Here's where I'm at:
I've got Gen 1 i7 that's currently my home server. It's running Windows 2012 Essentials. It has 8 HDDs (one is a SSD, for the OS), a generic old PCI video card (probably 10 years old), and 4 NICS (this was an experiment learning about NIC teaming). The power supply is 550 Wt Antec - I don't remember the specific model.
Recently, in the last week, it's begun to reboot spontaneously. It usually will stay up for a while - at this point I'd say 8 hours is the longest it will go, but sometimes less. When it happens, the Windows logs do not report anything odd. Meaning, if I go look in the logs just before the reboot, there is nothing listed. No errors at all. Just the logs for it coming back up again.
This happened almost at the same time that I swapped from WHS 2011 to Windows 2012 Essentials. I first installed Essentials about a week before this started. I don't *believe* it's the OS.
Things I've checked:
1) Memory. This was my first thought, so I rebooted and ran memtest for a couple of hours. No errors reported.
2) Drivers. This was my second thought. I guessed that some driver might be giving Windows fits, and causing instability. However, no driver changes have affected uptime, and I kind of believe the Windows logs would report a driver error or something before the computer went down.
I'm now looking for suggestions. Power supply possibly? Or some other part going bad? It's not overheating, as I've never seen temperature spikes or any kind of thermal warnings, and I expect it would completely shut down if that was the problem. Any ideas?
