    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'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 I am guessing it's not that.

    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'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.
    IE7 is nine years behind the standards or wrong.
    But it works in IE!

    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 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..

    Nope, actually just playing a flash game.

    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 2 months old. So you think a cable is loose/damaged between the motherboard + PSU?

  15. #15
    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)

    Does this only happen at around 10:30pm? No, happens randomly now.
    Do you only play your flash game at around 10:30pm? No, that was only the most recent time.
    If no does it happen at other times? Just randomly surfing the web, doing nothing critical.

    It's probably not remote might be a virus, but I scanned once and nothing showed up.

    I would guess malware - possibly a trojan. Someone remotely can easily shutdown your pc with the click of a button. They may also have installed a scheduler to shutdown your computer when they are not connected to your pc.

    I am good at checking HijackThis logs if you want to post one. You could download from:

    You may also wish to try a different anti-virus scan - Personally I think that has the best detection rate. They have an online scan you could try. It doesn't fix the problems found (The online scan), but will let you know if there are any, and which if any malware you have. Again, I would be happy to check your hijackthis log if you wish to post one.

    Your best bet is to get hold of a copy of sysinternals tcpview.exe, look for weird applications that are connecting out, etc. As others have said it is likely some form of virus.

    It may be a virus issue. You can check the log of HijackThis as zwolf told.

    There's a program called Anti-Porn I installed on my cousins computer that does all these things to prevent him from breaking it again. It's hidden from program files folder even when hidden folders are turned on. Its not in processes and not in any toolbars. Maybe your parents/wife/husband secretly installed it?
