Bad driver install BSOD on startup

  1. My wireless card has been acting strangely lately so I tried to install the new driver from Intel's website. As soon as I installed it (during the installation process) I got a BSOD. Now every time I turn on my laptop it is extremely sluggish, and gives me a BSOD within 2 minutes of Windows startup.

    Everything works fine in safe mode, including the wireless (after installing a different driver from my laptop manufacture's website). But I can't start up in regular mode without the laptop freezing up and giving me BSOD.

    I'm fairly certain it's this faulty driver that is causing the issue. I have never overclocked at all, but my laptop did suffer from a overheating incident which was never really addressed by Sony mechanics.

    Here is a link to my minidump:

    I tried to attach it but it said the file was over the limit.

    The dump does not point to anything specific, unfortunately. Just a generic BSOD, as far as I am concerned.

    Your Intel WiFI drivers are a version or two out of date:
    NETwNs64.sys Wed Jul 14 07:42:54 2010 (4C3DA2BE)
    I suspect you can find some more recent ones. Download the latest ones, and then uninstall your current ones in Device Manager.

    Reboot, then install the ones you downloaded.

    Now I see you have SPTD running:
    a8kt92pl.SYS Tue Jul 14 17:12:55 2009 (4A5CF4D7) -- a driver dynamically allocated by SPTD
    sptd.sys     Sun Oct 11 16:55:14 2009 (4AD24632)
    I have seen SPTD cause a machine to get incredibly slow, like you are describing. In addition, I have seen SPTD cause hundreds of BSODs, literally. I could provide perhaps a dozen links if asked.

    Remove Daemon Tools, Alcohol 120%, or whatever similar program you are using. Those program use SPTD. When you're done, remove SPTD with this tool:

    How has your wireless card been acting up? I see no anti-virus program running, so that makes me a bit nervous. I recommend downloading Microsoft Security Essentials, and then immediately running a scan.

    Finally, I recommend a system restore if these steps are not productive.

    Unfortunately I shut off system restore long ago to conserve space due to the fact that my laptop only has a 128gb ssd hdd. I can't get into my normal windows so trying to uninstall any programs in safe mode is a no go.

    I have had a anti virus program running, panda tools, but only recently. My wifi kept cutting off before but it was a known issue with my laptop driver. One day the wifi wouldn't turn on at all so I tried to update the driver and this happened.

    Now I can't even make it to the windows screen, after login my laptop automatically shuts down.

    Try booting up in Safe Mode.

    If you can, uninstall your networking drivers, and then reboot into normal mode.

    While you're there, check in C:\Windows\Minidump, and see if there are any .dmp files. If there are, boot up in Safe Mode with Networking, and upload them to us.
