Blue Screen Crashes with ntoskrnl.exe and tcpip.sys

  1. I'm running Windows 7 Home on a Lenova Laptop. I had had having numerous blue screen crashes in the last two weeks which dump indicated was always related to ntoskrnl.exe. (see dumps at bottom of this post)


    I ran checkdisk, Avast antivirus thorough scan, an anti-malware checker, Windows 7 memory check, then a two-hour memory check downloaded from Lenova, the manufacture of my laptop. No problems were detected by any of these programs.

    I went through all the drivers on my system as listed in the device manger and found no cases of red X. (There was one "unknown device" with a yellow exclamation mark.

    I ran Driver Booster looking for a fix and it updated 10 or so drivers

    The same ntoskrnl.exe crash continued so I restored my system from a backup of 11 days ago, which I think was before the problem started. I ran Driver Booster again and it updated 10 or so drivers. Before rebooting, I removed the "unknown device" thinking it might refresh. After rebooting I got yet another blue screen crash, this time pointing to both ntoskrnl.exe AND a problem with DRIVER_CORRUPTED_EXPOOL caused by tcpip.sys+75822. (Apparently driverbooster had introduced a new problem since I had not seen this error before? Not sure.)
