Ghost 10 crashes system during Copy Disk

I've been using Ghost to back up my pc for a couple of years.  Periodically I run Copy Disk for a full backup on two external drives.  I then store one offsite and run a daily backup to the other one.  Recently my system has started crashing whenever Ghost is running.  The system completely freezes and I have to do a power off to re-boot.  I have run Disk Doctor, Check Disk, Anti-Virus, Malwarebytes, reformated both external drives, and reinstalled Ghost, all to no avail.  But oddly, I was able to Copy Disk from one external drive to the other external drive without crashing.

 

Help, I'm stumped!
