Explorer.exe Crash on Win 7

2996 Views 3 Replies 2 Participants Last post by  usasma
Well, after searching and trying stuff for the better part of the day, here goes:

My explorer.exe crashes every... 1min? maybe 2 but only if i use it
Noteable times: when i press the back button, or when i go to C:\ from "My computer" is when it ALWAYS crashes, but still it seems random cause it works fine if i just type "C:\" on the path of another folder. Sometimes it can even crash if i just open 2 folders or even click the desktop if i havent used it for 5mins or so! (using my virtual Ubuntu :p)

It did started happening after an auto update but i checked the update log and it was all about "malicious software removal" and office updates...
Also havent installed any software when this started happnening... damn autoupdates... i was asleep

error details:

Now, i have looked around and tried stuff i thought could help. Here's what i've tried:

*Virus checks: NOD32 & Avira, tried them both and made a full scan... well that took a while. Also have UnHackMe, and HijackThis log seems clear
*tried replacing explorerframe.dll with another (same version)
*did a chkdsk on both drives, it was a good hit on google but... :\
*No disk fragmentation, also a hit on google
*Registry cleanup etc with tuneup utilities
*I've disabled all services except those listed as microsoft in msconfig
*Uninstalled nvidia drivers and disabled aero (im with win classic now... havent seen it since XP :p), nothing
*New nvidia drivers, nothing...
*sfc /scannow

Also it seems explorer.exe doesn't crash in safe mode, so ill also try to disable some microsoft services from msconfig, it will take a while, so ill update this
once im done

I could use any ideas right now cause its getting anoying running stuff from cmd :rolleyes:

PS: no hardware changes for a month or so also... i've deleted my restore points a few mins before autoupdate thing :eek: shouldn't autoupdate make a restore point!?! ***

ninja edit: oh... bit of a long post isnt it? Sorry guys, thanks for reading this far though

Registry cleaners can cause problems just like this - don't use them anymore.
Here's an article explaining why:
FYI - the article was written for XP, but it also applies to Vista/Win7

If it doesn't crash in Safe Mode, then (as you've surmised) it must be something that loads in normal mode and not in Safe Mode. I'd suggest using this free tool to see what loads with explorer.exe (a lot of stuff!):

Most commonly this is caused by shell extensions - so here's a freeware tool for viewing them also:

If nothing shouts at you, it'll probably be a matter of disabling 5 to 10 and testing, then another 5 to 10 and testing, etc

Good luck!

Thanks for the reply usasma, i had already checked with shexview for shell ext.s that shouldn't be there

Anyways it was usual PEBCAK, instead of disabling all services and testing 1 at a time,
it did the checking... the other way (disabling only one at a time) :\
Problem was 2 services and another process! The daemon tools process and 2 services from CISCOs Network Magic
Reinstalling them didn't fix the problem, but since its gone now, ill keep poking around

I will update if i find any fix for those two programs
Glad you discovered the cause(s)!

We see lot's of BSOD problems with Daemon Tools and a few from Cisco stuff.

Good luck!
