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.

Thanks, Andre! Sorry for the delay...I just saw your response then had to wait on another crash. Here's the dump file: http://cid-915a1ee2fa662a6c.office.live.com/self.aspx/.Public/explorer.exe.4240.dmp

i have a blank white screen to start, and nothing on it.then my comp. keeps blanking out. tryed fixing settings ,defragging, dcanning for viruses it's getting worse day by day.

Hi all, I have similar issues with explorer.exe frequently crashing with 2 machines (1 desktop, using Win7 64-bits Home Premium and 1 laptop using win7 64-bits professional). For one thing I know, win7 32-bits don't have this problem. The crashes happen when normally starting computer for 10 minutes till 4-8 hours. Restarting won't help; sometimes later, it starts crashing again. Once the crash started, it happen everything time immediately when I do the following: 1. Open a window to explorer local files. 2. Copy file , after press Ctrl+C 3. Click start menu, and trying to click some programs 4. anything about control panel 5. open task manager 6. and more, basically everything related to windows I got some windows log information (errors) like the following: Fault bucket , type 0 Event Name: APPCRASH Response: Not available Cab Id: 0 Problem signature: P1: notepad.exe P2: 6.1.7600.16385 P3: 4a5bc9b3 P4: StackHash_4a95 P5: 0.0.0.0 P6: 00000000 P7: c0000005 P8: 000007fefeb80068 P9: P10: Attached files: C:\Users\xxxx\AppData\Local\Temp\WERF680.tmp.WERInternalMetadata.xml These files may be available here: C:\Users\xxxx\AppData\Local\Microsoft\Windows\WER\ReportArchive\AppCrash_notepad.exe_a8f44f45c228efe271758ce8c01a7a1d933b8c_142b04b3 Analysis symbol: Rechecking for solution: 0 Report Id: d0f5beea-b9fb-11df-af76-1cc1de50ab37 Report Status: 81 I upload one dump file using above reg file. http://cid-9161437fdcddd898.office.live.com/self.aspx/.Public/explorer.exe.1200.dmp http://cid-9161437fdcddd898.office.live.com/self.aspx/.Public/explorer.exe.1340.dmp Machine information: Desktop, HP Pavilion p6510f Desktop PC , (brought 08/25/2010), AMD X4 2.8GHz, ATI Radeon HD 4200 integrated graphics, ASUS VH242 monitor; never re-configured.

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.
