Appreciate the response.
Here's the plan:
I'll make sure bios is set to stay off in the event of a power outage.
I did run memtest when I set it up, but I'll do another just in case something else has gone wrong.
I just bought that SATA controller for this server - I can get a different one - where can I find recommendations?
I'll check the bios's Power Supply Idle setting! Have no idea about what it's set to. (All defaults)
Thank you again for the response. At least now I have something to look into.
