• 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.

• 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

• 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.

  == In the last week, but I know of no specific case of ordinary use.

• Ray-Tracing on GPUS requires a graphics NVIDIA and CUDA 5.0 or later approved. For now, the ray-tracing will use the CPU.

  I just got my Macbook Pro w / retina delivered today 15 ".

  Ray-Tracing on GPUS requires a graphics NVIDIA and CUDA 5.0 or later approved.

  For now, the ray-tracing will use the CPU.

  My mac spec is:

  Memory: 16 GB 1600 MHz DDR3

  Graphics card: AMD Radeon R9 M370X 2048 MB

  -

  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.

• 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?

• CPU is constantly overheating and freezing Satellite Pro A30

  Hi guys,.

  It seems that my CPU is constantly overheating and freezing of the PC.
  (is - what happens when a CPU is overheating?)
  Fans are turn eratically.
  The radiator seems warm enough but still palpable - even if it's just.

  As a trial, I would change my CPU clocked at 2.6 Ghz for
  a slower, cooler to see if it solves the problem.
  Can I just swap, or do I have to change something
  to ensure the new processor running at slower speed?
  Is there anyway I can say that the current of the processor to run
  at a slower speed?
  (I can not even installed on windows
  the PC hangs before the end)

  Thank you
  Ray.

  As noted by James energy saver controls the speed of the CPU and cooling method.
  You can change the settings and check if it will help.
  But a question; How much time do you use this laptop or how old is?
  Sometimes after long use, that dust and debris could have a bad influence on cooling and fan modules.
  For the most part a cleaning cooling module would avoid overheating. But I would not recommend to clean the laptop yourself if you have no experience.
  In my opinion a technician should do.

• Portege 3480CT - can I use faster CPU?

  My Toshiba Portege CPU is supposed to operate at 600 MHz, but for some reason it only works at 500 MHz (plugged - full power). I was wondering if I could buy another CPU say 800 MHz and put it on, nobody knows the fastest CPU this laptop supports. I m using the latest BIOS (2002) and Windows XP SP2.
  See you soon

  Hello Alex

  Unfortunately, it is not possible to upgrade CPU on Toshiba laptops. The processors used in laptops are connected to the motherboard using a process called TCP (tape carrier package). It is a method of permanent connection and is used in the interest of miniaturization and heat dissipation.

  If you want more information on this subject, you can contact the Service partner in your country.

  Good bye

• 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 A45 - the CPU usage is high and slow applications

  Hi all

  I'm trying to debug a hardware problem on my Toshiba Satellite A45. I am running Ubuntu 10.04, but I don't think that it's operating system or related software.

  THE PROBLEM: The CPU usage is high and applications slowly to a crawl after using an intensive application of memory for a few minutes, i.e. to watch a video or a game. Basically, anything that could use the screen much. If instead, I work only from a prompt, even when the application could do a lot of work, I do not encounter this problem. After stopping all applications, the CPU usage is always higher than normal (90% idle, should normally be slowed down to about 99%).

  Xorg now typically showing about 6% (normally use< 2%).="" if="" i="" at="" any="" time="" after="" this="" try="" to="" work="" in="" any="" application,="" usage="" is="" still="" bogged="" down.="" only="" a="" reset="" gets="" me="" back="" to="">

  Note: My system has always worked very well and I did not made the installation of the software or changes when it started to happen.
  However, the laptop is a 800 miles round trip at the rear of the car in a padded bag.

  DEBUG: This doesn't seem to be the RAM that I replaced the RAM and reinstall the RAM, and the problem persists. This doesn't seem to be the hard drive that I can try to run it from a Live CD (without use of HARD drive) and yet everything slows to a crawl.

  HELP: I don't know how to debug from here.
  I don't have extra pieces of hardware to make swaps.

  Any ideas more how to debug this?

  Thank you
  Grommit

  Hello

  > I am running Ubuntu 10.04, but I don't think that it's operating system or related software.
  It s interesting why you think that this may be software related issue

  I think that it is a typical software problem because the RAM and the HARD drive has been verified you have reported this in the message

  So what to say maybe some virus or malware likely to obstruct the CPU and the memory usage
  Or there is some process in the background that are not properly

  I recommend you to reinstall the Windows operating system or another distribution of Linux that runs NO Live CD, but which is installed on the HARD drive
  I m sure that s kind of the process that is disabled and crashes somewhere in the background

• SQLSERV. EXC uses more cpu I have one of my production sql server 2008R2 Server

• WksCal.exe using 50% CPU

  Overview of resources shows that WksCal.exe uses 50% of the CPU resource. For a feature that I even don't use it seems to be down. I know that I can turn it off, but I'm more interested to know if this is an indication of other problems.

  Hello RobtC,

  Thank you for posting.
  wkscal.exe process is the civilian component of MsWorks. It works similar to a traditional calendar, which allows you to schedule meetings and set reminders etc. If you find useful MsWorks calendar, you must leave the wkscal.exe running process.

  My theory as to why it would be to use 50% CPU, is that it could be synchonizing with a mobile device as in the link here

  Please let me know if this has been helpful for you.

• 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.

• 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.
