Onboard NIC disappeared

[Ryland]

I just upgraded my video card and on reboot my onboard NIC isn't showing up in windows. Any ideas? I just tried reinstalling the drivers and it said it can't find the hardware.

 

[sgrinavi]

been there, done that.

The video card has taken over some resourse that the O/B NIC wants. I solved mine by installing a new NIC with new drivers and disableing the O/B.

Now get this:

I had borrowed the NIC, when I pulled it out to return it I enabled my O/B network hardware and it worked..

 

[Ryland]

Ok..I was wondering whether that was possible. When that happened to you did the NIC not show up at all in device manager?

 

[Ryland]

I tried disabling COM1 and the Parallel port but neither of those fixed this

 

[nerp]

I had this problem once. I powered down and unplugged the computer from the wall. Waited 5 minutes. Problem solved after that.

 

[Ryland]

Well I had tried unplugging it for about 30 seconds but that didn't fix it. It was also unplugged the entire time I was swapping video cards out. Tried booting with the network cable unplugged too.

First thing i'd do is see if the NIC is showing up in device manager and if its "flagged" for resource conflicts.

I'd reset the mobo bios and reboot with the new video card in.

And of course, be sure to have the lates bios.

 

[Ryland]

The NIC is not showing up in device manager. I googled on the newest released bios and from what I found it causes more issues than its worth forcing most people back to the bios Im currently using.

 

[MTDEW]

Wow, that is "odd".
I'd at least try clearing the cmos.

The board didnt "flex" too much when inserting the new card and maybe harm the nic?
Its a guess of course.

Heck, disable the video card in device manager / reboot and see if that NIC shows up.

Im just throwing out stuff i'd try, cuz ive never seen this happen b4.

Gonna google this myself, wonder how common of an occurance this is.

 

[MTDEW]

LOL
I googled it.
I assume thats you on the ard Forum also.

So what happens if you put old card back in and reset bios(cmos)?
Does the NIC return?
I'd do what i could to ensure the NIC isnt dead first.
Because if it is, then you'll just waste hrs for nothing.

I haven't been able to find much on it. I did just order a new PCI nic to see if I can bring the network up that way (for $23 its not bad to offload the network from the motherboard anyway). The motherboard barely flexed, if it did at all, when I installed the 260GTX. I was being VERY careful because of the lack of clearance with the drive cage.

Yeah its me on the hardforum and evga's forum too.

Im gonna see if the new NIC works and solves the issue. I just need internet access, I don't care if its onboard or not because everything else on the motherboard works fine.

 

[Ryland]

OH and swapping the cards back out would be a major job, I had to disassemble a good portion of the internals just to get the 260 in. something I don't want to do twice but I am glad I didn't order a 280 thats even longer and definitely wouldn't fit.

 

[MTDEW]

I hear ya.
As long as you get a working NIC, i wouldnt care either.

And I sure as Heck wouldnt give up my GTX 260 for an onbard NIC.

 

[Ryland]

I do have a habit of trying to fix every problem that comes along on this board (it was BSODing at random internvals and I spent a month tracking it down to Kaspersky antivirus when a friend kept telling me to wipe and start over).

who knows, the new nic may be better than the onboard one anyway. I picked up this one http://www.newegg.com/Product/...x?Item=N82E16833106121

At my work where we have 500+ machines, we get calls once or twice a month with this problem. For us, unplugging the power and ethernet cable from the machine for 15 minutes (less time may be fine) and then plugging the power back in, loading the machine, and then plugging the cable back in has fixed the problem all but once in the last 2 years (and that was when it turned out they had ripped the plug off of the card). Good luck.

 

[Ryland]

Huh...well then, I guess that will be a test to try tonight then. This is a really bizarre problem Im having. If that doesn't work then I will probably reload Optimized defaults and see if that helps.

My machine is #2 then. I let it sit for an hour and it didn't come back.

FYI I also tried the newest beta bios and that didn't work either. hopefully the new nic will.

 

[crazyhandpuppet]

Did you check to see if it somehow disabled in the BIOS?

There isn't an option to enable/disable it in my bios settings. The motherboard manual shows the option should be there but it isn't.

 

[Modelworks]

You can try manually assigning resources in the bios.
Its not done much anymore but here is a rundown of the popular irq.

[Ryland]

Unfortunately the bios doesn't have any support for assigning resources to the NIC and none of hte LAN related entries even show up anymore (not 100% positive they ever did before either though).

 

[WaitingForNehalem]

Try System Restore.

 

[Ryland]

It doesn't even show up in the bios. I bought a PCI NIC and that is working fine (Actually better than the onboard one).

Thank you guys!, thought I had a dead NIC and was pulling my hair out last night. I have a different Gigabyte mobo and I just swapped out my video card before the problem started. Going home to undo my upgrade (temporary) to confirm.
