I've got an Optiplex 740 here under warranty. I can get any part I need overnighted here to get it fixed, but this one in particular isn't a consistent problem to track it properly. It powers down randomly. Sometimes it'll run for weeks, other times it'll run for 10 minutes and shut down. It's a pain when a student is taking a test on it and the darn thing shuts off, so I pulled it from the lab.
My PSU tester comes back with the proper voltages, but my PSU tester was also 6 bucks at an expo center last year so I'm not always 100% confident with it.
The only other symptom I've seen is the fan speeding up every now and then. But even still, how do you troubleshoot that? It could be the PSU since it's what powers the fan or it could be the mobo because maybe the controller is fried.
Thoughts?
