  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:

  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

  Firefox (v30.0) normally uses the CPU of 2 to 6%.
  When I start a video using shockwave flash 14.0.0.145, firefox uses 20 to 40% of the CPU and shockwave 50-80%.
  For the most part resulting in a total of 100% CPU usage.
  This problem occurs for a week or two.

  I think first we should know something on your system, then you should run some respectable malware removal tools and then only start troubleshooting of any problems (unless you just want to start guessing and try things).

  Because the Microsoft Answers forum does not have any kind of information system request when a new question is asked, we know almost nothing about your system.  Not knowing the basic information a problem prolongs the frustration and the agony of these issues.

  Thank you MS Answers, allowing the resolution of simple problems as frustrating and a lot of time as possible.

  Provide information on your system, the better you can:

  What is your system brand and model?

  What is your Internet browser and version?

  Your system's disks IDE or SATA drives?

  Describe your current antivirus and software anti malware situation: McAfee, Symantec, Norton, Spybot, AVG, Avira!, MSE, Panda, Trend Micro, CA, Defender, ZoneAlarm, PC Tools, Comodo, etc..

  The question was preceded by a loss of power, aborted reboot or abnormal termination?  (this includes the plug pulling, buttons power, remove the battery, etc.)

  The afflicted system has a working CD/DVD (internal or external) drive?

  You have a genuine XP installation CD bootable, which is the same Service as your installed Service Pack (this is not the same as any recovery CD provided with your system)?

  If the system works, what do you think might have changed since the last time it did not work properly?

  No matter what you use to antivirus/antimalware protection please follow these steps:

  Download, install, update and do a full scan with these free malware detection programs at:
  Malwarebytes (MMFA): http://malwarebytes.org/
  SUPERAntiSpyware: (SAS): http://www.superantispyware.com/
  They can be uninstalled later if you wish.

• 35.0 Firefox uses 100% cpu on Mac Yosemite 10.10.1 then either breaks or needs force quit.

  I had this problem since installing Yosemite and using 34.0.5. I upgraded yesterday to 35.0 but still the same problem. Firefox will work happily for a while and then all of a sudden will use 100% cpu. I disabled all extensions and plug-ins and that made no difference. If I use Java (8-25), it will usually make it crash but not always.

  To make things worse, the accident report appears in Greek (which is considered in another question already).

• Why Firefox uses 100% CPU when I am connected to eBay?

  Firefox uses 100% CPU when I connect eBay.

  Hi apdubois, it is useful to know that Flash is the problem but, as you point out, life without Flash is not very interactive.

  It is a standard orientation that addresses the most common reasons for problems of Flash in Firefox. I'm sure you've seen some of it before, but just in case:

  (1) make sure that all recorders/downloaders who interact with Flash media are as up-to-date as possible, or disable them temporarily.

  (2) disable graphics hardware acceleration in Firefox and Flash

  (A) in Firefox, uncheck the box here and restart:

  the button Firefox orange (or the Tools menu) > Options > advanced > General > "use hardware acceleration when available.

  (B) in Flash, see this article from Adobe technical support: http://helpx.adobe.com/flash-player/kb/video-playback-issues.html#main_Solve_video_playback_issues

  (3) turn off protected mode (Windows Vista/7/8)

  See this article from Adobe support under the heading of 'Last resort': Adobe Forums: how to fix protected Flash Player for Firefox mode?

  In the resource window, I see that there are five entrances to WksCal.exe and they use 100% CPU.

• Creative v2.2.0.129 desktop application of Cloud using 100% cpu

  Often I find creative cloud desktop idle app will be ramped up use 100% cpu for one of my cores on Mac OS X 10.10.5
  There is apparently nothing to do and I'm not using the synchronize file CC, the only thing I use the CC app for updates of applications.

  When the application pegs my CPU I usually double check that it is the culprit in the activity and then monitor exit. It's particularly annoying when that happens on the road with my Macbook Pro because at least that I pick it up quickly it makes my shorter than expected battery life.

  Does anyone else know this?

• Why my always 100% CPU usage and what is RegSvcs.exe uses 50% of it?

  Hi people,

  I think I need urgent help though.

  Recently, I thought I downloaded malware that is injected with the Trojan horse. And now, I believe that the Trojan horse lies in my computer. I did this because my CPU usage is always at 100% even when I just restarted my com. Initially, I found there was a program called dgen.exe running in my computer to a 60% of CPU usage. Never so, I remove the dgen.exe from my computer but I don't know if I remove it entirely. Now, I'll have another program called RegSvcs.exe in my computer operating at 50 percent CPU usage. I googled out and it says it may or may not be required by windows and it could be a trojan virus as well. That's why there at - it anyone who can enlighten me on this?

  I have to delete or to update or something?

  Thank you.

  Kind regards.

• Satellite A40-231 - 100% CPU usage when any browser works

  Hello
  my laptop is satellite A40-231, I have a problem for days.

  When I open any browser (I tried firefox, IE and chrome) I can't watch the video, everything is slowing down, I can't navigate between pages.

  I took a quick glance to the use of the cpu and it increase to 100%, it never decreases. When I close the browser, the CPU usage drops to 15%, which is normal. I thought it might be a virus that internet connection and make things slower. That's why I format my laptop. I deleted all of my hard drive and reformatted. I installed Windows again, but he has not changed. I even installed ubuntu (I thought maybe virus can not work under ubuntu), but it's the same thing. I turn on my laptop and I open a browser and the laptop slows. I have clean the cpu fan it has not helped.

  I tried to solve it for days I could not sleep properly, I'm about to cry :(

  Please help me please.

  Hello

  You have reinstalled Windows using the Toshiba Recovery disk? This drive will restore the settings from the factory with all the drivers and tools so everything should work fine after that.

  In addition this happens with LAN or WLAN connection? You should try it with the other connection.
  Also check your router and update the firmware. Try to disable the encryption, MAC address filtering, etc.

• Why my svchost.exe process constantly runs at 100% CPU usage?

  Recently, my computer was extremely slow.  I thought that was the cause of a worm or virus but after I used Norton to take care of that my system is still slow right too. When I checked my system process, its display svchost.exe using a massive amount of memory. Therefore, my CPU usage is constantly at 100%.  Is it still the result of a bug? Or do I have to look elsewhere as the source of the problem? Thank you

  It is possible that a recent update of Norton was faulty or caused one conflict with another program on the PC.

  Activity excessive svchost.exe is often linked to one of the following:

  1 resource hog like Norton or McAfee (sad but true)

  2 be linked in Microsoft Update instead of Windows Update

  3. after having been updated for Windows Search 4.0 and its endless reindexing

  4. the presence of malware

  Unless you have uninstalled Norton AND used their removal tool, I doubt you really deleted ALL occurrences of Norton!

  FWIW, I helped a neighbor recently with his performance problem. The culprit in his case was Windws Search 4.0. And since there is no entry in the Control Panel Add / Remove programs to KB940157, I needed to follow the instructions offered by Nepatsfan here:

• Svchost.exe causing 100% cpu usage during the update of windows, even when disconnected.

  I recently had to re - install windows xp on a new hard drive for replacement. My version of xp home edition, SP2 OEM installation disc. (This is ith group included IE6)

  Once installed and running, could access windows update.

  Read all the threads associated etc. and installed SP3, disc after downloading microsoft on another pc. Installed after three trys, first two caused various mistakes, but third attempt seems OK!

  I've also updated the IE6 to IE8, as some sites obviously did not work properly with the older browser.

  Now go do the automatic updates, or log for manual updates... BUT!

  During the process, my cpu fan comes on fast and permanently! The CPU usage is showing that 100%, pc slows to crawl, the mouse becomes slow etc.

  This has never happened before on this machine before you reinstall clean, he had already automatically updated to SP3 and went very well, it was some time ago, before the failure of hard drive, and it has never had this problem!

  Only since having to do a cleaning manual update and re - install.

  The culprit seems to be svchost.exe, once it is used by the update, running the cpu at 100% and continues to do so EVEN after stopping the service, until I manually stop with the Task Manager!

  The svchost.exe instance showing a high is use: SYSTEM.

  According to the files of help here, it is a known issue and a fix KB927891 was issued for SP2, but this should NOT be necessary for SP3, and in fact difficulty used to perform anyway under SP3!

  Ideas for a guy to fix?

  I appreciate the support for XP runs out quickly, and after this update of windows will be redundant, but in the meantime it is always useful!

  Also if I turn off the automatic updates, how can I stop this annoying popup warning bubble?... I can't live without updating, but this bubble nag drives you nuts! :)

  OK just a update, now running cool and 100% auto update and manual update... How? I hear you ask...

  Well I had a beer and a reflection and came to the conclusion, it must be 'order' in which I updated the clean installation of XP.

  Origin, I loaded the old OEM disc new hard disk, loaded the drivers etc, then stop at windows update for updated files.

  Who told me my old incompatible browser and suggested an upgrade.

  I downloaded and installed IE8... still no joy, reading the forums comments I downloaded and installed SP3... which SEEMED to work, BUT then all the hassle of cpu to 100% with the automatic update and updated manual on the windows don't update site!

  So I just gritted my teeth, formatted the drive, another OEM of XP Home Edition SP2 installation loaded the drivers, installed a copy saved to SP3 and after restarting, THEN installed a saved copy of IE8 and THEN trotted off the coast to the windows update site... low and behold, it the connection without problem, did a search, and required updates appeared on the screen without delay all 123 of them...! :)

  Did the updates, restarted and everything was fine, updates automatic in market and left the machine, after about 30 minutes appears the yellow shield, and it downloads a couple more update files without problem.

  All this time I followed the via the Task Manager CPU usage and the strange spike waited 100% apartment, it was on average from 5 to 20%!...so a great improvement has this effect, by simply changing the order of the updates installed from the original! SP3 IE before IE8.

  May not work for all have to do a clean install because of the HD failed, but its worked for me, and I am once more a "happy bunny!

  Dave was soon.

• 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

• Vista Enterprise using 100% CPU countiniously

  I use Vista business on dell Inspiron 6400 (had vista with laptop). The laptop has dual core processor and a CPU is used 100% without interruption since install. I have installed all updates using windows update utility. I have also disabled the indexing service and also to adjust Visual effects for best performance. The problem still exists.

  In the Task Manager, I see a peremptory touch 100% CPU graph and another pretty normal CPU graph. I have 2 GB of ram and still 1,3 GB free. I have not yet installed any software. In the list of process System Idle Process takes, 90 + CPU usage no other program uses much CPU.

  For this reason, my laptop is very slow to respond and almost useless, please help me.

  I think that I found the correct culprit this time. I tried to disable the edge of BIOS devices implemented and it worked. When narrowed "Media Card and 1394" device was causing too much hardware interrupts. My PC works fine and no CPU usage after you turn off the device. I think that the fault was in Media card on board the aircraft.

  It took me a long way to reach this solution, so to help others here you are a few steps to take to limit the problem.
  -Task Manager open to see if any software uses the CPU more than expected. If you notice any software then its easy to uninstall or disable the program at startup etc.
  -If Task Manager processors are normal and yet one or more CPU is used close to 100% and then download and run http://live.sysinternals.com/procexp.exe ProcessXP and run
  -If material interruptions take up too much cpu, then try to disable/remove your attached devices, like modems usb, wireless lan, lan card BIOS Setup etc.

  Hope this will help.

• Older games causes rundll32.exe to open and 100% CPU usage

  Gameux.dll, Rundll32.exe, the CPU usage and no internet! : D what a pleasure!

  From some (mostly older) games rundll32.exe causes opening with Gameux.dll and is 100% of the CPU usage. I know that it's because she's trying to connect to internet, I did not. What is my alternative to make my games work again! I want to delete game explore all together, but Microsoft didn't really care to add such an option. If I can't find out tomorrow night, I'm going to start in a 2nd OS and delete the dll, and if Win7 stops working, I will be switching back to Windows XP.

  All the solutions!

  I thought it was a pretty well known problem that the Games Explorer does not work in offline mode? He opened Rundll32.exe to run Gameux.dll and idling with 100% use of a nucleus. I think that this problem has been around since the beginning of Windows Vista (or at least since the dawn of Windows 7, not tried this problem under vista).

  WHAT, for anyone reading this in the future (Google or otherwise), I found a Solution. (Not a pretty, I take no responsibility, but it worked twice for me).

  I went into the registry (Regedit.exe)
  CTRL + F (find)
  Looking for the GameUX,
  and whenever she finds one, I deleted it. excluding results within areas such as "{xxxx-xxxx-xxxx-xxxx-xxxx}", no need to remove those. but all other entries GameUX, including directories (not sure of the term suitable for registry entries)

  Anyway, long story short, I fixed it by removing each entry in registry GameUX that I could find. all games work now, even offline! : D
