Windows 7 64 Bit Pro Explorer (explorer.exe) keeps crashing and restarting randomly. This happens several times a day and its quite annoying. Sometimes happens when I search for files, sometimes when I click on an Program Icon, Sometimes when I open a folder and sometimes for no apparent reason. My Install was a Clean Install and I have had this issues from day 1. I have tried several “solutions” including Copying Explorer.exe from the Wow64 folder to System32 folder, fixing the SQM issue, Changing registry settings, Running sfc, Defragging my HDs Scanning for Viruses and Malware (using Multiple fully updated AV programs). Updating Windows and Drivers etc. etc. Nothing seems to work. I don't want to reinstall the entire OS if I will have these problems again. Please Help! Thanks. K. Chahal

A not-dissimilar situation has shown up in a couple different places, related to the nVidia M series video adapters. Apparently they have a mechanism whereby they flip in and out of high-performance mode depending on what's being demanded by currently running software. The problem is that in certain situations this switch can happen several times within a few milliseconds and create problems for Windows. (I've only seen this come up in relation to 64-bit versions.) The fix, copied from an OCZ forum, came courtesy of Winston Smith: Update Driver Download and install the latest NVIDIA driver from here . RivaTuner Download and install RivaTuner from here . Magic Open RivaTuner and switch to the "Power User" tab. Expand the "RivaTuner\NVIDIA\Overclocking" Tree. Set "EnablePerfLevelForcing" to 1. Switch to the "Main" tab. Under "Driver settings" click on the small arrow left to "Customize..." and choose the first icon "System settings". Set "Force constant performance level" to either "low power 3D" (suffient for 2D audio work) or "performance 3D" (used for 3D gaming). Click OK and let the computer restart. I would start with step 1, update the driver, then if the problem persists download RivaTuner and continue from there. This even handles a problem of Windows 7 x64 (or Vista x64) freezing completely under certain circumstances on the MacBook.

You have a Heap Corruption in Shell32.dll

Please run ShellExView and disable all Shellextension which are NOT from Micrososoft. Does the crash still occur? If not, enable the extension successively until you find the one which crahes the explorer.
