Ethernet Network Controller has a yellow question mark

by red.paul84 / January 1, 2008 8:28 PM PST

Hi, I recently reinstalled Windows XP on my system. Once done, I realised I had no motherboard CD. I managed to download most of the drivers but the Ethernet Network Controller still has a big yellow question mark next to it in Device manager. Is this a problem? What do I have to do to resolve this issue? I've got a ASUSTek Motherboard, with an AMD Athlon(tm) dual core processor. Someone please help me with this....

It will be a problem if you expect to use it

It probably means the drivers for this are not installed. Do you have an add-on NIC or is it part of the motherboard? If it is part of the motherboard, some more searching is involved. If it is an add-on then find out the make and model. Then go to the manufacturer's site to get the driver.
Belarc Advisor may be able to tell you the make and model if you cannot find it.

I reinstalled all drivers on my PC. This seems to have resolved the Ethernet Network Controller problem. But there's still a yellow question mark under 'Other Devices'. The device in question is marked as 'unknown device' in the Device Manager. How can I identify this device? Please help... Thank you.

Well, if you know what devices are installed

Start looking for one that does not work. You can also have Windows try, but do not expect that it will be that easy.
While in Device Manager, right click on the unknown device. Let Windows look for the driver by clicking "Update Driver" and allow an internet search. A longer method is to look at the printout from Belarc Advisor and start going down the list of components until you find one not listed in Device Manager. Then find the driver for that and have Windows install it.
It can be fun, but it can also be confusing and irritating.
Good luck!!

What are the on board devices on your MB?
by Steven Haninger / January 4, 2008 8:39 PM PST

Can you account for all of them? These generally include sound, video, network interfaces, USB and firewire ports, HD interfaces such as SATA, etc. It's a good bet you don't have all the MB devices installed. Sometimes add in cards are dependent on MB drivers to be loaded first before they can be recognized. Windows sees something but hasn't a clue what it is. Plug and Play devices can ID themselves but first need communicate their existence. MB drivers are often necessary to do this.
