What is using cycles CPU on my computer?

• Demon NTP using a lot of cycles CPU

  My MacBook Pro (early 2011) running OS 10.11.4 fonctionnee hot and slow recently.  I turned on Activity Monitor and ntpd (the demon of time network) is constantly to consume 12 to 15% of cycles CPU.  I found an article on the stack Exchange, who said that if you see activity like this on your NTP daemon, it could be a sign that someone used a DRDoS attack.  They suggested defining the demon NTP to refuse incoming network connections - which I do not know how to do.  (I'm on Mac OS firewall).

  I took a sample of activities ntpd.  It's a little hyperactive beast.  The ratio is about 2 ½ pages long during only a short excerpt.  I can paste the report into this thread if it helps.

  But my real question is: is it normal that ntpd to be so active?  If this sounds abnormal, how can I get the little beast under control?

  In case it will help, here is the report of the sample of activity that the activity monitor took of ntpd.  Of course, it seems that he is busy, if all this has to do is sync with a network time service.

• MacBook Pro random high utilization of the processor (iCoreService/DCAManager using + 400% CPU?)

  Hello

  I'm running an Early 2011 Macbook Pro running OS X Yosemite 10.10.5 with a 2.2 GHZ Quad Core i7 processor 1 TB Samsung 840 EVO SSD and 16 GB of RAM Crucial. I noticed for about a month, I'm going to do a simple task or two on my Mac, then all of a sudden I noticed spikes CPU temporary, 90 + degrees C and the kick of fans trying to cool high speed. Well, I don't know why this is happening when I do nothing to justify a high utilization of the processor. I'm used to the CPU running hot when I do something intensive graphic as running Autodesk Inventor CAD software, run a machine virtual or even watch a 1080 p @ 60 fps video on youtube (it is the lowest resolution that requires the Mac switch to the dedicated AMD Radeon 6750 M GPU that usually eventually warm it quickly) , but this use high random that happens when I have Mail open in the background, and one tab open with a 720 p @ 30 fps video Youtube open (or even less). I took a few screenshots of the activity Manager indicating the best processes and Intel Power Gadget indicating the temperature of the CPU:

  

  

  

  Does anyone know what are iCoreService and/or DCAManager and why they use so much of my CPU when this happens? And someone has encountered this weird behavior before? Thanks in advance!

  The most likely cause is an applicztion you have running that is corrupt and forcing them to use the CPU too. Were you able to kill the process in activity monitor? If you have not yet tried to do, so I'll try that first. I would also try to quit all open applications.

  If you start the computer in Safe Mode , you can test if the problem is still there. If it isn't, usually means something that is managed by you start-up or an application that you use may be the cause.

• Satellite M30x-165 - rundll 32 exe using 99% CPU

  tasks manager told me that rundll 32 exe using 99% of my CPU. (The computer is a M30 X 165) What does that mean? What I have to change that and how do I do this?
  Thanks for your help.
  Anurakta

  Hi Anurakta,

  Rundll32.exe is a Windows system file, but it can also be associated with the Whisper B virus.

  I expect not to be almost all of your central unit using this way. I suggest that you run a full scan on your system.

  Kind regards

• SVCHOST. EXE using 100% CPU

  I have a Pentium (R) 4 CUP 2.4 GHz running Windows XP Home Service Pack 3 5.1.

  In the last month, I updated my virus software - ZoneAlarm - and downloaded Google Earth.   Meanwhile, there was also many windows updates automatic including IE8.   Since the download of the update to ZoneAlarm I have the BSOD a few times (the BSOD said ' corrupted driver MMMPOOL or similar) but after reboot it was fine.

  We had a few fluctuations in power a couple of days but the computer is connected to the battery of emergency relief so has been closed properly.   When the power was restored properly the computer started and the BSOD came once again.  You had to reboot a few times in safe mode, and then selecting the option "last settings that worked.  Since then, every restart was fine (no BSOD).

  I ran a full scan, update ZoneAlarm for updates.   It is a Trojan horse that he deleted on reboot.  However, everything was very slow and firefox who previously worked very well kept freezing.  Outlook Express has been extremely slow.   IE8 was still slower than firefox.   I've updated to the latest version of Firefox, but no improvement, or worse!

  The Task Manager showed the CPU usage to 100%.

  Then I ran a CHKDSK and defrag because it had not been for some time.

  After that, the CPU usage is 100% yet once (I dunno what I used to take me to check this again.)  A SVCHOST. EXE program was the culprit to 99.   I finished the program and it came with a warning message indicating the process server Launcher DCOM had been canceled and the system has been restarted.   The PID of this program was 868.

  After a reboot, it seemed better.  I used Outlook Express OK, but as soon as I launched a browser, the CPU usage went straight to 100%.   Even if I close the browser, he remained at 100% and has remained there since.

  Online access is practically impossible on this computer, I use another computer to get help!

  Advice would be welcome.    Please note that I'm not terribly computer advice should be simple and basic English.  TIA.

  Remove the Trojan from your computer, it is stiil in your computer.
  Your computer will work normally.
  Your alarm zone anti virus program or fire wall only? or both?
  If you analyze the pc and the answer no viruses not detected.
  I swuggest you use another antivirus program by stopping zoenalarm temperory or delete, in mind that 2 anti programs antivirus at the same time on the pc will be a conflict, so you should disabel or one of them or remove.
   
  1. right click on the my computer icon go to System Restore then put a tik on judgment system for all stations restore, apply, then ok.
  2. complete the system scan and remove Trojan horse if you can find or put a carentien if you don't know what to do.
  3. restart the computer and see if it works properly and also run full system scan new .If it is clean your pc is now 100% clean of the Trojan horse.
  4 after 1 or 2 days also scan your computer and then repeat step no.1 again by going to the system restore and yesterday to cancel the tik put you on the restoration of the system shutdown for all stations, apply, then ok.

  Good luck

• Explorer.exe using 50% CPU

  My Vista has suddenly become almost unusable.  Task Manager shows explorer.exe uses 50% of the CPU.  I rebooted a couple of times.  If I use the Task Manager to kill him I can run programs using the application tab.  The computer works well without exploring. But then I don't have a task bar so I hope it's temporary.  I ran the windows malicioussoftwqare removeal tool - who found nothing.  The program is c:\windows\explorer.exe.

  Does anyone know the solution?

  Many times when someone experiences this problem, it may be due to add-ons explore or shell extensions. Consider using Sysinternals Autoruns or ShellExView. Disable Add-ons and non Microsoft shell extensions and verify the behavior.  If he went, reactivate the disabled extensions/add-ons, one at a time and see if you can identify who may be liable.

  Try a clean boot, or boot into safe mode.  The behavior persists?

  You can use Process Explorer from Sysinternals to check the stack of the thread using the most CPU in the explorer.exe process, when you experience the behavior.  When Explorer uses the CPU as you have indicated, double-click the process in Process Explorer and go to the tab of the Threads.  Sort the list of threads by Cycles Delta (descending) and note the thread at the top. Double-click it and discovered its stack. Look for third-party modules (extensions of shell or modules, AV software, etc.) in the stack.  Disable (Autoruns or ShellExView, maybe) / uninstall these components, reboot and see if the behavior is affected.

• HP mini5102 interruption using high CPU after sleep / resume

  I have the same problem described recently (without solution) on the Forum of Support HP Business. After resume from sleep, 5102 HPmini consumes constantly about 30% of the capacity of the CPU even with the system at idle. Sunny (0-3% CPU use at idle) before going to sleep. As Roderick Laird (copied below) I've already got rid of wireless assistant that caused a different problem of high CPU usage (100% CPU use even before you sleep / resume, now fixed by an update of the version unless served for those who want to keep the wireless assistant).

  Consumption of futile processor by 30% after standby/sleep is due to material interruptions (revealed by Sysinternals Process Explorer). I understand that may be due to problems such as several drivers attempting to control a device (for example, after a faulty update). But I have no idea how find the offending device or drivers.

  My guess is that many owners of this model simply did not notice the problem and they areassuming the poor performance is due to the atom processor netbook. You must use Task Manager or performance monitor to view CPU usage high, and process Explorer to find it hardware interrupts.

  If anyone has found the cause / solution?

  HP, help to resolve this issue please--nobody wants netbooks HP fall into the category "do not buy" due to persistent problems with the futile CPU usage. The HP mini 5102 is the flagship model!

  Ref:

  "Author subject: HP mini5102 interruption high CPU usage after standby Roderick Laird 24 March 2010 04:03:03 GMT - I see of other HP5102 users having problems with high use of the processor of the Wireless Wizard operation amok; I avoided this by disabling the corresponding services. But one problem remains. The system works beautifully/effectively from a cold start. However, if I go back I think that interruptions are consumes about 35% of the cycles CPU. Not something that I want to pass battery on. I made sure that all the drivers are the latest versions according to the HP support site. I also tried disabling the obvious drivers that might be wrong (wireless, ethernet, audio, non-touchpad mouse)... »

  Update the Intel AHCI 9.6.4.1002 driver (iastor.sys) removes the futile CPU usage after sleep from 30% to 20%. This is not in the drivers of HP, but is available at Intel. Subsequently the chipset driver updates might solve the problem. In the meantime:

  Disabling in BIOS Drivelock completely eliminates the problem!

  Apparently users who want a computer that is useful after sleep / summary to know somehow ignore the advice of stern of HP in the BIOS that Drivelock is recommended for safety.

  It cost a lot of time to resolve, with no whatesover help to be published by HP. My consolation is that by systematically eliminating all the bloatware and other services-waste of unused resources, pilots and scheduled tasks automatically loaded on the system (while trying to find the cause of the CPU / interrupt use) I now have a mini 5102 (SSD) that:

  * Cold boots Win 7 Pro 32 in less than 30 seconds (including wireless access)

  * Stops in less than 8 seconds

  * Beds / back in 1-2 seconds

  * Consumes less than 600 MB of RAM at idle

• Touchpad causing excessive use of CPU on Vostro 3558 (Windows 10)

  Hello.

  I am therefore unable to use Windows 10 because using the touchpad causes the process "System and compressed memory" to use more than 30% of CPU.

  I made a GIF showing what I mean:

  As soon as I start to scroll and move the pointer this process ("Sistema y memoria compartida" in Spanish, but it's the same, ntoskrnl.exe) raises my CPU usage, as you can see.

  I tried a lot of things, but I always have to go back to Windows 7 or Windows 8.

  -J' uses latest Touchpad drivers from the site Web of Vostro 3558.

  -J' tried 19.0.9.4 old synaptic drivers for Vostro 3558 by www.dell.com/.../DriversDetails

  -J' lastest synaptics.com generic drivers, tried both SMBus and IC2 versions, but they do not work at all (I even manually installed them in Device Manager).

  -This has happened the upgrade of Windows 8 to 10 of Windows and installs also in fresh Win10.

  Without drivers from dell (using default microsoft HID Driver and synaptics.com), I get no problems of use of CPU, but none of the gestures of course.

  I ask for help because I don't want to stay in Win7/Win8, and it drives me crazy.

  I fixed it messing with Vostro 3559 touchpad driver and driver Lenovo Yoga 3 1370.

  IN FACT, WINDOWS 8.1 HAS THE SAME PROBLEM, I HAVE NOT TRIED WINDOWS 10.

  THE STEPS I DID TO FIX IN WINDOWS 8.1;

  1. install the VOSTRO 3559 Windows 7 touchpad drivers:

  

  2. open Device Manager, open the section "Mice and other pointing devices" and right click on "Dell Touchpad" (it should be named only after having installed the drivers Vostro 3559). Select "Update driver software".

  3. click on "Let Me pick from a list of drivers on my computer"

  4. uncheck the "Show compatible hardware", go to "Synaptics" and select "Touchpad"

  

  5. now if you check your device manager there is NO HIGH CPU USE, BUT TOUCHPAD IS LAG like *, as on some XPS models.

  Now, why I did everything above? Because I can not install directly Lenovo Touchpad drivers without installing the first software of Vostro 3559. Synaptics software simply does not therefore not gestures.

  6. DOWNLOAD AND INSTALL THE WINDOWS 8.1 LENOVO YOGA TOUCHPAD DRIVERS 3

  

  Direct link:

  7. OPEN the DEVICE MANAGER AGAIN AND THE SAME THING, BUT THIS TIME WE will USE "LENOVO POINTING DEVICE" rather than "TOUCHPAD" OR "DELL TOUCHPAD"

  8. YOU're not in MEASUREMENT OF CLICK NOW AS a RESULT OF SWITCHING THE DRIVER, so YOU WILL NEED AN EXTERNAL MOUSE, OPEN TASK MANAGER AND CLOSE ALL SYNAPTICS and PROCESS RELATED of TOUCHPAD.

  9. GO TO C:\Program Files\Synaptics\SynTP AND OPEN SYNTPENH. EXE

  
  

  10. HERE, YOU HAVE A JOB ENTIRELY TOUCHPAD WITHOUT MAKING YOUR CRAZY CPU

  You don't need to do anything at the next start of Windows, it is already fixed.

  REFERENCE DELL FIX YOUR DRIVERS.

• Svchost.exe * 32 using 100% cpu usage

  Hello

  You did changes to the computer before the show?

  Svchost.exe (Service, or SvcHost host) is a system process that hosts several Windows services. It is essential in the implementation of the process of the so-called service shared, where a number of services can share a process in order to reduce the consumption of resources.

  Sometimes viruses can usurp themselves as system files.

   

  Method 1: Put the computer to boot and see if that helps:

  A clean boot to check if startup item or services to third-party application is causing this issue.

  Reference: How to solve a problem by performing a clean boot in Windows Vista or Windows 7:

  http://support.Microsoft.com/kb/929135

  Note: when you're done to diagnose, follow step 7 in the article to start on normal startup.

  Method 2: Read the following article to download and install Windows Defender in offline mode

  I have absolutely no idea what the implications are for the AMD graphics card instead of the NVIDIA one card, no one knows what effect this will have on my mac when you use CC After Effects? I've never had this warning on my iMac 21.5 "...

  Is there something I can do?

  Thank you very much, Harry.

  The only thing THAT AE really use the GPU is obsolete ray-traced rendering engine. Very few people use the ray-traced rendering engine. I wouldn't worry about this at all.

  More info here: features GPU (CUDA, OpenGL) in After Effects and here: http://motionworks.net/after-effects-3d-future/

  Now, some third-party plugins (like element, 3D Invigorator, transmutation, etc..) Make use of the GPU, but they will work with the AMD cards and have nothing to do with this warning of CUDA, you want to come. Check that the requirements for all you plan to buy.

  You can confidently check the option do not show this message.

• Archive maintenance brakes not getting enough cycles CPU

  That is the message in the logfile etc on one of my knots in a configuration of two cluster for content server.
  12:16:54.480 05.05 (internal) Archive lock Thread maintenance archive is not getting enough cycles CPU.
  
  Should I be concerned, and if that's the case, what is the solution for this problem?
  
  Thank you, Ken

  The message says that the system of the content server is on (because of the content server or other applications) is so busy doing either one.) CPU use b.) Too much disk activity (space for Exchange, readers of network files, etc.) that the lock held by a thread "heartbeat" cannot get enough time to keep its lock in a reliable way. The problem is surprisingly easy to create on some systems just by starting a bunch of copies of the great repertoire, while the content server is busy.

  A scenario typical where I see that happen is when someone starts a couple of simultaneous batchloads, contained refinery running aggressively and made a lot of check-in. It will also tend to occur more often on load balancing servers. It is usually a good idea to increase some of heartbeat timeouts in balancing environments if the network shared by the server file system is not a file system performance WITHOUT style.

  I don't know if you use this variable of the whole (ArchiverDoLocks = true), but here's some information about it:

  Set to true if you want to auto imports or transfers with more content server then shares an instance. This option enables an algorithm of locking on files to archive at the file system level. If one instance is automatic imports or transfers in a load-balanced configuration, this indicator should not be set to true.
  So I would say that, no, you don't need it if you do not archive on multiple servers

  At the end of account, if you do not no matter what archive between multiple nodes you don't need the
  ArchiverDoLocks = true - try to remove that and see what happens.

  I hope this helps.

• Firefox crashes (even in safe mode) constantly and use 50% CPU while doing

  I use Firefox 36.0.1 and Windows XP (32-bit version).

  Lately, Firefox made this weird thing where it stops randomly load anything, as if the connection has been broken (it isn't, any other works very well). In this case, Firefox uses 50% CPU, when it is usually revolves around, well, 0%. Restart the browser, or waiting for a few minutes "fixed" the problem temporarily. Same thing in safe mode, too.

  I have the feeling that this * might * be related to Flash, since it seems to happen more often when I am watching videos, or stream on the shaking. I tried to disable the plugin-container and update the Adobe Flash Player plugin, with little success. Malwarebytes could not find anything either, and it does not feel like a virus anyway.

  Whatever it is, I'm out of options at this point. I had a lot of problems with Firefox for a while now, especially when it comes to videos/animations (I can't play the videos of Vine.co , for example), and it starts to make it difficult for me. I really don't want to switch to Chrome, I don't trust of Google and their browser doesn't have a lot of key functions I like in Firefox (such as the sidebar bookmarks < 3), so I really hope I can get help here.

  Any suggestions?

  Chrome is a pain, I tried to go back and difficulty of Firefox (so far), and again, I think I found the problem. I should mention that I tried these 5 suggestions before, btw, and none of them got rid of the problem. Yes, even in safe mode, with a profile is empty, no plugins, no firewall and without tab, it happens again, somehow. And Yes, Chrome will work fine with Firefox running in the background, as I mentioned in my previous post.

  What he did for me was turn off Prefetching and IPv6 times in all: config, following the instructions on this this page .

  I'm not sure that one did the trick (I kinda afraid to mess with that again, but I could test if you want to, it might be useful to others), but it looks like everything is going well for the moment.

• Why Firefox for android uses 26% CPU on my laptop when I'm not with her?

• Satellite A500-1GH - what this laptop supports CPU load

  Hello everyone.

  Does anyone know which processor is supported for this laptop?
  I mean the exact models because I know what Intel I5 installed.

  Or maybe if you know the best processor that can be installed in this laptop.
  Are there documents for this laptop because I can not find the drivers in the toshiba site?

  Thank you.

  Hello

  The laptop supports the * Intel (R) Core i5-430 M * processor
  All details can be found on the page of Intel:
  http://www.Intel.com/consumer/products/processors/Corei5-specs.htm

  > Or maybe if you know the best processor that can be installed in this laptop.
  > Here are all the documents for this laptop because I can not find the drivers in the toshiba site?

  Usually the CPU upgrade not is not supported by Toshiba... but if you use the CPU of the same family of CPU (i5 - 520 M, i5 - 540 M), then you should have a good chance that the laptop would be compatible with this CPU... but I would not recommend these updates.

  Why?
  (1) you will not see any performance gain
  (2) you will lose the warranty
