So, I came home the other day, and all three of my computers had been restarted. When I turned the monitors on, all three were at the logon screen. I have three desktops connected to the "infronet" and each other through a Linksys router with wireless G. The thing is that the wireless is disabled when not needed, and it was off that day. Before, I've come home and one computer would have been restarted, but not more than one. I had previously thought that the heat got to them, and they shut down. But they weren't shut down, just restarted. And, to add to the heat theory, it's winter time. Should I post a "Hijack This" log? All antivirus, and malware scanners come up clean.

What do the Event Logs show? Are they all on the same circuit? Perhaps it was something as simple as a power surge. Do you have them connected to any type of UPS or surge protector? Life's more painless for the brainless.

could it be wake on LAN?

It must b something to do with power surge... also check logs. nb Free web hosting providers list is here
