I'm wondering how I can know for sure if my mobo is fried or if its something I did in set up. I'm running an Asus M4A78 plus and I installed everything fine and got my os up and running and was just patching and updating drivers when suddenly the network aspect of my machine went out and I've not been able to get a response since. I used a boot disc to try and see if it was a driver conflict and the network interface on the disc didn't work either. This leads me to believe that my mobo is fried, but I wanted to know if anyone knew of any other alternatives for fixing it. I'm not very interested in starting from scratch after I just finished building the whole machine.

If this is a Windows system, what does the device manager show about your NIC? Is this wireless or wired? What OS are you running?

This is a windows system running XP. I just set it up last night and was attempting to patch the system and download AVG update files when it stopped working. My onboard ethernet is not being seen by either the windows operating system or the boot disc. Reboots have not worked, and rolling back updated device drivers have not worked either.

If you check the physical NIC, any lights?

On the motherboard is there any loose connections on the physical NIC?

included flashing the system bios you might find that you onboard ethernet port is disabled in the bios now.
Either way its worth checking that it is enabled in the bios settings

Cables plugged in all the way, bad cable, modem or switch not plugged in, signal cable to modem not plugged in properly, etc.

live CD and see if you can get on the internet. If you can then your motherboard should be ok. You can also try uninstalling your nic in device manager, rebooting and let Windows reinstall it to see if that fixes the problem.
Good luck.

Thanks. I've already booted to a boot disc and before I installed windows the internet service was working fine. Since the problems began, I've booted to the disc again and the internet service on the disc no longer connects.

Thanks for the suggestion. Do you really think it could have anything to do with the PSU having just installed it yesterday and no issues with any other component?

by medowbrookgoer39

I didn't flash the bios, but it still might be a good idea to check the bios settings. However, not sure how that could change when it was working at one point in time but just randomly stopped.

Cables are plugged in all the way, and we have a router which is connected to another computer and has great internet service right now. I'm beginning to run out of alternatives to RMA'ing the mobo and starting fresh.

your router or modem? its odd that your NIC would just kick off. is your NIC still listed under device manager?

if everything looks like it should be working try cycling the power on your router/modem

First, you should verify that the Network Interface is enabled in BIOS setup.

This is as much a sanity check as anything else.

Then, you MUST open device manager and see if there are ANY yellow "?" or "!". Any device that will not start or has a bad driver could prevent your Network Adapter from working.

Even if not labeled as such, one of those uninstalled devices could be your Network Adapter.

The Network Adapter can also hide behind a "PCI Bridge Device" that is not properly installed.

When you installed updates, were any of them for device drivers? Microsoft has a nasty habit of sending out wrong device drivers as part of updates.

I would go to the Asus web page and download the full set of drivers for your motherboard. Then, starting with the chip-set drivers, install all of the correct drivers for your board.

I would all but bet that once you have the correct device drivers installed that your Network Adapter will magically show up.

Thanks for the advice. I'll probably go look for the device drivers this afternoon before I decide to ship it back and get a replacement. I just don't understand why if it is device drivers, it wouldn't be working in a boot disc either. Doesn't make much sense to me if its drivers but it would make sense if it were the actual card itself.
