I have suddenly started having a problem with the Windows Explorer Folder Tree randomly hanging up with no error message. I then have to end WE in Task Manager. At first after returning to WE all that would be shown was "Libraries", but since I don't use Libraries, I disabled them. Now all it will show is Desktop and Favorites, so I can't get to any other files on WE, or, more importantly, drives.To get rid of the situation I have to reboot after which I sooner or later have to go through the whole process again. I am using the following: Dell XPS 8300, WIN 7 Pro 64 bit, intel i7 processor quad 4, 12G RAM, 1T ROM.
Occasionally at the point WE hangs my file thumbnails become blank and sometimes even the non-system icons on the Desktop also become blank. So far the System Icons (Network, Computer, Recycle Bin, etc) have never blanked. I can usually get into the Tree without a hangup in other programs when using File. Open.
I have run Norton 360 and Malwarebytes (full scan twice each) anti-virus, sfc /scannow, checkdisk, Tuneup Utilities and the complete Dell diagnostic suite. None shows any problem. It is almost resembles a memory problem, but with 12 gigs of RAM that shouldn't be likely.
At this point I do not want to do a System Restore if at all possible.
Any thoughts will be appreciated.
