I was wondering if the Debian gurus can assist me and at least point me to the correct path.

My issue: I have a fast computer with multi core CPU, maxed out RAM 32GB and more than enough hard drive space for any kind of application / process to execute and process data without any issues...

But I find that my computer freezes and restarts without any prompts, error message or any kind of warning messages... and all of these happened randomly, without any kind of patters and/or sequence... there are days that I absolutely have no issues with my computer... my computer would run day and night 24hrs without any issues. However there are days that I get a tester back to back and I only hear the computer fans running... no post... no videos and no display on my monitors.

Does anyone have any idea what the issue might be? Were or what I can look? I’m thinking it might be a memory issue, then again I might be wrong.

Thank you for all the advice and suggestions... greatly appreciated it.
