I am not sure if this is a known issue and i am out of ideas as what to search for answers. I have a 3,1 Mac Pro that is running El Capitan for about 6 months now the computer will randomly lock up when i try to move files or delete something from the desktop. Most recently i tried to unmount a DMG file and the computer will just spin the beach ball. I will have to force turn off the computer. I can still launch apps and mess around on Safari but if i have to do anything on the file system it will not work. What could be causing this. I have recently replaced the HD that has my OS is on and upgraded ram. The HD is a SSD and the RAM is out of old servers which unfortunately are the 667 MHz speed.
Any ideas or suggestions would be appreciated.
Thank you
