  1. Hi, I bought a new desktop PC a few weeks ago, running Windows 7 and of late is has started giving STOP errors quite randomly. I've included the problem signature below. The error was stated to be associated with tcpip.sys. I've been investigating this issue for a few days now and have tried the following things:

    1. I checked my network drivers. In Device Manager, under Network Adapters, I have two items - "802.11n Wireless LAN Card" and "Realtek PCIe GBE Family Controller". I had not made any updates to these drivers that may have started the problem. Hence, the "Rollback Driver" option for both of them are greyed out, presumably because there's nothing to roll back to. I clicked on the "Update Driver" and it told me that my drivers are up to date.

    2. I read about several Microsoft hotfixes related to tcpip.sys that were recommended regarding this issue. I downloaded them and ran them, but each one said "This update is not applicable to your computer".

    3. I restored the computer using System Restore to a point before the crashes started, just to reverse anything that I don't remember doing. After restoring, the crashes are still happening.

    4. I suspected the issue may be Firefox related, which I had been running. So I stopped using Firefox and installed Opera, but then the PC still blue screened with the same error when using Opera.


    I tried to attach the latest Minidump file to this post, but the upload limit for the forum is 200kb so I couldn't do it.

    Could you please advice on how this issue can be resolved? Thank you.

    tcpip.sys is an MS driver that has to do with networking/LAN/wireless and often is an indication that the issue is with your NIC/wireless card drivers.

    0xD1 errors are usually caused by faulty drivers. We need to read your minidump files.

    How to find and post your Minidump Files:

    My Computer > C Drive > Windows Folder > Minidump Folder > Minidump Files.

    It is these files that we need (not the folder). Attach to your next post the five most recent dumps. Notice the Manage Attachments button at the bottom when you go to post the next time. You can Zip up to five files per Zip; if you only have one or two you don’t need to zip them, just attach as is. Please do us a favor and don’t Zip each one individually.

    Also, what make is your computer?
