Have an older Dell 7010 i5 used as a BI server that's randomly shutting down. As in hard power off say once/twice/three times at random times from an hour to several hours apart every few days or so. Other times will run fine for a week or more. No error, blue screen, etc. on shutdown that I've seen, just a hard quick down as if you'd hit the power button. No beep codes or other errors on restart. Not related to outside power loss, sits right by my desk and runs on the same power as several others. Not much running on it - BI and a few trivial servers (time, ftp, backup). Not running out of memory or disk. I've looked through various logs but don't see anything obvious. Is there a particular log that would track some sort of software/OS-directed shutdown or hardware shutdowns due to error/heat/etc.? Any ideas how to track the cause otherwise?
