  • What could possibly cause my computer to power down at random times?

    - by geoffreydv
    I have recently bought a new Power Supply and a new graphics card. My PC ran smoothly for a few months now but since a couple of days I'm having a strange problem. I am trying to isolate the problem to a specific piece of hardware (because if it's either the Power Supply or the Graphics card they are still under warranty). The problem started when I was playing a game (diablo 3). My PC suddenly powered down. I was unable to turn it on again by pressing the power button. I unplugged the power cable for a few seconds and plugged it back in. This time the pc powered on but the indication light turned orange instead of white as it normally does. The fans were not spinning and I did not see anything on my screen. After trying a couple of times I gave up. Two days later I tried again and this time the PC did boot up as usual. Everything looked okay until I tested if the problem was resolved by starting Diablo again. After about two minutes it powered down again as it did the first time. If I don't run any games my PC does power down after about 3-5 hours. Another fact that might be relevant: One time the PC did not shut down immediatly, instead first my graphics "powered down" but the music I was playing kept on playing. After about 20 seconds the pc powered down completely as usual. What I also noticed is that when I boot instantly after a power down, the chance of another power down occuring is much higher. Does anyone have an idea what could be causing this kind of behaviour or has a certain tool to diagnose the specific hardware parts? Thanks Specs: Memory: 6GB Processor: Intel i5 OS: Windows 7 64 bit The PC is a Dell Studio XPS 8100 with a replaced PSU and Graphics card: PSU: Corsair CX500 (500 watt) Graphics card: AMD Radeon 6850

  • Computer won't stay powered up

    - by Android
    I have just tried to turn my PC on this morning and it won't stay powered up. It will come on as normal for about 5 seconds, not quite long enough for the monitor to wake up. Then it will power off. After about 2 seconds it will start again, it will continue like this until I pull out the plug. Plugging it in again doesn't restart the cycle although pressing the power button does. I have tried to clear the cmos but beyond that I have no ideas. It was working perfectly when I put it in hibernate last night. NOTE: I am using a Dell Optiplex 755 UPDATE 1: I took out the motherboard battery and it almost came on then it displays the message Error loading Operating System UPDATE 2: After taking out the custom video card, it says "No hard drive present"

  • Run a script with user interaction on log out / shutdown?

    - by lumbric
    I'd like to run a script on shut down, which interrupts the logout process and and pops up a window with zenity. My target is to get autofsck working with lightdm. It seems to work with 12.04 after installing the old *.deb file, if one runs the check script manually. In order to use it, it should run automatically on log out and ask the user if she/he wants to check the disc on shutdown. There is the option session-cleanup-script in the file /etc/lightdm/lightdm.conf which seems to work, if a bash file with full path is used (I can't place the command directly there). But if I press shutdown, there is no time for a user choice. Is there any other option to solve this problem?

  • Outlook 2003 add-in - Getting COM exception on application shutdown after creating WPF window

    - by Oliver Hanappi
    Hi! I'm developing an outlook 2003 add-in. Until now I used only winforms to display one form, but today I've added a WPF window for more complex stuff. DUe to the WPF window, a COM exception is being thrown when outlook shuts down. Does anybody know why? I need to start a separate thread for the WPF window in single apartment state. Here is the exception: System.Runtime.InteropServices.InvalidComObjectException was unhandled Message="COM object that has been separated from its underlying RCW cannot be used." Source="PresentationCore" StackTrace: at System.Windows.Input.TextServicesContext.StopTransitoryExtension() at System.Windows.Input.TextServicesContext.Uninitialize(Boolean appDomainShutdown) at System.Windows.Input.TextServicesContext.TextServicesContextShutDownListener.OnShutDown(Object target) at MS.Internal.ShutDownListener.HandleShutDown(Object sender, EventArgs e) InnerException: Best Regards, Oliver Hanappi

  • Archlinux auto-start after I shutdown my computer

    - by madper
    every one. I'm in a big trouble. My computer (HP ProBook 4230s) has two OS----Archlinux and Win 7. When I use Archlinux, after halt my computer, it will start up after a while without press power. And there is an other thing. My computer's clock will be wrong. Many times I change it in bios, but it wrong again. If I turn off the computer from Win 7, it will never start up untill pressing power bottom. And the clock will be right. I also used ubuntu\debian\mageia, and both of them are fine with my notebook. Is there some configure is wrong with my ArchLinux?

  • standard way to perform a clean shutdown with Boost.Asio

    - by Timothy003
    I'm writing a cross-platform server program in C++ using Boost.Asio. Following the HTTP Server example on this page, I'd like to handle a user termination request without using implementation-specific APIs. I've initially attempted to use the standard C signal library, but have been unable to find a design pattern suitable for Asio. The Windows example's design seems to resemble the signal library closest, but there's a race condition where the console ctrl handler could be called after the server object has been destroyed. I'm trying to avoid race conditions that cause undefined behavior as specified by the C++ standard. Is there a standard (correct) way to stop the server? So far: #include <csignal> #include <functional> #include <boost/asio.hpp> using std::signal; using boost::asio::io_service; extern "C" { static void handle_signal(int); } namespace { std::function<void ()> sighandler; } void handle_signal(int) { sighandler(); } int main() { io_service s; sighandler = std::bind(&io_service::stop, &s); auto res = signal(SIGINT, &handle_signal); // race condition? SIGINT raised before I could set ignore back if (res == SIG_IGN) signal(SIGINT, SIG_IGN); res = signal(SIGTERM, &handle_signal); // race condition? SIGTERM raised before I could set ignore back if (res == SIG_IGN) signal(SIGTERM, SIG_IGN); s.run(); // reset signals signal(SIGTERM, SIG_DFL); signal(SIGINT, SIG_DFL); // is it defined whether handle_signal can still be in execution at this // point? sighandler = nullptr; }

  • Dealing with a shutdown during a file write?

    - by Ken
    All, I'm working on a Real-time system, VxWorks I think, I'm saving application settings to a file. What's the best way to handle preserving the settings if the system shuts down or loses power in the middle of a file write? All I can think of is shuffling a few files around or reducing the frequency at which i Save variables in order to reduce incidents.

  • Kernel error causing cpu to go into shutdown state

    - by EpsilonVector
    What kind of Kernel error can cause the cpu to go into a shut down state? I'm doing a homework assignment in OS, and we did changes in sched.c (adding a new scheduling policy, which involved ading another prio_array to the queue and switching between them when needed). Processes using this policy cause the cpu to enter a shut down state when they finish. Any suggestions where to look?

  • Prevent Application Shutdown iPhone

    - by Paul Alexander
    I'm building a little dialing program for my kids so that only 4 "safe" numbers are available for them to dial. I'd like to start the app, hand them the phone and have the app be the only thing running until they come back home. Is there a way to keep the application running and prevent the iPhone from shutting down the app?

  • Thread Suicide on Shutdown?

    - by yar
    I have a java.util.Timer running at a fixed interval. I have added a Runtime#addShutdownHook and it shuts down when the VM ends normally or abnormally. However, it keeps the VM alive when a main terminates, unless I insist by doing a System.exit in the main. Is there any way for me to check if I'm the last Thread standing, or some other way to avoid altering a main that would exit normally on finish? Note: I know a lot of people believe that java.util.Timer is deprecated (it's not), but unless your alternative helps me solve this problem...

  • Is it ok to Swallow SocketExceptions in some situations? (C#)

    - by NoPyGod
    Let's say I've programmed an application which connects to a server using the Socket Class (TCP). If I encounter a SocketException while reading or writing, then obviously I have to do go ahead and run a disconnection routine to change the application's state to Disconnected. But what if I've started to Disconnect, and while I'm cleaning up, a SocketException occurs? The SocketException doesn't really mean anything to me, as I was going to shutdown the socket myself anyway.. so is it ok to swallow it? I really want to know what the best practice for this situation is.

  • How to "unbind" a socket programmatically?

    - by ryan1894
    1) The socket doesn't seem to unbind from the LocalEndPoint until the process ends. 2) I have tried the solutions from the other question, and also tried waiting a minute - to no avail. 3) At the moment I have tried the below to get rid of the socket and its connections: public static void killUser(User victim) { LingerOption lo = new LingerOption(false, 0); victim.connectedSocket.SetSocketOption(SocketOptionLevel.Socket,SocketOptionName.Linger, lo); victim.connectedSocket.Shutdown(SocketShutdown.Both); victim.connectedSocket.Disconnect(true); victim.connectedSocket.Close(); clients.RemoveAt(victim.ID); } 4) After a bit of googling, I can't seem to be able to unbind a port, thus if I have a sufficient amount of connecting clients, I will eventually run out of ports to listen on.

  • OnShutdown() not working on XP

    - by Daro
    I have a service registered for shutdown events (.Net 3.5): public ServiceName() { InitializeComponent(); base.CanHandleSessionChangeEvent = true; base.CanHandlePowerEvent = true; base.CanShutdown = true; } protected override void OnShutdown() { try { if (Program.Debug2Eventlog == true) { WriteEventEntry( "Computer is shutting down.", EventLogEntryType.Information, 0, 3); } } catch {} base.OnShutdown(); } Windows 7 logs the event just fine, but XP doesn't. Am I missing something?

  • Add a Sleep Timer to Windows 7 Media Center

    - by DigitalGeekery
    Do you make it a habit of falling asleep at night while watching Windows Media Center? Today we are going to take a look at the MC7 Sleep Timer for Windows 7 Media Center. This simple little plugin allows you to schedule an automatic shutdown time in Media Center. Note: At this point MC7 Sleep Timer doesn’t work with extenders. If you’re using ClamAV or Panda it may detect this plugin as a virus, we’ve tested it and this is a false positive for these two antivirus apps. Installation and Usage Download and install MC7 Sleep Timer. (See download below) After the installation is finished, you will find MC7 Sleep Timer located in the Media Center Extras Library. Click on the tile to open the timer and configure your settings. The MC7 Sleep Timer will open in full screen mode. You can choose to shutdown the PC after 30 or 60 minutes, create a custom length shutdown timer at any 5 minute interval, or select the exact time you want the PC to shutdown.  After setting your PC to shutdown, you’ll get an audio confirmation. To set a custom timer length, scroll to the “Custom timer” option and click right or left on your Media Center remote or, the right or left arrow keys, to choose how many minutes before shutdown. To schedule a shutdown for a certain time, browse to the “Shutdown at time” button, and scroll right or left with the arrow keys on the keyboard or remote. When you’ve chosen your time, hit “Enter” on the keyboard or “OK” on the remote.   Clicking the “Monitor Off” button will turn off only the monitor and “Cancel Timer” will cancel your shutdown request. Conclusion If you often find yourself falling asleep every night watching Media Center and then fumbling and stumbling in the middle of the night to shutdown your computer, MC7 Sleep timer might just be a perfect addition to your Media Center setup.

  • Grub menu will not show the first time I try to boot my ubuntu server 12.04 after it is shutdown for a long time

    - by user211477
    I am running into a booting issue after installing Ubuntu Server 12.04 LTS. Following is the symptom of the problem. SYSTEM DESCRIPTION: Dual core AMD Athlon 64 3 Disks: two SATA (out of which one is SSD) and one PATA. Using LVM for disk partition management. /boot is not under LVM rest of the partitions are. / is on the SSD BIOS boot sequence is correct and points to the disk with /boot and boot loader is installed on this disk. SYMPTOMS: POST messages Blinking cursor on first line then moves to second line Screen flickers then becomes black Everything is unresponsive, hard reboot POST messages will not show up on screen. Monitor displays powersave message Force shutdown machine again. Shutoff power to machine for a few minutes. Restart machine. POST message show up. Grub menu shows up Ubuntu server 12.04 boots normally. From now on Ubuntu server boots normally until machine is shutdown for a long time (for example, 30 mins) Repeat steps 1 through 13 once the machine is started after a long time. WHAT DID I TRY? I read several posts and have tried: radeon.modeset=0 setting the gfxmode edd=0 nolacpi boot-repair Nothing seems to work. In my search I did see only one post with this same symptom. Unfortunately, I am not being able to locate that post anymore. The interesting fact is that with this same machine configuration, if I install Ubuntu Desktop 12.04 then everything works fine. Any help will be appreciated.

  • Is there any way to detect when nginx has completed a graceful shutdown?

    - by Daniel Vandersluis
    I have a ruby on rails application which is running on passenger and nginx, with one main webserver and multiple application servers. I am trying to update my deployment process in order to minimize (or ideally, remove) any downtime caused by the deployment. The main roadblock right now is that passenger takes some time to restart (ie. reload the application), so in order to get around this, I want to stagger my restarts so that only one app server gets restart at a time. In order to do this without losing any long running passenger processes, I am thinking I need to gracefully shutdown the app server's nginx instance, which will cause it to no longer accept new connections but continue to process the existing ones; as well, HAProxy will detect that the app server is down and route new requests to the other server. However, assuming that there is a long-running process, I am not sure how to detect when the graceful shutdown has completed so that I can start it back up. Since the shutdown is caused by sending a signal (ie. kill -QUIT $( cat /var/run/nginx.pid )), and the kill command will return immediately, I cannot combine commands (ie. kill ... && touch restarted), as the touch command will execute immediately, even if nginx hasn't completed its shutdown. Is there any good way to do this?

  • Windows7: Howto force a "do you really want to shutdown?" dialog

    - by Vokuhila-Oliba
    Sometimes I wanted to choose "logout current user", but then I hit "Shutdown" by accident. Nearly everywhere else Windows7 is asking "do you really want to do this Yes/No". But that's not the case when I hit the "Shutdown" button. Windows7 shuts down immediately without giving me the chance to correct my mistake. Q1: So I am wondering why Windows7 shuts down immediately without asking "really do that?" in this case. Q2: Is there a way to change this behavior? E.g. Could I force Windows7 to display a dialog asking "Do you really want to shutdown ?". ADDED: I am running Windows7 Professional 64bit. ADDED: I tried to change this behavior with the policy editor. It seems to be very easy to completely remove the Shutdown button from the start menu. But I couldn't find an entry to turn on such a Yes/No dialog.

  • I need a relatively cheap host, which will be able to handle sudden peaks in traffic?

    - by Morten K
    Hello, We're launching a product in a few months, which will obviously have a website. Judging from our current traffic, we believe that overall traffic will probably not be that much, but we are aiming at promoting the site heavily using social media. This has the typical problem, that IF we get suddenly get picked up by a large tech blog, we will see a sudden burst: A very heavy increase in traffic all of the sudden. If we use a cheap charlie host as our current host is (www.unoeuro.com) or something similar like GoDaddy, I'm afraid that the site will go down under the load. If that happens, then we might as well have thrown our social media marketing dollars out of the window. Our site will be relatively lightweight, all videos hosted at Youtube or Vimeo and other than that mainly just a standard webpage (ie nothing too heavy). I am hoping for recommendations for a good hosting company, which has some form of scalable hosting, so if / when a traffic surge hits, the site will not go down.
