I checked the graphics card, RAM, hard drives using the Dell hardware utility stress tests.
All drivers were up to date.
I had restored my PC back from available Windows updates but no change.
A utility for explaining a BSOD (Blue Screen of Death) 0 x 1000007F Unexpected Kernel Mode Trap showed that a mfehidk.sys was recorded in the log which is a McAfee Total Protection 2014 .This file is a link driver and leads me to believe that the BSOD which occurs when I try to drag and drop files or move up to the root directory was probably caused by the McAfee anti virus product.
Disabling the McAfee functions seemed to cure the problem immediately
Contacted their technical support who did seem to be familiar withy this problem. They found that Microsoft Security Essentials was also running which is not a good idea having two AV software running.
They then checked the Network Driver for updates which was found to be up to date.
Running the McAfee virtual technician showed no problems.
It was however suggested that a complete removal and reinstall would be necessary and offered to do this remotely for me.
The Remote assistance removed all McAfee products using mcpr.exe and rebooted.
They set up a reinstallation link on the desktop and serial number and asked me to reinstall and see if the error reoccurs.
July 2014 everything has been OK.
To clean and re-install Mcafee Total Protection 2014 I have detailed a home use procedure below.
