Explorer.exe stops working

We have 1 user that is having an issue with explorer.exe. A couple of times throughout the day, she will no longer be able to open or click on anything from her desktop. If I go into Task Manager and end the explorer.exe process and then start it again, it will begin working. This just started a week ago and I don't see anything in the Event Viewer that would cause it.

Something must of got corrupted on an update.

I would run CMD in an elevated administrator prompt and run SFC /Scannow to check the system files.

Also run Chkdisk -r to ensure there is no disk corruption.

I'd run virus and Malware scans.

i would run a diag on the disk drive  - best use the manufacturers diag
for this i use the uBCD a lot :
Hardware diagnostic CD    UBCD
---------------------------------------------------
go to the download page, scroll down to the mirror section, and  click on a mirror to start the download
Download the UBCD and make the cd   <<==on a WORKING PC, and boot the problem PC from it
Here 2 links, one to the general site, and a direct link to the download

since the downloaded file is an ISO file, eg ubcd527.iso - so you need to use an ISO burning tool
if you don't have that software, install cdburnerXP : http://cdburnerxp.se/

If you want also the Ram tested - run memtest86+ at least 1 full pass,  - you should have NO errors!
 
For disk Diagnostics run the disk diag for your disk brand (eg seagate diag for seagate drive)  from the HDD section -  long or advanced diag !  (runs at least for30 minutes)

**  you can make a bootable cd - or bootable usb stick
