    Computer shuts off at 10:30 every night?

    So one of my computers just randomly shuts down at 10:30 at night...seems to be every night. It was at 10:30, 10:29, and 10:33. There is no program set to shut down the computer...it's doing it by itself.

    Why would this be? If it was windows update, it would have a pop-up screen/installing new updates. There isn't a warning or anything....so I am guessing it's not that.


    Thanks

    Does it shut down at any other time other than around 10:30? My first thought was the MyDoom virus but I'm pretty sure that'll randomly shut down your computer, not at a specific time.

    Well, for some reason it doesn't want to boot up after it's shut off itself.

    The computer turns on, but the monitor doesn't show anything.

    Somedays the computer works....it's not like the HD died, it just sometimes works and sometimes doesn't.

    That's the time I switch my lights off at night. Hmmmm.

    Seriously, iirc, there is a setting to do that in Windows, I think. If you right click on the desktop and go to properties. Under screensaver or something you can set power management and hibernate and so on. Isn't there a setting for power down? I don't use Windows anymore so I'm going from memory.

    Yes, but that setting really doesn't mean anything now IMO. That is the turn off monitor/hard disks/system standby after an X amount of minutes of inactivity.

    When I just try and start the computer nothing shows up...so it's not inactivity.

    I'll be doing something on my computer and then it'll just die.

    By chance are you doing something intensive on the computer when it shuts off? Video Editing? Gaming? If so, the extra load could be causing the shutdown and nonrestart problem..

    Consider burning a LiveCD, and run scans from there.

    Knoppix is a very good one, and will work fine if you're running XP. If you're using 2k, or have less than 256MB of RAM, go for Xubuntu, which I think has the scanning tools, too...

    You can leave Knoppix running as long as you want, and it doesn't affect Windows unless you specificly tell it to go "rm rf ~/*" in the terminal (command lines). If the PC still shuts off at 10:30ish, it's a hardware problem. If not, it's a software problem.

    So run knoppix, and see if it crashes at 10:30?

    check the event logs to see if anything funky is going on at that time.

    @Mark: Yeah. Knoppix running as a LiveCD is an entire operating system, so you can continue to do your work from it while waiting. You might have some problems if you're using Dialup, but it should workout fine.

    You'll need to burn the 680MB~ file to a CD or DVD (at x4 speed prefferably) and then boot up your PC with the CD in the drive. The .iso file (don't open it at all, just save and burn) will take a while to download. I think even via Bittorent it can take something like 6 hours. You can buy a burnt CD from some stores, or get one from a Linux User's Group near you for the cost of a CD.

    If it doesn't work, restart, but hold DEL, F2, F3, F4, or something at bootup, when you should see a logo or some general info. It will bring you to the BIOS. From there you set CDROM/DVDROM/DVDRW/CDRW as boot point 2, floppy as boot point 1, and hard drive(s) as boot point 3+. Then reboot, and it should bring you to the Knoppix login page.

    And if it fails at 10:30, I suggest calling up a hardware technician and inspecting everything. Otherwise, it's just Windows with an infection/malfunctioning setting.

    Alright, what's happening now is that it's just dieing, but it keeps running.

    Haven't done the knoppix thing yet, but the monitor just dies, everything shuts off (I assume, I go offline MSN etc)...but the case is still "running".

    That's an odd event. Since the power supply unit isn't dying, but the monitor is and the OS crashes, I guess the only thing that could happen is that something is cutting the power from the motherboard to the PSU?

    Well I've never heard of that happening...and this is a new computer too...like 2 months old. So you think a cable is loose/damaged between the motherboard + PSU?

    Most important question..

    Does this only happen at around 10:30pm?
    Do you only play your flash game at around 10:30pm?
    If no does it happen at other times?

    Could be your graphics card overheating or a virus.(If this only happens at around 10:30pm)

    Im leaning toward a virus. or someone controlling your computer and shutting things down.(ie Remote Desktop)
