Explorer constant crashes; Not Restarting.

My explorer crashes from time to time, just randomly. Its not forced by anything I guess, it even happens if I close the lid of my laptop and open it again. It's just arbitrary. If i start "explorer.exe" or "explorer" from the task manager, nothing happens, explorer.exe flashes for a second in the processes tab and then disappears. I am attaching some dump file which I had created using this link (5th post by auggy, telling to create a registry file)

I dont have the software to go through the dump files, so please help me find a solution.
I am in no position to do a reinstall of Windows (win 7 x64)

please review

bing!

I had a doubt. I am not getting any BSOD, its just a random crash of explorer. The taskbar disappears and (sometimes) comes back but without the battery, network, sound options in the system tray. So, without BSOD are there any minidump files being created?
