HP DL320 Gen8 Server Hang

Good day with everyone.

I have an HP ProLiant DL320e Gen8 Server that crashes every 72 hours, that is, the Network Administrator must go to the Rack, disconnect the power and turn the Server back on again.

The Server does not present alert on hard disks and power supplies.

Please, I have the help in how to make the diagnosis, causes of the failure and solution.

Thank you.
