Windows 7: Onboard LAN wont show in Device Manager

Onboard LAN wont show in Device Manager


I have a Jetway PA78VM5-H-LF motherboard. - JetWay JPA78VM5-H-LF AM2+/AM2 AMD 780V HDMI Micro ATX AMD Motherboard

It's discontinued.

Downloaded the lan drivers for the onboard lan at Jetway.

Jetway - Tech.On The Move - Motherboard - PA78VM5/PA78VM5D

Went to install and I got this error.

The RealTek Network Adapter/Controller was not found.
If Deep Sleep Mode enabled Please Plug the Cable

I went to device manager and the device isn't showing up at all.

I don't have the device under network devices. Even when showing hidden devices.

Onboard Lan is enabled in bios.

Really clueless why it wont show up in device manager.

The weird thing is when I shut my computer down and restart it the ethernet on the back of the mobo turns red.

I have to unplug the tower and power cycle it to get it to restart.

And whenever I get into Windows 7 (64) the clock is always reset.

Any idea? I've pretty much done everything, I have never used it since I have a wireless USB device but I need to use the Ethernet for the time being.

I will try to install chipset drivers.

Maybe I need to update the bios? Anyone know a good how to flash guide?

Cmos battery replaced.

Would that affect the LAN?

If you have the on board LAN chip enabled in BIOS but it does not show up in Device Manager even as an unidentified device then the likelihood is high that the chip and/or motherboard is defective.

Try resetting BIOS defaults. Then try a Clear CMOS. See if that will light up the chip.

Also try connecting an Ethernet cable to the LAN plug. See if the LED comes on.

EDIT: Looking again at that error message, it mentions Deep Sleep. Is there anything in the BIOS about that? If there is, turn it off.
