• CPU fan runs at 100%

  Ffan CPU runs at 100%, have installed upgrading Bios according to the support site. Any ideas?

  MartinEA73, welcome to the forum.

  I suggest clearing the CMOS (prn. see moss).  The CMOS is a chip that stores the BIOS settings.  If for some reason, it has not been last updated with the BIOS, it might be causing your problem.

  Because I don't have the model of the computer, I can't provide you with instructions.  Here is a page that will allow you to find them.  Type your model in the space provided.  Then, when the page opens go to the page of the plug to motherboard.  To the bottom of this page, you will find the instructions.

  Hello

  Try Firefox Safe mode to see if the problem goes away. Safe mode is a troubleshooting mode, which disables most of the modules.

  (If you use it, switch to the default theme).

  • You can open Firefox 4.0 + in Safe Mode holding the key SHIFT key when you open the desktop Firefox or shortcut in the start menu.
  • Or open the Help menu and click on the restart with the disabled... modules menu item while Firefox is running.

  Once you get the pop-up, simply select "" boot mode safe. "

  If the issue is not present in Firefox Safe Mode, your problem is probably caused by an extension, and you need to understand that one. To do this, please follow article Troubleshooting extensions, themes and problems of hardware acceleration to resolve common Firefox problems .

  To exit safe mode of Firefox, simply close Firefox and wait a few seconds before you open Firefox for normal use again.

  When find you what is causing your problems, please let us know. It might help others who have the same problem.

  Thank you.

• Modbus IO server causes cRIO CPU to go to 100%

  I have 2 e / s Modbus server set up on my cRIO-9022 system. I use Modbus ethernet to communicate. Each server is intended for a different IP address for the Modbus device to what he's talking about. Modbus devices are configured with these IP addresses.

  In normal operation, the CPU of the cRIO is about 10% use. However, I am trying to build in the correction of the mistakes of my VI. The question I have, is that when one of the modbus devices is dissconnected, the CPU usage gets locked at 100%. I guess that's because the IO server is trying to reestablish the connection and failing.

  What would be the why of the handeling this case to prevent hanging on 100% CPU?

  This is unexpected behavior that appears also when any other server I/O trying to settle the slave as well and I filed a request for Corrective Action with R & D to help resolve the issue in a future version of LabVIEW. A potential solution for those who have the DSC module is programmatically toggle the server I/O with the engine control features available in the palette of DSC.

• my pc CPU running at 100% for all the programs I opened / what is the problem and how to solve?

  my pc CPU fan runs very strongly & the processor running at 100% for all the programs I opened. DO NOT KNOW IF IT IS A VIRUS IN THE PC WAS WORKING FINE A FEW DAYS AGO. How can I solve this issue?

  Hello

  You did changes to the computer before this problem?

  Step 1: Check if the problem persists in the clean boot state.

  From your computer by using a minimal set of drivers and startup programs so that you can determine if a background program is interfering with your game or program. This type of boot is known as a "clean boot".

  Reference:
  How to configure Windows XP to start in a "clean boot" State
  http://support.Microsoft.com/kb/310353

  When you are finished troubleshooting, follow these steps to reset the computer to start as usual:

  1. click on start and then click Run.
  2. type msconfig and click OK.

  The System Configuration Utility dialog box appears.

  3. click on the tab general, click Normal Startup - load all services and device drivers and then click OK.
  4. When prompted, click on restart to restart the computer.

  Step 2: Also, look for error messages in the event viewer. If you find error messages after return the exact error message so that we can help you better.

• Windows XP CPU running at 100% with no open programs

  I use Windows XP SP3 with 2 GB of RAM with a 1.80 Ghz Pentium 4 processor... The computer is VERY slow and lazy most of the time. Sometimes it's fast and the answer but then IT suddenly comes back to extremely slow and lazy - it's as if something is supported of the processor.

  When we look at the performance tab of the the task manager of the CPU usage is running between 80 and 100% when it opens any program or and for the desktop to appear.

  I ran Super Anti Spyware and found 69 threats that have been deleted.

  I ran Malwarebytes' Anti-Malware and it found 1 threat that has been deleted.

  I run ESET NOD32 Anti-virus and it was a clean analysis.

  I run the latest version of CCleaner and cleaned the registry and the tab Cleaner for the cleaning of temporary files, etc.

  I defraged the drive and also checked/fixed for disk errors.

  After that the CPU usage is running always extremely high with no programs open.

  Does anyone have any ideas as to what I can do or check, fix anything that captures the CPU?

  Thank you. Best regards, Bill Artman Kansas City - USA

  What is your system brand and model?

  You may be able to get clues with what is happening by using the Task Manager and maybe understand.

  You will always figure out what happens if you use Process Explorer.

  Download Process Explorer, so you can see what is 'really' currently running on your system, especially behind these multiple svchosts see you in the Manager of tasks running.

  Download Process Explorer from here:

  http://TechNet.Microsoft.com/en-us/Sysinternals/bb896653.aspx

  You'll like Process Explorer when you get the hang of it.  Process Explorer is the Manager of Windows taskbar on steroids.

  Process Explorer installs nothing so it won't slow down your system since it works only on request.

  Process Explorer can seem a little intimidating at first because it has so much information, but you will begin to make love the way it works when you're looking for performance problems.   You can even say EP you want it to be your new default 'Task Manager' value in the future.  You can always run the original tasks as Manager.

  Once you get Process Explorer running, expand the columns, made drag the corners of the screen for it's largest, etc., so you can see as much information as possible in the window.  Now you can really see what is running on the system.

  Here's a screenshot of my system when I use Process Explorer:

  http://img222.imageshack.us/img222/2567/ProcessExplorer.PNG

  The CPU column is usually the most interesting start with performance issues - which uses the most?

  It is OK and normal to have of multiple svchost processes running, but sometimes malware will hide behind them, as the malware knows that you will not be able to spot it in the Task Manager.

  Malicious software can disguise itself also seems to be a legitimate process of XP or he could hide under/behind other processes that you see running in Task Manager if you can't see the execution.

  The malware would trick you into thinking you must use a System Restore Point, run a repair install or reinstall your XP from scratch when you really don't.

  Looking at the display in process Explorer, you want the CPU most to be associated with the system idle process.  It's 'free time' on your system, so more time there, more free.

  If you look at the graphs of performance and see red spikes (or not) double click the graphic in the upper left corner to display the graph to use.  Move the mouse over any pics to see what are the causes.  Even if the Spike has already scroll screen, you can still move the mouse over the edge to see what caused.  You can also just wait for a pic to happen and then see what caused the Spike.

  To help understand your process svchost and what is running under them, read this article and you will be smarter than the average bear:

  http://www.bleepingcomputer.com/forums/Forum56.html

  Then with a few Google searches, you can watch every thing in PE and behind your svchost processes running and see what it is and decide if your configuration needs it or not and then decide what to do about this.

  If you think you have a svchost.exe process amok, executed using PE, you can right-click that offensive svchost, properties and on the Services tab and son, you can see which runs under it.

  There is a CPU column it will expand (make the wider column) so that you can see CPU.  Maybe you can spot what background process is so CPU consumption under the svchost.exe process.   Stroll under the svchost process and you will find it.

  You can also see what is running under each svchost simply by pointing your mouse on the svchost.exe process.  Some of them have just a things working under them and some will have several things (I hope that all the legitimate XP services) and some will have a lot of things.

  If you have a svchost process that is afflicted, which runs under your afflicted?

  No running process must defy reasonable explanation.

  First, see what you can discover using Process Explorer and then if nothing is obvious, see other things.

  Do, or do not. There is no test.

  I need YOUR voice and the points for helpful answers and propose responses. I'm saving for a pony!

• What causes this process runs

  What is causing this process to run?
  
  delete
  FROM CGLOBAL
  WHERE the CGLOBAL.lvisit <: v0
  
  Y at - it a setting the time in the CFADMIN?
  
  

  That certainly looks the result using a database of client variables and allowing the parameter data of the Purge for customers who remain unvisited during the days [n] . I'm assuming that the Purge interval for caces Variables in the server settings controls this.

  Oil change interval
  This option controls how many times ColdFusion executes purge on your client stores. If your client stores are configured to be purged, it is rate at which the operation will be performed. Default is 1 hour and 7 minutes.

• My CPU usuage is going 100%

  OK, I recently problems with m.

  Before my PC used to run smooth, I used to run more than 3-4 programs at the same time. But recently my PC is really slow. Whenever I m using Skype (voice chat) my CPU usage is at 100%, I used to play online and talk on Skype together now is not possible at all. Also, as when I use internet and listen to music my CPU usage is about 70%, which is high! Same thing happens when I watch videos HD, the videos of lag. This happens on youtube, as I can only watch videos of 240 p smoothly. Others do not work smoothly. Usually, when I m not running too many programs my PC is smooth. Also games, games, I used to play before went smoothly today then do not work much more.

  I did my utmost to correct this cleaned up my hard drive, remove all unwanted programs, even cleaned up the dust inside my CPU. And no I do not use anti-virus programs but I hvnt noticed any viruses, just to b problem I installed an and analysed as well but he did not find any virus and yes the anti-virus is up to date, it was the AVG anti-virus don't know how good it is. Also on the internet, I found abt this contraption "msconfig" and a little confused when I run tht so did nothing yet.

  Well, I hope that I have explained the problem well, usually when I do not have anything in the CPU usage is fine as now since I m typing use atm CPU is normal. Hope someone can help me find a solution. :)

  It is prudent to perform at least an analysis of filling with something like Malwarebytes and Superantispyware to make an effort to remove common malware and only when they perform own start to look for other things.

  Assuming you have done this, we learn more about your system (since we don't know anything about).

  As you describe the problem is visible when you CPU and video intensive things such as watching videos, games online, Skype, we will need to know your video subsystem too.

  Since you seem to be able to recreate the problem, if you make an adjustment and your test condition begins to behave, you will know that you are looking in the right places.

  First of all, you have work to do...

  Provide information on your system, the better you can:

  What is your system brand and model?

  What is your Version of XP and the Service Pack?

  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 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?

  Now provide some gory details more:

  Click Start, run and enter in the box:

  Msinfo32

  Click OK, and when the system info summary appears, click on edit, select all (Ctrl-A), copy (Ctrl-C) and paste (Ctrl-V) the information back here.

  For information about video drivers, expand components, click view, click on edit, select all, copy and then paste the information here.

  There will be some personal information (such as the user name and the name of the system), and anything that turns information private for you, simply delete the pasted information.

  This will minimize back Q & A and eliminate guesswork.

  If you have IDE disks, they can back a sort of DMA mode to PIO mode slow, so you must check that too.  Here's how:

  If you are using IDE drives, use Device Manager to make sure the transfer mode for the IDE channels to something as DMA if available (depends on your hardware) and the slow PIO mode.

  Don't forget: PIO is slower transfer mode, DMA is the fastest transfer mode.

  It is easy to check and usually easy to fix and the mode would not have changed in itself, so if she changed to PIO, change it to DMA, and then understand why it changed and fix it.

  To launch the Device Manager console, click Start, run and enter in the box:

  devmgmt.msc

  Click OK.

  Expand the section controller IDE / ATA to see your IDE channels. Right-click on each channel and select properties for each channel that has a tab advanced settings, determine the Transfer Mode. There are usually 4 channels to check in a desktop computer, maybe less for laptops.

  The faster the Transfer Mode selection will be a kind of selection DMA (usually: DMA DMA5, UDMA, etc.).  If it is PIO, change it to DMA.  Be sure to click on OK to save the settings.
    
  If you are unsure of what you see, after return what you see for help and advice.
    
  If you make adjustments, reboot and go back and check the settings again to make sure that any changes you did stick.

  Finally, instead of guess what you might have to startup items and what you might be able to do without, it's easy for you to simply provide a list of your startup items and then get a few recommendations of things that you can do without that, to do this:

  Download CCleaner here:
  http://www.Piriform.com/CCleaner

  CCleaner allows you to manage most of the startup items and also do some other operations oriented cleaning.  Some people will you recommend is not to use the registry functions in CCleaner to avoid these features for now.  I have no problem with it for me, but sometimes it's a contentious issue, I prefer to avoid as much as possible!

  You can uninstall CCleaner later if you don't like it.

  With CCleaner, you can disable the startup items, reboot to see what things look like and if you want - completely remove unnecessary or just startup items leave the disabled while you continue troubleshooting.

  Run CCleaner and choose Tools, boot and bottom right, click on the button "Save to text file" to save the startup information in a text - something like startup.txt file

  Save the boot information text file on your desktop (or somewhere you can find it) open the text file with an editor (Notepad or WordPad), select all (Ctrl-A), copy text, all the text selected in the Windows Clipboard (Ctrl-C) and then paste (Ctrl + V) the contents of the startup list to come back here in your next reply and maybe someone can tell you other things to consider.

  Finally and most importantly, you must be sure that your provider of Internet Service (ISP) provides the Internet download speed you pay for what you can test it by visiting this site:

  www.Speedtest.NET

  Wait that it load and click on begin Test.

  When it finishes, you will know that your download speed and your download speed so tell us what they are:

  Download speed: _
  Download speed: _

  If you pay 10 Mbps and you get only 2, while you pay more than you are getting (you are getting ripped off), so you scream at your ISP and request that they help you fix it if you get what you pay for.

• In "Services.exe" CPU usage increases to 100 percent XP.

  In "Services.exe" CPU usage increases to 100 percent XP. Attempt to disable Load System Services through the system without result Configuration utility, because cpu cannot handle this function before of 'Services' system of pigs. Is there a way to access msconfig. through BACK? Have tried all modes safe mode, same problem.

  I would exercise caution in handling things in the System Configuration utility.  If you disable the thing (s) evil, you could make your problem worse.

  I suggest provide you a little more information on your system, run some scans for malware, then fix what's left more that needs fixing.

  If you see services.exe equips in the Task Manager, suspect malware first, work to eliminate this possibility (with the scans below), then if you still have a problem, we can fix.

  It makes no sense to try to solve problems on a system that could have malicious software on it.

  You can also try to run system restore if you want, but I don't really know, it counts as 'fixing' of the problem.

  Maybe someday the dialog box 'ask a question' forums XP will ask these questions automatically when a new thread is started so I don't have to ask every time.  It might even be possible to solve a problem in a single response when enough information is provided.

  Please provide additional information on your system:

  What is your system brand and model?

  What is your Version of XP and the Service Pack?

  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.)

  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 for malware protection, perform the following analyses for malware.
  then fix any problems:

  Download, install, update and do a full scan with these malware free
  detection programs:

  Malwarebytes (MMFA): http://malwarebytes.org/
  SUPERAntiSpyware: (SAS): http://www.superantispyware.com/

  They can be uninstalled later if you wish.

  The scans by operating clean, then to solve any problems.

  Hello!

  My iMac 27 "has an intermittent problem with the CPU fan runs at full speed. Sometimes it happens at the time when I start it, sometimes only in my session, and sometimes only after a certain time. So does seem to be a problem of "heating".

  Second issue is with the mode 'sleep'. It may occur also at any time, at the start of the iMac, session, or after a certain time. But once he starts to go in mode 'sleep', when I wake up, it goes right back in mode after a few seconds and that it will continue indefinitely until I restart the computer.
