  I have:

  Disabled Windows Firewall and Avast antivirus.

  I tried all the things as well in safe mode.

  Installed costs.

  Followed the instructions found on the net

  In offline mode, downloaded and installed the latest update which is the same as that.

  Whenever I have restore before this update, it works very well. The download of the update even if I have restore and install only the off-line version, it cripples even with 100% cpu and without end of audit. He made also Defender without end of audit.

• 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!

• (fontcache) Svchost.exe using 99% cpu

  Hi, I'm running Windows 7 Ultimate x 64. Randomly, the svchost.exe (fontcache) service will start using 99% of my cpu, everything a lot. Specifically, it starts happening when I play Team Fortress 2, but it also happens while I play the game. During a match, making the game lag, giving me a very large ping 2000ms + and no fps. If I end the process, it stops and is fine. But it could be the cause?

  Common programs, I have running at all times are as follows:

  AVG anti-virus

  Pidgin (AIM client)

  Skype

  Google chrome

  Windows media player

  Any help would be great, it becomes annoying random having my computer be bogged down for no reason. Let me know if you need more information

  Thank you, xJedix

  Hey guys, thanks for the suggestions.  Actually, I found another person who had this problem.  Their solution was to remove the additions of the shell that nvidia added to when you right-click on the desktop and things.  This has solved the problem, at least until now...  It's 3 days now without problem and also fixed my problem Explorer.exe crashing several times when I was reviewing the files :)

  If anyone is wondering how to disable programs that have been added to the hull, use shexview.

• TosBtProc.exe using 100% CPU

  I have a Tecra with built-in Bluetooth 9100, running Windows XP SP2 however, everytime I turn on the bluetooth, using the system tray icon the TosBtProc process starts to use 100% of my CPU and pipes of my machine unless I kill the process.

  This problem was happening before that I updated to SP2, I tried upgrading to the latest v3.20.01 Bluetooth Stack but that made no difference.

  As a result, I can't connect my Bluetooth phone to my PC.

  Does anyone have ideas, what is the problem?

  Hello

  It's very strange. I have Tecra M1 and it resembles your T9100. I tried to go wireless and Bluetooth connection, but everything works fine. Can you please try the same thing using FN + F8? Use just the Bluetooth wireless as there is option that allows connections on the same time.

• svhost.exe causing 100 cpu

  My computer is running at a snail pace because the svchost.exe uses 100% cpu ALL the time.  It's almost impossible to open and close programs.  I'm only able to use my computer if I stop the process through the Task Manager.  I would like to find a fix for this if possibel so I didn't complete the process each time I want to use the computer. O running all tests antivirus and registery scans I can think.  I thought it must be some kind of virus, but I can't find anything.  Help, please!

• Explorer.exe and svchost.exe using too much memory

  I have disabled the automatic updates after the last round of updates, and now, all of a sudden, explorer.exe and svchost.exe use too much memory... enough to interfere with other programs, I try to use.

  Help?

  Windows XP Professional - Svc Pack 3 processor: Intel (r) Pentium (r) D CPU 2.80GHz CPU speed: 2.73 GHz memory: 512 MB

  Why you turn off automatic updates?

  There are between the two options. I just set it to notify. When it is practical, I go to the Microsoft Update slte and use the custom (not Express) option. This gives the user full control of the update of trial.

  You will have a better idea of the cause of the problem using Process Explorer.

  Download Process Explorer.
  For more information about Process Explorer, see here:
  http://www.Microsoft.com/technet/sysinternals/SystemInformation/ProcessExplorer.mspx

  With svchost.exe provide us a list of services using the process. There are number of processes that are using svchost.exe, so we need to know that we provide more targeted assistance. Right click on the process, click on properties and look at the Services tab.

  Solution Explorer. exe has a number of subprocesses. Select the sub-process, click Properties and check the Services tab.

  Have you recently changed all types of starting any service. This often leads to the problem. Users often disable a reflection of service to speed up the system performance. In practice what is done is of one or several programs to malfunction.

  Hope this helps, Gerry Cornell

• 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).

  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)

  Hi Cyndy62,

  1. When did you start to question?

  2 did you a recent software or changes to the material on the computer?

  Step 2:

  If you are not faced with the question in safe mode, then you can try to perform a clean boot and see if it helps.

• 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?

  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.
