    explorer.exe crashes Windows 7 Professional


    We are seeing explorer.exe crashes on 3 PC's right now...all 3 are Dell OptiPlex 755's running Windows 7 Professional 32-bit. I have attached the dump file that was created using the registry program that was provided in this post. We have already tried sfc /scannow, chkdsk and virus scans. Thanks for the help.

    I see that the default on those machines are Windows Vista. I am assuming that you purchased Win 7 and did a clean install?

    Correct....we actaully used Windows XP Professional originally.....then we created a Windows 7 master and transferred data back over to the new Windows 7 hard drives

    Hello and Welcome !

    Seems like SnacNp.dll i.e. SNAC Network Provider which belongs to Symantec is causing the explorer to crash. I would recommend to uninstall it. Then run SFC /SCANNOW Command - System File Checker

    Bucheck:
