Hi guys, here are my SPECS:

ASUS P5KPL-CM Mobo (onboard GB PCI-e LAN)
E7400 Intel C2D
2GB DDR2 800 RAM

Ok so what happened was, I sold my PCI-e graphics card. I SWITCHED to onboard gfx for the time being. I booted into windows. installed the driver. After I installed the driver, I noted I could no longer access the internet. I checked the Device manager and What the?!?! no networking devices whatsoever!

I have tried restarting the machine lots of times, different cables, and even putting a PCI-e Card back in...

Whats going on with it?

BTW...board was bought at the beginning of this year....should I just try to get a new one?Just a thought... Maybe the Network Interface Card (N.I.C) has failed? I have the same problem where if I try to setup a network, it just won't work with any SETTINGS. Tried replacing the cable and that didn't work. It was usable before, but not anymore.

Do you have the diagnostics for the N.I.C? If yes, run a test and see if it works.

EDIT -
If not malfunctioning, it could be turned off in the BIOS setup.I did a hardware upgrade recently, after which my on-board LAN port stopped working. I found clearing the CMOS and letting BIOS re-detect all the hardware cured the problem.

In my case, I had to move a link on the MB (located near the CMOS back-up button cell battery) to a different POSITION and leave for 60 secs with ALL mains power turned off before re-instating it to the normal position and powering up into BIOS and re-entering any customized configurations that you normally have.

Your motherboard manual should be able to advise the correct method of clearing CMOS memory in your case.I took the battery out and reset it...no luck

I sure hope it hasn't...it wont show in device manager

I'm using an old 10mb/s pci nic in the mean time...Did you install the motherboard drivers? You may have to reinstall them to get the NIC to start again.

I have run a asus board and the NIC wouldn't come up with out the MB drivers. It sounds like your having the same problem.

A brand new NIC card is 10 or 15 Bucks....
