Unexpected Restarts

Hi Guys,

I was hoping someone could shed some light on a problem I have been experiencing for the last 10 days.

My WIN 7 x64 PC keeps restarting itself every night at 12:13:14 AM for no apparent reason. I have no scheduled tasks that could be triggering this. It appears to be a fairly graceful restart.

I have completed multiple malware/anti virus scans (Kaspersky, FSecure) to name a few. Downloaded some rootkits which yielded nothing, created a new Admin profile and disabled the old one, yet still it is restarting itself.

Any ideas would be greatly appreciated!

Information below,

Thanks guys & gals!

Hi nobus,

Thank you for your response.


The last MiniDump appears to be 13/9/2012....so not much to go off there.

I've checked the event viewer a few times for things that could be happening around that time, but have yet to come up with anything significant.

It's just bizarre that it is the same time every night, right on cue

Thanks.

it looks like there is something scheduled for that time, do you have any tasks running?

if you connect a 2nd pc to that AC line, does it restart also?

web_trackerCommented:
I would thinks of updates that are scheduled to install at that time. Maybe a group policy thing on the server is installed so that updates are installed and the computer is rebooted at that time. For example this pc may be part of the managed group... where all computers listed in this group automatically have updates installed at a specific time and the computer would automatically be restarted to apply these new updates.

I'm having this exact same problem. I have no tasks set that would restart the machine, and no update schedule for that time. We did, however, have a Conficker and FTP.bat infection, but both of these have been cleaned and removed.

All the other symptoms are the same, same restart time, same message, everything.

Can anybody help?
