Intermittant shutdown 1

I have an Asus A7V333-X motherboard with an AMD2600 processor. OS is XP Pro. It is about 4 years old and has started intermittantly shutting down and then restarting. The logs do not show anything strange. The power supply was changed, the processor was changed and the processor fan was cleaned. The processor is now running at 55 degrees C where it was running at 65 degrees C. The Hard drive passed the Maxtor tests and the OS was reinstalled. My next guess is to replace the motherboard. Does anyone know of any logs that can be created to monitor this better than the event viewer logs?
 
When it reboots randomly, are you getting any error messages or blue screens, or is it just a total black out and restart?

Also, you replaced the power supply? When you did, did you replace the power cord as well? If the power cord has a short in it, this can easily happen, or if there is some bad wiring comming to the computer. Have you also tried running the computer from a different outlet, possibly a different room or building just to see?

Do you have any extra peripherals (PCI acapters), video cards, etc, that you could run the computer without, in order to make sure it isn't one of them causing the problem? It wouldn't be a bad idea to test running it with nothing connected that isn't necessary. If you have onboard video, try running through that, without the video card (assuming you have an add-on video card), and without anything else connected. Just so long as it will run.

If you check all of that, and still rebooting, then my guess would be yes - the motherboard. There could be one little minute piece in the motherboard such as a compressor to go bad, and then you're best off just replacing it. Besides, for a 2400XP (assuming it's an Athlon XP) processor, you can get a new board cheap enough.
 
I am using it to monitor and record 2 video cameras 24 hours a day. When it reboots it goes right back to monitoring the cameras maybe once a day maybe twice. I loose about 1 minute of video recording time each time it reboots. Not a big deal just a little irritating. No onboard video. It was doing this before I started using it to record video. I did not try the power cord I think that will be the last thing I try. I don't think it is worth much more troubleshooting time. The motherboard are only $50.00 now. thanks
 
Hmm, that doesn't sound like a "reboot". If it rebooted, it wouldn't go directly back to monitoring the cameras if you have an Operating System installed such as Windows XP.

My guess is that you have hibernation and/or standby enabled on your machine, and that would also explain this occurance. To check, one place you can look is under your power management. Probably the easiest way to get there is to right-click on the desktop, choose "properties", go to the "screen saver" tab, and click the "power" button. There is a tab there about hibernation. You could disable that and see if that fixes your problem.

It would if the monitoring software was running as a service or if it was listed in the Startup folder.


 
You should be able to tell from the event logs whether or not it is truly rebooting. Under Event Viewer, go to the System logs and look to see what is being logged at around the time that the system "reboots". If there was a crash/reboot, there is usually a message that says "The previous system shutdown at TIME was unexpected." If there was a graceful reboot, there would still be an entry when it came back up that says something like "Microsoft Windows blah blah Service Pack blah uniprocessor/multiprocessor free." On my current system those are event IDs 6008 and 6009 from the Event Log source.

If it truly is sufferring unexpected reboots, the only other thing that might be worth checking (merely to confirm that it is the motherboard) is for leaky or bulging capacitors which can be causing problems with power delivery.
 
There are no indications in any of the event logs that the system has had a failure or has shutdown. The computer is set up to restart in the event of a power failure and the monitoring software is set to reload each time the computer starts regardless of why the computer restarted. I have two computers side by side and will be working on one and watching the video on the other one and while I am watching the computer will restart. I have not checked the capacitors as I will not change them even if they are bad. A new motherboard and processor is $150 and I can use all the other parts and have a faster machine so it is not worth the time to repair a 4 year old board.
 
Have you tried taking all of the pci cards etc. out and trying them in a different computer, or running a burn in test with out them in.
