SOS! Windows could not detect a properly installed network adapter

Sub Styler said:

Go to support.asus.com, download the manual for your board, check if there's a jumper to enable/disable on-board LAN. If there is, open up and confirm it is still in place, they are usually a firm fit these days and don't tend to fall out accidentally like early cheap mobos might have.

Get the asus site driver, double check the BIOS to ensure everything required is enabled and IRQs are Auto etc.

Other than that I'm going to bed. Hope you sort it or I will be back tomorrow.

I have already read the manual which I got with the board. I took a quick look and there is no jumper for this case. It only shows the LAN in motherboard and where you should put the ethernet cable.

The LAN has two lights on it. One left one right. The left one is for the active connection (if it's green) and the right one is for the size of the connection. In mine it's only the right one there, that means that connection is not active. That's all about LAN.

Do you think that format would solve the problem?

Thanks for replying, hope to find out the solution soon, almost 7 hours looking for it, my head looks like a volcano.

Can you test the Network Card in any of the other PCs?
If it doesn't work in any PC, you can be pretty sure the card is bad.

The second network card is not working. I tried it in another PC as well.
Thanks for reply

Hello everyone,

I tried the following I read around:
- Unplug everything from PC and wait around 10 minutes, then plug them back.
- Safe mod uninstalling drivers and reinstalling them. Same error.
- Bring back my RAM and run. Same error.
- Restore default BIOS settings. Same error.
- Add a network card (not sure that it's working, it's an old one). Same error.

My OP: Windows 7 Ultimate x64
My motherboard: ASUS P5Q-EM

Hello,
I already answered to this question on my first post.

Thanks for the reply

Sorry, missed that.

Try a ClearCMOS procedure:
(consult your manual for the exact procedure on your motherboard.)
But in general it goes like this (CLRTC and ClearCMOS are the same thing):

• Note all your current BIOS settings
• Shut down the computer > remove the power cord.
• Remove the 3v motherboard battery.
• Move the CLRTC jumper from pins 1-2 to 2-3.
• Touch a metal part of the case and Press and Hold the reset button for approx. 30 seconds to discharge all power from the board.
• Put the CLRTC jumper back on pins 1-2.
• Replace the 3v battery > replace the power cord > boot.
• Immediately go back into BIOS. If the CLRTC worked you will need to reset the date and time. Go to the Exit menu and "Restore BIOS Defaults", Save & Exit to reboot.
• Immediately go back into BIOS and now reset all your preferred settings.

See if that brings the adapter back.

Hello,

Just cleared CMOS. I made everything right according to your guide and my board's manual. The BIOS asked for a new date so I guess I've done it correctly.
Unfortunately the network adapter is still not working. Nothing changed.

Thanks

OK, so I will try to uninstall and reinstall all the motherboard drivers again.
If this fails, I will make a format on my hard disk.
If nothing happens I will buy a new network adapter and see the results.

What do you think?

Thanks
