I'm looking for a program that will log the last time the computer was rebooted. Not how fast it can reboot, or why it will reboot, the exact time, in a little text file. Blah Blah, was shut down at 08:36am. My computer is shutting all the way down, I've been through EVERYTHING with heat, temperatures, BIOS and CMOS regarding timers, Windows Power Settings, and hibernation, and can't find ANYTHING. And it's a complete clean shutdown. I don't lose any data, and have never had Windows warn me on boot up it was shutdown improperly. I was hoping that the Event Viewer would do it, but that's only if Shutdown Tracker is on in Windows, and a user reboots the system. For example, I'll leave for work, come home, and its off. Lay down for a nap, wake up, and its off. Completely confusing!!! Add me to the millions with computers that inexplicably shuts down, won't start, constantly restarts, etc. Ugh, never EVER had a problem with my machine doing any of this in my 14 years experience, and now XP is doing it to mine, now. I guess a re-image is probably the next best thing. Test to see if something I installed things its funny to shut down... 'Oh, he didn't need that' Click..... Just please contact me if you can supply a little freeware program that tells me the last time my computer was shut down.

What does it say in event viewer logs? "Best Practices", Event viewer, host file, perfmon, antivirus, anti-spyware, Live CD's, backups, are in my top 10

Nothing at all. As an example. I'm in Eastern USA, Time is now 3:51pm. Approx. 1:00pm, I laid down for a nap... Woke up approx. 2:45pm, and machine was down. Above is for a time line, so it obviously happened sometime between 1:00pm, and 2:45pm... Event Viewer Application shows: Last entry at 9:39am, (when a Java update was installed, after that, next entry was all of the system service start ups at 2:56pm Event Viewer Security is empty: Event Viewer System shows: last entry this morning at 9:49am, and not again until 2:56PM, is there another 'Information' entry... Microsoft office diags show nothing, and Sessions just show my sessions, and that I closed them. Internet Explorer is completely empty: Antivirus shows that yesterday sometime it got an update. Hope that helps! ~~Question I have, is if I turn on the Shut down Event Log, and windows is forced down, will it make a log of that? Maybe I'll enable shut down log viewer, see what happens...

You could probably use 'Last Chance' (http://www.snapfiles.com/get/lastchance.html) to run a program at shutdown, maybe a batch file to create a file. Then you could check the time that the file was created. But I'm not sure how that would help. But how about checking on a Screensaver that might be doing it. You could try using msconfig/startup tab and deselecting applications, to see if one of them is doing it.

I think I may have finally found it. I turned off the Avast Anti-virus screen saver, and no problems for more than 36 hours! Thanks to all who answered and kudos!
