Find the problem of Automatic restart

by mohammadyou / February 22, 2012 3:54 PM PST

Hi Everybody,

My computer is running on Windows XP and I use Nod32 as well. after refresh installing my windows the problem came up(and upgrade bios firmware). the computer automatically restart at 3 am ??!!
I thought that it's because of automatic update so I disabled windows automatic update (and enabled the related policy for preventing automatic restart as well).
but I still have the problem.( I have unchecked automatic restart for system failure).
How can I find where the problem stem from?
is any software to track down the problem.

Thanks in Advance

If the system is re-booting ...
by Edward ODaniel / February 23, 2012 5:53 PM PST

every day at the same time (3:00 o'clock AM you said) then it sounds like it has been scheduled to do so.

Look over this link and see if you have any scheduled task running the command shutdown.exe -r -t 00

If you do disable it.

If you are using Windows Server Update Services (WSUS) at your location the default time for the scheduled install is 3:00 A.M. once a day, and if an update requires a reboot in order to complete installation, the client will automatically reboot (if some update keeps failing to install it could cause the daily re-boot). In that event this might help but you would still have to hide the update so it wouldn't be attempted.

Boots can't be initiated by XP if the computer is turned off, because XP isn't running then. But they can from the BIOS. So check the BIOS setup for a "wake" event at 3 AM.

No I don't have a problem with boot. the problem is my computer automatic restart.
I use this computer as CCTV and should run 24/7 without any time-out.

Did you check

In reply to: Re: automatic boot

the Task Scheduler as offered by Edward?

If not that, and if it is not WSUS, then look for any other software that might be updating at that time.

Other than that, why not a test? Make sure you are awake and at the computer at 3:00am one night, and watch what happens at that time.

Ohh, and you could check the Event Viewer. Since this happens every night at 3:00am there should be regular entries for that time in the System log, but I would also for good measure look at the Applications log as well.
