I am running the latest updated version of CentOS on a HP DL160 G6 server as a workstation with the Mate desktop, not Gnome. The only expansion card I have installed is a MSI Geforce GT710 graphics card driving two monitors. Unfortunately the computer locks up at random intervals: neither the mouse nor the keyboard work and I lose the SSH connection to the computer I have used to see if the entire computer locks up or only the desktop. If I leave the computer in this state it eventually reboots. Any suggestions on where to begin researching this? Thank you.

I am not familiar with edac.
