    BSOD - SYSTEM_THREAD_EXCEPTION_NOT_HANDLED (nfsrdr.sys)


    For some reason, my laptop has been acting up recently. About 3 days ago, I attempted to install the Java 7 Update 11 (x64) on my laptop. After shutting my computer down and then starting it the following day, I logged in to my user and, after 10-15 minutes, a BSOD appeared. I then decided to restart my computer, and, just like before, a BSOD appeared that said:

    SYSTEM_THREAD_EXCEPTION_NOT_HANDLED (nfsrdr.sys)

    Afterwards, I restarted my PC again and decided to restart my PC on Advanced Start-up via PC settings and access System Restore. I was able to do that and, for about a few hours, that worked.
    However, I foolishly decided to use hybrid boot again (I switched it off before because my computer was not implementing updates properly) and after restarting and clicking the lock screen, I had a hanging “Please Wait…” notice and it would loop back to the lock screen and, when I clicked the lock screen, I got “Please Wait…” again. Sometimes I was able to see my account on the screen and, when I got the chance, I accessed my account removed hybrid boot and everything went back to normal… temporarily.

    Today, I got the same BSOD even though I haven’t installed anything and, upon restarting, the same stuck “Please Wait” loop that I thought I fixed even though I don’t have hybrid boot on. I was able to fix the latter problem by unchecking Hibernate and Standby in the Power Menu before restarting my computer. In fact, I thought Hibernate and Standby were the problems so I checked them again and restarted my computer, but everything was normal and I was able to log into my account without a hassle.

    All I know is both issues have something to do with the nfsrdr.sys file in System32. Hence I followed the instructions on the BSOD and Crashing Thread tutorial and attached a compressed set of files from the SF Diagnostic Tool.

    One more thing: I believe that this same problem also has to do with the inability of the Windows troubleshooter to repair Windows Update problems. I have troubleshot Windows Update several times and got the same responses for the errors (shown in the screenshot below) supposedly fixed. I think it’s something to look at.

    I apologize for being impatient but I would appreciate if somebody would solve my issue as it has been a day and a half since I posted.

    On a lighter note however, I found out what causes the BSOD: connecting to a wireless network.
    However, I was able to boot into safe mode with networking and I was able to connect to a wireless network without a BSOD. I tried repairing my WLAN driver (Intel Centrino-N Wireless) but that didn't prevent a blue screen from occuring when I connected to a wireless network.

    That's all I know so far. Any help would be appreciated.

    113 views and not one reply from someone besides myself? Did I do something wrong?

    No, many people look to see your issues, but there is only around 10 debuggers.

    Heres what I suggest;

    • do a "sfc /scannow" in commandprompt
    • update your wireless driver

    Lot of network errors which are usually caused by stubborn antivirus software.

    Uninstall Norton, google its removal tool and make sure all drivers from norton are gone away from your system and then enable the default antivirus of Win 8.

    I removed Norton and tried the sfc scan and even updated my WLAN driver but none of those worked. Is it possible for someone to just copy the nfsrdr.sys file and paste it in this thread? Mine was last modified on 7/26/2012 at 5:25 AM and has a size of 257 KB. I'm quite sure anyone else who has the US version of Windows 8 has the exact same specs for this file.

    The driver will only work with your system since its been installed and configured that way.

    In that case is there any other way to fix this error besides formatting?

    In addition, I found information from the event viewer about what caused the bluescreen.

    I was stuck on the same problem for a month and could not find any answers to the problem. I finally figured it out so thought I should share so that others who are in my shoes do not waste time.

    The issue is due to any mapped NAS drives hosted on Linux based kernel and if the Client for NFS is installed on the windows machine. For some reason this configuration does not work. If you mount your shares and NFS is installed it tries to use the NFS client and fails miserably. Trick is to unmount all shares by logging into Safe Mode and then rebooting and uninstall NFS client and then mount your shares.

    I just did and my server is back stable. Hope this helps someone.
