I recently inherited four old Core2 Duo desktop machines from work who were replacing them and giving them away. I've distributed three of them around members of my family to replace ancient old machines, while I was going to use the other as a home media server.
They all seem to work fine when powered on, but they also all seem to behave oddly while shut down. Every now and then, apparently at random, they will power on for a second or two - the fans will spin, lights will flash - then shut down again. If I press the power button they all power on with no problems at all.
I suspect this might be some kind of 'wake on LAN' type behaviour, but I've never had any experience of configuring this so I don't really know how to go about fixing it. There's also the worry that it's a sign that the motherboards are about to die.
Does anyone have any ideas what this is and should I worry about it?
