago, you can have it replaced by Intel (contact Intel Customer Support). If its too old, disable the onboard LAN in BIOS and insert an add-in LAN card...

Sorry I didn't have a better answer...

Dear Scott,

Thanks for your help,I will check about warranty or else use additional PCI LAN CARD.

Thanks once again
