Explorer crashes randomly

[Stybar]

Hello,

The problem I am encountering is that my windows explorer crashes for no appearent reason. Windows itself keeps running, but when I'm going through my files I will randomly get popups that say "windows explorer has stopped working" followed by a message that "windows explorer is restarting," which it then does. Everything disappears, start button, taskbar, everything related to explorer, and then appears again.

Most of the time (99/100) explorer still works, I can click and drag windows or I can open folders and files while Windows is "looking for a solution," which makes me think that it's more a registry problem than a real problem with Explorer.

The problems first began after I cleaned up my pc, uninstalling games and useless software, deleting some personal files, and letting CCleaner clean up my registry. Also I had CCleaner do a "disk erase," something I never did before. When the problems began, I restored the registry using the backup CC created. The problem still exists.

It does appear to happen more frequently when I'm browsing my C:\Program files folder or my C:\Windows folder, but other than that there is no clear reason it crashes.

I know most of you will say that I should simply do a repair install of W7, but since I have no disk I have to use a iso, and since I am working on a Dutch Home Premium x64, there is no iso available. For some strange reason I decided not to make regular system repair point in the time I use this pc, so that's not an option either.

So if anybody has a direct solution, I would be infinitly grateful.

For any more information or specs, please do reply or send me a message.

Sorry, I fixed it myself already. I ran Shellexview, as instructed in this thread, and I discovered that dropbox was running havoc on my system.
Thanks for the quick reply nontheless, but it appears to be fixed now.

Edit: it isn't fixed. I thought is was since it stopped crashing, but it's failing me again.
I have run sfc /scannow, and the results are in the attachment. That's all I know, if you need more information, please explain what you need and how I can get it.
