Two computers randomly reboot at same time

September 19, 2011 at 14:41:27
Specs: Windows 7
I have two Dell computers that are about 2 years old, same model numbers. They have just recently started rebooting at the same time...the exact same time when it happens. It is typically in the afternoon. Both systems are connected to separate UPS's so I don't think it can be line spikes. Thinking this may be sort of 'time-bomb' virus, I have run scans on both systems using Avast but nothing shows up. Any ideas?

How old are the batteries? When was the last time they were tested by unplugging the unit from the wall while under load?

I love a good conspiracy!

Hmmm a timebomb. Or a scheduler. Who else has access to these computers? Are you sure someone isnt playign a joke on you? Check Windows scheduler for actions that have "shutdown -r -t 0" in them. If these computers are on a network with others it could easily be done over the network - I do it all the time. See who else has admin rights on your computers.

Or maybe it is a timebomb....

If you suspect timebomb then set clocks 5 minutes apart.

Strong EMF/RMI might be causing it Any radar or fire control radar in the area?

I'd run a scan on the network to look for any suspicious activity.

I'd reload them both and see what happens.

1/3 of highway deaths are caused by drunks. The rest are by people who can't drive any better than a drunk.
