    Yesterday, I turned my notebook on (HP dv6500t) and noticed my internet wasn't connecting (wired connection). So I went and looked at my network adapters and only my wireless one was listed. Then I went and looked in the device manager and noticed that my ethernet nic wasn't listed there either. I Then tested my wireless nic just to make sure it was working properly, which it is. After I tested my wireless nic I booted in to safe mode, and my ethernet nic was working fine. So I rebooted and it vanished again. I tried a system restore a few time with now luck. I also tried reinstalling the drivers for the nic.

    After all that I backed up my files and reinstalled a fresh copy of windows hoping it would fix my problem. No luck, had the same problem only this time it wouldn't even work when I booted into safe mode. At the moment I'm reinstalling windows with my recovery disc, because if I can't fix this I will have to send it in for warranty repair.

    I would like to avoid sending it in for repair, because I have been trying to sell it recently and I have someone thats pretty interested in purchasing it.

    If it works in safe mode, there's nothing wrong with your hardware. When you reinstalled, did you install all of the required drivers and system software?

    Don't sell it if it doesn't work. Just do a clean install and it should work. What is your OS?

    He's already done an install, and it didn't work. Plus, his signature lists his current OS.

    I have 4 computers but I have just one laptop in my sig.

    I would still do another clean installation, many times it works.

    He might not have the drivers disc.

    Well as I stated above I was trying to reinstall windows with my factory recovery disc when I first posted this thread. Well it turns out that I had one of those faulty recovery disc's that HP sent out awhile back. So after that install failed I reinstalled a fresh copy of windows again. I did the same thing I did the first time I installed the fresh copy. I applied all the driver and such for my computer (I have them saved on a flash drive). Well after one of the restarts when I installed a driver, windows finally recognized the nic again.

    So thanks everyone for the replies, I appreciate your help.

    OMG, I just restarted my computer and now the nic has disappeared again. The only thing I did before I restarted the computer was install some updates from windows update (pre sp1), and turn on network descovery and file sharing. I'm downloading sp1 now and I'm going to try reinstalling the driver when it finishes.

    Anymore Ideas on whats causing this.

    Updates that were installed before it happened again:

    1) Update for Windows Vista for x64-based Systems (KB937287)

    2) Update for Microsoft XML Core Services 4.0 Service Pack 2 (KB941833)
