“(Not Responding)” – What does it mean, and what do I do about it?

'(Not Responding)' is Windows' way of telling you that a program might have a problem. Sometimes '(Not Responding)' is benign, but sometimes it's a sign of a deeper issue.

//

I am using windows XP PRO, and I am having difficulty when I am browsing or using a program. After a few minutes the computer freezes and I get a message in parenthesis saying (not responding). Sometimes I have to log off and log-on again to fix this problem. But after a few minutes it happens again. How can I fix this?

“Not Responding” appears in the title bar of a running program when Windows detects that the program isn’t behaving properly. Exactly why depends on the specific program and what you were doing at the time.

Let’s look at some of the possibilities which range from actual software or hardware problems, to user impatience.

Windows expects a running program to “interact” with Windows, and respond to Windows’ requests in a timely fashion. If you type a key and the application doesn’t take it because it’s too busy doing something else, that could be a problem. Similarly, if you click on the Close Program “X” on a programs’s window, and the program doesn’t acknowledge that, then that too is a potential problem.

When Windows asks a program to do something, like take a keystroke or close itself, and the program fails to acknowledge that request within a certain amount of time, the program is “Not Responding”. If the program never comes out of that state, we might also call it “hung”, as in “hung up” on something.

There are “legitimate” reasons this can happen. For example, if the program you’re using is doing some very long, CPU-intensive calculation, it might not respond in a timely fashion. An example might be a graphics program performing a reduction or other operation on a large image. If, during that operation, you attempt to close the window and nothing happens, after a few seconds Windows might add “(Not Responding)” to the title bar to indicate that it has tried to pass your request to the application, but the app’s not listening.

Anything that causes the application to stop responding can cause Windows to add the ‘(Not Responding)’ moniker to the title bar.

While it might be considered bad form or bad design to not respond to user input or to Windows while performing lengthy calculations, it’s quite legal and legitimate. Once the calculation is complete, the program starts listening and responding again.

A recent real-life example of my own: earlier this evening I was working on a Visual Basic program that performs various database operations. I modified it to access a database remotely across the internet which turned out to be a mistake, because the operation became extremely slow on my DSL connection. While VB was accessing the database, it was unresponsive to everything else. Windows tagged it as “(Not Responding)”. Since I hadn’t saved my program to disk (bad form on my part), I was loath to just kill it and lose my most recent edits. So I just let it continue while I did other things. An hour later the operation completed, and VB became responsive again.

Anything that causes the application to stop responding can cause Windows to add the “(Not Responding)” moniker to the title bar.

So while lengthy calculations are one semi-legitimate way it could happen for a while, what are some of the other things that can cause it?

  • Programming Error – the classic case of an “infinite loop” in programming is perhaps the most common example – if an algorithm is mistakenly written such that it never ends, and within that algorithm Windows is never given a chance to operate, the application may become “hung” and unresponsive. As a user of the app, there’s not much you can do here except avoid whatever it is you did that brought the application to that point.
  • Software Design Error – really just a variant of the preceding point, but I think of it as a different class of problem. The example I see from time to time is a program that displays an error message in a pop-up box. Some applications transfer total control to that message box such that the application’s main window will stop responding until you click “OK” on that message. If for some reason that box is displayed improperly – say off the screen, or behind the application’s main window – then it will appear as if the application is hung as it waits for you to click on the message you can’t see.
  • Hardware – hardware that is malfunctioning can, in some cases, cause the software that interacts with it to fail in ways that make it unresponsive. For example a USB card reader might experience a failure, and the next program to attempt to read from the device might end up “(Not Responding)” because of the problem.
  • Hardware Drivers – This is really just a combination of the previous points. All the hardware on your system is in some way controlled by software. If that software has a bug, even if the hardware is working properly, the result could be a hung application. If hangs appear to be related to interacting with a specific device it might make sense to make sure that you have the latest drivers for that device – not to mention the latest updates for Windows as well.

Viruses and Spyware – whether intentional or simply because they’re poorly written, viruses and spyware can in fact cause other programs or Windows as a whole to misbehave in various ways including causing applications to become unresponsive. Make sure your anti-virus and anti-spyware software is running and up to date.

All that is pretty vague, I know. It almost boils down to “it could be anything”, which is unfortunately fairly accurate. The actual cause, and the solution, will depend on the specifics of what you’re seeing. Does it happen all the time, or only when you do certain things? One specific application, or several? All of these things and possibly more are clues necessary to ferret out the cause and come to a solution.

Without more specifics, my general recommendation is to make sure Windows is up to date, make sure your hardware drivers are up to date, make sure that the anti-virus and anti-spyware packages on your system are working and have up to date databases. If the problems persist, try to narrow down the common causes,
if any.

    hi leo. i am using IE7 beta3 with xp sp2. when browsing this happens often. i should probably tell you that have cable internet access. microsoft said it is a data transmission error (that the pages are loading incompletely) and that is why i can’t click on the page and i have to use the task manager to close the browser. IE provider says it’s IE7’s beta version. I’m just learning this stuff but is it possible that this is a RAM issue. our total is 512. we have autocad, illustrator cs2, and flash pro to name a few.your help would be appreciated. thanks

    Hi Leo,

    I have a VB code in which I make the execution sleep for 60 seconds using the sleep method in Kernel32.dll
    The trouble is the task manager the program application is listed and shows that its ‘not responding’. Although the intended operation of updating my oracle database every 60 seconds is being performed as desired.
    Why is it showing not responding in the task manager?

    Regards,
    Mani

    Because for those 60 seconds your application isn’t responding.

    Try putting a 1 second delay in a loop of 60 iterations. The performance impact
    will be negligible and Windows should be happier.

    Hi.

    Firstly, let me thank you, for your reply.

    I followed your suggestion, but, as long as the program is in the 60 iteration for..loop, the application shows not responding in the task manager.
    I noticed one thing though, as soon as the program comes out of the loop the program returns to running state in the task manager.

    Is there any other workaround?

    Mani

    We have a VB Application which is running on win 2003(Application Server) and SQL 2005(cluster DB), to handle the performance we run around 4 instance of the same VB application on the same Application server. When we run more than 2 instances of the application (around 4), these few of the instances are going to NOT RESPONDING stage for a while and coming back to normal, this is happening for all the instances randomnly. But the CPU utilization is less than 10% and the server is normal and responding, only Apps are going to Not Responding stage.

    We have recently migrated these apps from Win 2000 and SQL 2000 to new server with Win 2003 and SQL 2005 from then we are observing this issue.

    Please help me if you have any solution for this.

    Dear Leo,

    I usually log in to my Bebo account about twice a day. I enter the site http://www.bebo.com/ into my browser/address bar, and the main page always comes up with the space to enter your username and password.

    I would usually type in my username and password and my home page would appear with the ch-ch-changes and all that jazz, but today when I entered my details and pressed enter to sign in, only the header of my Bebo home page loaded and then the program came up with “(Not Responding)”. It has never done this before and I have no idea why. I had to close the window and reopen my browser again. I wondered if Bebo was under maintinance for the time or something, so I typed in one of my friends username and password (still using the same computer) and it took me to her home page no problem. Why is my Bebo page not working all of a sudden? Please help me! By the way, all my other internet programs/websites I visit are working absolutely fine, it’s just my Bebo home page with the problem.

    Regards,
    Kim.

    Hi Leo,
    I read your text on the ‘not responding’ state of windows XP. I write some small applications myself (delphi) and when these applications have some bigger tasks to do, windows also consider them as “not responding”. I built in some progress reports in my applications (10% complete, 20% etc) and when windows decides that my program is “not responding” these progress reports no longer are updated. my question is. with these longer tasks, is there a way to still remain responding according to windows ?

    Leo,

    Your article is interesting and helps me understand what might be happening, I wonder if you have missed some other scenario. Many applications are multi-threaded, and as such perform most of their long running or CPU intensive work in a thread that does not interact with the UI. In applications like this, there should be no ‘Not Responding’ scenarios. However, I do see applications that this occur even though they are multi-threaded. Is there any way that the OS is actually causing the application to not respond to the OS’s request to the application?

    In your example, you wrote the application so it was easy to determine the problem. Is there a way to determine what an unresponsive application is doing? In your case, it was network I/O, this would have caused your application to block on the OS’s low level I/O.

    Thanks for any thoughts..

    I’ve actually never found a reliable way for non-programmers to answer “what is
    this application waiting for” when it hangs. The developer, of course, can run
    the application in a debugger and often see exactly what;s going on, but those
    resources are not available to the average user.

    Naturally multiple threads need to interact. Typically if a UI thread hangs
    even though there’s another worker thread doing the heavy lifting, it’s because
    the UI thread is in fact waiting for something from that worker thread, or
    there’s a syncronization problem between the two. (OR there’s something in the
    UI that needs waiting for.)

    Thanks,

    I have ‘one’ program, Incredimail, that is non responding. I have done a system restore, uninstalled and reinstalled the program, all with the same results. The home screen comes up but the cursor does nothing when I click on a task to do. The Incredimail support people have been making suggestions but nothing useful. All of my emails and address book is tied up. No other programs are running except Windows so I don’t think it is a math delay. Any suggestions? I know when I uninstall not everything is deleted so when I reinstall I get the same results.

    I’m developing in Access 2003, and I use a lot of VBA. I have a CPU intensive process that invariably results in a “not responding” message in Task Manager. Once that happens, my progress counters also free. If I leave it alone, it finishes on schedule. Is there something like “doevents” for Access 2003? I sure would like to be able to run my application in the background, pop in from time to time to monitor its progress, and avoid the “not responding” message. Ideas?

    I’m not a PC expert, but I’m quite certain that one aspect of this problem is the speed of your broadband connection. I had a very poor download speed with one provider, and switched to BT, paying for its premium broadband service. Now I’ve got it, 20% of all the links I click on, result in ‘this program is not responding’ etc – ie an entirely sudden, new problem I never had before, and without any other changes taking place (eg software, firewall etc). So I do wonder whether my PC is now just trying too hard and too fast for its own good!!?. One thing’s for sure: it ain’t solved easily, because even BT’s own experts can’t tell me whats wrong, and how it might be put right….

    I have a chronic and severe case of DO NOT RESPONDing. It seems to have grown when I unwittingly acquired COMPUSERVE, which I did not elect to have, but that seemingly has pirated my system. This happened when I subscribed to Norton Antivirus and was required to remove all antivirus programs so they could download the Norton. I was told that the download would take about 45 minutes, the sytem would turn off, and when I restarted it I would have Norton operational. However, when I turned on my system, it had been taken over by COMPUSERVE and there was no Norton–which basically told me that if I did not send them “only $19.95 a month” they would crash my system. I called the Norton tech and they spent hours, and were able to download the Norton and get most of the COMPUSERVE off my system, but it is still festering in a folder on my desk top, that also contains all of the files on my system. I cannot delete it. When I try to drag the files to the TRASH, I get a message that says “YOU CAN NOT DELETE THIS FILE.” Since then, everything I do is very slow and if I have even two files open, it (does not respond). ALSO I can not RESTORE my system to a date before it was eaten by COMPUSERVE, as they also disabled my restore application and it does not work after the date of seizure. ANYBODY know about this and does anyone have any SOLUTIONS to rid myself of COMPUSERVE?????????????? THANKS S

    I’m thinking that things sound bad enough that you may be looking at a reinstall of your system to clear this thing up.

    Jacqui Faulkner posted here at June 29, 2008 9:51 AM and mentioned her own solution to ‘Not Responding’ messages.
    I sure can relate to the frustration these messages and the delays in processing Windows commands can cause.
    I run McAfee Security and McAfee SiteAdvisor is an automatic installation component which sits on the bottom of your screen above the Task Bar.
    So, I have discovered that by clicking the little arrow next to the McAfee SiteAdvisor icon a drop down menu appears and there is the Disable McAfee SiteAdvisor option.
    I have done that and will report back here in one week and let you know the outcome.
    PS I will surely know if this makes a difference as I would average 10 or more ‘Not Responding’ messages per day.

    I have the same problem and now cannot access anything on the computer. In looking for a fix I discovered that this is an ongoing problem since approx. 2004 on tens of thousands of computers, maybe hundreds of thousands, maybe millions, who knows. This is unbelievable. I cannot believe anyone including microsoft has not been able to or willing to fix this problem. If anyone has a fix he/she could probably make a couple million dollars.

    The issue here is that it’s not one problem. “Not Responding” is a symptom that can be caused by any of thousands of different types of problems. As a result it’s not possible to come up with a single fix for this symptom. Each problem must be fixed individually.

    I’m getting this more and more…not responding…hanging apps…locking up. Never had any problems with connection with Comcast, but I was a fool and decided to go with Verizon FiOS. I am NOT happy….and support there is horrible. My virus, adware, spyware programs are all current and up to date. Computer is 1 and 1/2 yrs old. I’d throw it out and go back to Snail Mail, but they’re closing post offices. Yada yada yada.

    Let me correct what I wrote:
    I too, have that “program not responding” error when clicking on MS Word and MS Excel document and worksheet files and when shutting down the computer. I tried going into windows task manager and ending explorer and then running it again. This seems to fix the problem but only temporarily. After awhile it resumes again.

    I have been running antivirus and antispyware programs. The computer appears to be clean.

    Please make some suggestions.

    I have “RegCure” installed on my computer but I still keep getting the Message “Not Responding” I scan with regcure but its an on going thing.
    Can You Help…….Please?

    Not at all surprised that a registry program would have no effect. This type of problem is rarely registry related. It is, however, related to the SPECIFIC program that’s not responding. There is no single, general, fix.

    Hi,

    I’m getting this problem too. It seems that whenever I open a bunch of programs (sibelius, orian platinum) I can’t do anything in them, because the second I open them it says they aren’t responding. I get the same thing with explorer too, although its less frequent.

    My computer is also running painfully and ridiculously slow…

    As far as I know, my norton is up to date, and I’m pretty sure I have spyware stuff too, though I don’t really know… (I didn’t set this computer up myself)

    My real question is weather I need to take this in to a place and get it looked at or not

    Thanks!

    I’ve noticed this problem on EVERY computer that I access and it seems to have become a fairly common problem with everyone. My personal opinion is that our computers are being internally bogged down by tracking software. these Not Responding problems began soon after the Patriot Act was passed. Prior to which when you requested a page, your browser would not freeze and you could click another link prior to the first requested one loading. Now as soon as you request a page it is almost as if the internal tracking is so aggresive that it boggs the entire computer down. may sound like a paranoid delusion but I notice these small changes and it is apparent that we are being cataloged and tracked in everything we do on the web. So much that it is making our computers non responsive. That’s my take.

    I have gone through several situations with my previously used computer.I think I have eradicated most of the other users stuff,perhaps one or two are hiding in here somewhere.But since I have been using computers since June I could be lost in space anyway.It all started as registery errors,then plain old errors,stops, slow downs,dissconnects,transfers,deletions,doing something totaly different now to not responding,total stops,deletions,transfers-like posessed.I got Reg Tool and Norton,Reg Tool-does more,every day I get 5-10 reg probs,1000 of these and 1000 of those to fix.I think I may have hit the end of these problems? Is this the way it goes on the internet? I hate “not responding” I cant seem to get rid of it.

    wenevr i open my lap tp it says the window is not responding? what should i do? what is the problem behind it? can i get any remedy?

  76. tonygts Reply

    Yes Leo, I totally agreed with you that Not Responding message in title bar is quite legal and legitimate while Windows (especially Vista) is performing lenhthy operation. However, it is indeed an overlook of Miscrosoft in designing an OS (especially a new OS like Vista and Windows 7) without thoroughly consider assigning high enough proirity interrupts to Input/Output devices such as mouse click and keyboard input.

    I have been facing the same “Not Responding” problem with Vista for about a year, and still couldn’t find any solution after so many complaints at many forum sites; e.g. http://forums.cnet.com/5208-12546_102-0.html?threadID=302723&start=30&tag=forum-w;forums06

    This problem seems very likely to be Vista problem and not the broswer (IE) problem because it also happens to other application like Microsoft Excel especially when Excel is accessing the Internet to retrieve data using WebQuery. If I click a second time on any open program, I get that “Not Responding” error message almost imediately and I have to wait about 10 to 15 seconds. This is not just very frequent, but a sure occurence. It is not a Ram problem either because I have a 3G Ram in my laptop. Very frustrating indeed!
    I kind of agree with someone in a forum saying that it is a problem of Agreesiveness or Too Sensitive (timeout too fast) to this “Not Responding Issue” in Vista though Microsoft may think that it is legimate, which I think is a “Frustrating Legitimacy”! Just wonder why Microsoft is not trying hard enough to resolve this problem after so many complaints in such a long time!

    I am getting “not responding” om various programs more-and-more these days on my XP Pro computer. I am familiar with IBM mainframe operating systems, so I know something about the internals of operating systems. My interpretation of the problem is that there is a resource shortage within the operating system, but I have no idea what is short nor how to correct it. When this happens I usually see two lines for the affected application in the Task Manager Applications Tab.
    I cannot put the blame on any one application, as many applications go into this state now-and-then (Firefox, Ad-Aware, Spybot Search and Destroy, et alii). I would have expected Vista or Win7 to behave more sanely, but from some of the comments I read, it appears that the problem still exists in the newer MS operating systems.

    This problem happens continually under Windows 7 and it is obviously NOT an application problem. It happens in IE8, in WordPerfect, and with other software programs. Something as simple as trying to rename a folder hangs up consistently. I’ve checked for a eliminated all spyware and viruses. I’ve tried re-loading the applications. And it still occurs. Once again, it appears that Microsoft is using all of us as their beta test sites for software that ought to have been working before releasing it at hundreds of dollars per copy. I’m really frustrated with this.

  79. Debbie Okubo Reply

    I also get “not responding” every 3 minutes and takes between 15-30 seconds to come back. It happens when I’m on different websites, so it’s not related just to 1. It’s happened on MSN, bettycrocker & facebook. I use Vista and have 3G RAM. It started about 2 months ago. It is very frustrating. What should only take a couple of minutes to look up can take an hour or more since you have to stop & wait every 3 minutes.

    Using laptop with Vista Home Premium, Core2Duo, T5750, 2Ghz & 3GB RAM. I am also getting the same Not Responding error. It is ANY application I run. All Office Apps, Firefox, you name it…it’s happening…and it also started about 2 months ago!!! How odd… Just guessing it is a Microsoft licensing issue with a 3rd party product that expired & stopped working on a most recent Windows Update. Or it could just be plain broken – Ockham’s Razor would suggest the latter!

  81. roddog Reply

    I too had Vista start doing this about 2-3 months ago. I was running Windows 7 beta on another machine and it was perfect. I, in my cynicism, assumed it Msoft’s way of forcing an upgrade to 7. So, I dutifully did so on my one year old Vista box. To my dismay programs hang constantly in in 7, heck it even hangs in shut down. All this from a clean install. All drivers are updated and no hardware was incompatible. The part that stinks the worst is that the machine has a intel matrix storage raid, since its software controlled every time 7 has to be shut down by the power button method the 2 terabyte drives have to be verified for errors…say goodbye to 5-6 hours of computing time as it slows the machine to a crawl.

    I truly am considering drinking the Mac Kool-Aid and getting one and saying it just works…and when it doesn’t a “Mac Genius” will fix it.

    Same happens to me. Mostly in Windows mail and IE8. I am operating on vista home premium 32bit with 4 gis ram. I have checked the system with Norton IES 2010, Maleware byte and Advanced system optimizer 3. No malware found. I am curious to know how to find out what is running that slows the interaction between windows and the application. In my case it is the Microsoft’s own windows mail and IE8.

  84. James Reply

    I think it is a bad design for microsoft to allow a third party program to take over the OS with this “not responding” and in vista and windows 7, the little circle…. The operator is allowed to be impatient and should have the ability to “kill” the “not responding” task. But very often, I find that the only solution is to reboot the machine with a power switch. This should NEVER happen. The OS MUST exercise control over all tasks. Microsoft has taken a very poor design approach at this IMHO.

    This is happening to me when working with Microsoft office. Say.. I am inserting a picture. Yikes.. stalls then I have to wait, stalls, wait. Am I short on RAM… I have two gigs right now. Maybe I’ve got too much in my system tray? I never had these issues with my old computer which had less memory and I ran the exact same programs.

    I too have the “not responding” curse and if I let the computer just set, it corrects itself after a few minutes. The interesting factor is that I have 2 computers. both on a cable connection, and it seems to occur more often on one than the other. I swapped the 2 machines and it happened again…more on the swapped one than the other. Ever heard on an internet connection being the culprit?

    Hello Leo
    I can see by the comments that tons of folk are having the not responding prob on XP, but from what i can see is that we still do not know what to do about it. so, short of reinstalling windows, what do i do about it? can you tell me?

    thanx chilly

    As you’ll see in the article you just commented on, “it could be anything”, so there’s no advice that I can give here that will simply answer “what to do about it”. It depends on all of the specifics of your situation. Reread the article and perhaps you’ll have some ideas of where to look in your situation, but this is a case where there’s little specific “how to fix” advice I can offer.
