So I ran my usual CCleaner like I do every week. I do not clean the registry. I only clear the temp/history/cookies/etc.

I restarted, loaded up all my stuff and got up to mix. I came to my PC for a second and went to type a song name in the start search bar, and as I was typing it said "Explorer.exe has crashed". It recovered afterwards almost immediately, but why the hell did it crash in the first place?

It has never done this. I left my computer on for like two weeks, during those two weeks I played games and everything you would normally do and it never happened. I've had my computer for almost a month and a half and it has NEVER done that. My overclock is 24/7 stable and has never crashed BSOD'd etc. My rig has never BSOD'd, etc.

Was it just one of those stupid things that sometimes happen in Windows for no apparent reason? Like I said, this is the first time it has happened.

Check your SMART on your HDD.
My HDD was acting funny the other day... When I checked the SMART data. It had bad sectors. I was wondering why explorer etc would crash.

an old trick I'd use 5 years ago when all I had was 1 dying 120gb drive was to ctrl+alt+delete kill explorer.exe and then go file>run "explorer.exe". It does nothing but restart the Windows GUI. its probably a lot less harmless than leaving your computer on for 6 weeks, no offense.

Probably malware. Much more likely if you run as admin all the time. Do a System Restore if you can.

If it *is* malware, a local scan probably won't work. Try scanning with the Kaspersky boot disk.

It's not malware. I also do weekly scans of MWB, never shows anything. I browse the web with Noscript, and I'd like to consider myself very smart with computers. I always check my processes to look for suspicious activity.

I'm paranoid, basically. It's not malware.

I've actually never checked the health of a HDD before, how would I go by doing that?

Afterwards type chkdsk and when it says if you'd like to run it after reboot, say yes.

See if those fix anything for ya

It's possible it was just a weird crash, I've never really seen that before though so I was a little concerned.

CrystalDiskInfo

It's free and open source

Go into Event viewer -> Windows logs -> Application, and see what it says, i would filter by date so it's easier to find it, and the level should be Error.

Got it, not quite too sure what that means, though.

All I know is Shell32.dll is a legitimate file and is located in the correct folder... aka Sys32.

All i can think of is if you customized the icons within shell32.dll, and that's how it happened but i highly doubt that's the cause.

Yeah, no idea. Here's the only changes I made recently.

Moved all icons to taskbar in Windows 7
Deleted all other stuff on Desktop that were unused/unnecessary shortcuts
Made a recycle bin shortcut and added it to the taskbar
Hid icons on desktop

I doubt it'll happen again. Since it's a legit DLL I have absolutely no idea what could have caused it to crash.

Just a question, do you have thumbnails preview on? I remember one time explorer.exe kept on crashing on me if I went into a particular folder. It only had a bunch of things in it like pics and songs. I later found out that it was a corrupted thumbnail/s, after clearing the thumbnail cache it was okay again. Sorry I cant link you a source on the procedure but im looking it for it
,

EDIT: lols I just remembered its under disk cleanup, that option should also be available in cccleaner


Hope that helps

Wow dude, that might actually be it. Just cleared the Thumbnails. Also, how would I disable Thumbnail previews, period?
