I have had similar spontaneous shutdowns that were unexplained till I realized they were actually caused by the APC UPS's in my lab/office. One did it nearly daily till I just happened to be there to observe it and realize what was going on.

I have my own AC and keep the server room around 68 or so. Good airflow. No dust build up inside the case. I'll try swapping the power supply itself with a known good one to see if that helps.

How is the circuit load? From: Kyle Plummer [mailto:kplum...@nje.com] Sent: Tuesday, April 20, 2010 3:46 PM To: NT System Admin Issues Subject: Spontaneous server reboots I have an HP DL380G4 server that randomly reboots. At first I suspected an issue with Windows. However, I booted into the BIOS and let it sit there for a few minutes. Again at random intervals the system will reboot. Sometimes I can't even get all the way into the BIOS. I replaced the memory modules with new ones (twice, just to be sure) - still reboots randomly even from the BIOS. I suspect an issue with the motherboard. Any other possible causes, or has anyone experienced this with the G4's? It had run for about four years prior with no issue until this started. No other hardware changes or updates to the BIOS have been done in the last year (only Windows patches). Thanks in advance, Kyle B.
