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

• 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).

• Firefox using 50% + CPU when it is idle and stops when I close and reopen; then he resumes it after that that he is responsible for some time.

  With Firefox loaded, but sitting idle for a period, he began to use 50% + CPU (by Windows Task Manager). This slows down everything even if nothing happens (openly) with Firefox. If I close and reopen, it's OK for a while, and then it starts again.

• WksCal.exe using 100% CPU

  In the resource window, I see that there are five entrances to WksCal.exe and they use 100% CPU. I thought I had solved in part this problem yesterday when I got rid of all but one of these entries. Today, they are all back. I did a full scan on my computer by using the Windows program and found nothing.

• 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?

• Firefox and Shockwaveflash 14.0.0.145 using 100% CPU

  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 am running Microsoft Vista.

  You can check for problems with the current versions of the plugin Shockwave Flash and try this:

  • Check updates for your drivers drive graphics
    https://support.Mozilla.org/KB/upgrade-graphics-drivers-use-hardware-acceleration
  • Disable protected mode in the plugin Flash (Flash 11.3 + on Windows Vista and later versions)
  • turn off hardware acceleration in the Flash plugin

• 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.

  By far, this is related to the Malwarebytes with steam being far behind.  Your Cpu & your HD and combination of slow down the computer.

  I would remove MBAM at least to test

  

• Why firefox uses so much memory?

  For several months, Firefox has eaten memory like crazy. Once I get more than 5 tabs open or that you have Firefox running for more than an hour, the memory usage hit about a GB. If I continue to let go beyond that, it will hit 1.5 to 2 GB and it made my gel set office. I got to keep the Task Manager and every hour or so just kill Firefox and restart. Preventing it from crashing my whole desktop computer. It's definitely worse when I opened Google products, especially maps and Docs. GMail is generally OK.

  I tried to disable literally every add-on and Extension (including Flash and Adblock).

  I'm on Windows 7, I have 4 GB of RAM installed. I am on version 40.0 Firefox, but this has happened through a few updates now (I think the problem started around March or April). I also tried to back - rev Firefox and go to the latest version, that I had before the problems started, but that did nothing either.

  Chrome works fine on this machine without any similar problems - but I prefer Firefox!

• I am running xp family on an old PC 7yr. Task mgr shows Im using 100% CPU resources veryenen, resulting in slow or frozen PC. Seems there are 60 at bottom. KS

  How can I reduce the number of processes running in the background? 100% CPU often allows. Thank you

  Use Autoruns to understand this all starts when your computer's / when you log in.  Look for whatever it is you do not know using Google (or ask here.)  You can hopefully figure out if there are things from when your computer does (or connect) you don't not need and then configure them (through their own built-in mechanisms is the preferred method) so they do not - start using your resources without reason.

  You can download and use Process Explorer to see exactly what is taking your time processor/CPU and memory.  This can help you to identify applications that you might want to consider alternatives for and get rid of all together.

• 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.

  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

• 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.
