I need some help. I am running ClearOS Community edition. I loaded this new vesion about 2 weeks ago and the PC I am using hangs up about every 6 or so hours. Sometimes sooner sometimes later. I am running a Dell OptiPlex 745. The monitor goes black and the keyboard and mouse are unresponsive. Any ideas as to what the reason could be..

The system went down yesterday around 16:02 on Sept 12th until about 7:58 when i rebooted. I rebooted on 9-13-2019

This has been going on every single day. Any suggestions?
