System interrupts hogging CPU at 100%

I searched high and low for a solution to the problem plaguing my laptop.  The CPU is * always * on or close to 100% usage.  This problem came all of a sudden... I took my laptop to work to use it to listen to music.  It worked very well at this point.  I left the room for a few minutes and the computer has been restarted itself... and when it restarts it was slow slow slow!  Like a fool, I only use GoBack or system restore.  I searched "solutions".  It has been almost 3 weeks now where this machine was as slow as molasses.  I used to be able to watch DVDs and YouTube videos... now I can't because the image and the sound is so rough!  Arggh!

They advised me to download Process Explorer... and that's where I learned the system interrupts on this system is unusually high.

In any case, I have tried several solutions.  I defragmented almost daily (I know, exaggerated).  I ran SpyBot, Malwarebytes, Avira and Auslogics Boostspeed.  I ran the disk error checking and control.  I have updated the drivers.  I removed the programs and files to try to free more hard disk space.  One solution was to do a registry editing (the steps that follow).  I did this and then he defeated due to advice from someone on another forum.

1. go in the Device Manager (right click on my computer > properties > Hardware tab > Device Manager).
2. expand IDE ATA/ATAPI controllers and click primary IDE channel;
3. click on the properties button and select the tab advanced;
4. If the PIO, and DMA Transfer Mode, this is your problem;
5. let the open properties panel.

The solution is relatively quick and painless. It requires two successive reboots. Just make sure you follow until the end, or the problem will return.

1. open the Registry Editor (start > run > regedit > OK);
2. expand HKEY_CURRENT_CONFIG/System/CurrentControlSet/Control/Class / {4D36E96A-E325-11CE-BFC1-08002BE10318};
3. Select 0001, then click Edit > New > value DWORD;
4 Type ResetErrorCountersOnSuccess, and then press enter;
5. click Edit > modify.
6. type 1 in the value data, and then click OK.

This should solve the problem with interruptions and make your system work a lot better.

A person on a forum for tech support suggested I have a scanner with PCPitstop.com... what I did... the results can be found here (if this info can help you solve my problem).  The link to my scan is here: http://pcpitstop.com/betapit/sec.asp?conid=24432482&report=Summary

I'm at a loss to know what to do.  I've lost my CD of Windows - they're 1000 miles away with my parents.  I don't even know that if I have a real installation CD - Windows XP Home Edition was preinstalled on this laptop when I bought it.  As the backup of the system CDs (1000 miles) I know for sure, I have are, I did when I first came to this system.  I don't have enough money right now to buy a new computer - especially when I know this HAS to be a way to fix - the problem came all of a sudden!  Relocation is not an option because I am away from my backups now - and can get them in the mail for over a month.

Can anyone help? Thank you!

Woo - hoo!  Fixed!

  • Windows 8 system interrupts high CPU usage

    I have a new laptop - Hewlett Packard - with 8.1 Windows 64-bit installed and updated, I bought a month ago.  I had major problems with it getting more slower during a day until it has reached the point where it literally comes to a grinding stop around what this time of the evening.  He has a lot of RAM and processing speed, so I'm very surprised that it is having this problem.

    I had a glance at the Manager of tasks and processes and found that "the system interrupts" always uses between 30 and 40% of the CPU, even when I don't have any other programs open.  When I add Firefox to the mixture, between her and the system interrupts, the CPU runs at 80% capacity all the time, which is why it is grinding to a halt.

    I looked at other issues in this topic on this forum, but the answers don't make much sense to me - especially those who blame it all on 3rd party software, which seems a little too convenient for me.

    in any case, I would like to help please with this problem.

  • The processor high/weird CPU usage and about 20 to 25% system interruptions.

    Hello

    I use an AMD phemon IIx4 965 processor. (never had proplems with this till now.) One of its mainstays bed use ranging from 70-99% in Task Manager exercising while the other 3 are normally working / reading normal numbers. The question comes at random, but won't go away unless I restart my computer. This problem arises in a week a go, I was playing a game in steam when I noticed the drastic performance to fall and began studying. The question, something just when im not playing. I use my computer mainly on the game. The computer slows down because of this. I have no idea what the cause. Help?

    Procexp said interruptions system 20-25. According to CPU - Z and CrystaldistInfo my HARD drive temperatures are all normal, around 28 - 38 c idle.

    Reasently, I got a new case for my computer parts, I removed and passed my components of my old case to a new. I tried to be careful and I know (I know) thinki. enough computers to do this by myself. Fifi, it done once in the past. I have read the instructions and put / connected all the wires and parts according to them. The machine started normally. No problems. This could cause this problem, is a thread in the wrong place? I do not know.

    I used free versions of Windows security essentials and Spybot search and destroy, Avast kernel tdsskiller to search for viruses and malware. All this happened in own. Can he still be a virus or something?
    Used more claire Wise registry and Ccleaner but noting alarming is come to the top, (again I think.) some things Yes, but breaking the ' fix claim has pursuant button has not set a cpu problem.

    First I though its my GPU causing the problem drivers. (google said) Approximately 45 days only a go replace my old AMD for a new R280 AMD Radeon 6950. Allworked very well so far. I found that according to Unknown Device Identifier I had older drivers still on my machine. I had trouble removing the old drivers, but eventually I had to use an uninstall program display driver for getting rid of them and now I only see one set of drivers. This has not fixed the issue of the use of the cpu.

    IM lost, at the end of my skills (mainly google-fu). Can someone help me? I hope this is the right place for this post, if it isn't then I apologize.

  • Use high CPU (35% average) while System Idle process CPU about 98% but frustrated by "[name of the prog] has stopped working".

    Hello

    I am trying to help someone with a laptop HP model g6-1202sa (Windows 7 Home Premium 64 - bit, another record at the end of the post).

    I think that Windows is now updated and drivers, but the problem remains also.

    The laptop has the symptoms mentioned in the title I found the Manager tasks.  Laptop fan is on a large part of the time, and the owner says that, during the execution of something more intensive than Skype for example of internet browsing, they get a warning from Norton on high CPU. Resource monitor shows that system interrupts are on average about 31% CPU.

    The results, I found the task manager has led to some research on Google, which in turn led me to want to run adksetup.exe (Windows Assessment and Deployment Kit) in the hope of discovering if a particular driver is causing the problem. (Various threads on the internet point to what is the way to go).

    However, after downloading adksetup.exe, when I try to launch it I get the initial screen of Toolbox and then 'assessment of Windows and the deployment for Windows 8.1 Kit has stopped working ". (Verification of the solution finally gives the only option to "Close the program").  Similarly, I have now discovered that if I try to look at the properties of the computer, i.e. start > right click on computer > left click on properties, I get "Windows Explorer has stopped working". Do more research on Google I find sometimes I get "Internet Explorer has stopped working" sometimes (Chrome is ok).  More out of curiosity than anything specific I ran AMD VISION Engine Control Center after right click on the desktop and ended with 'Catalyst Control Center; The host Application has stopped working".

    So before going any further, does anyone have any ideas what's happening?   I do not understand the problems 'has stopped working"in safe mode, but the high utilization of the processor with System Idle Process around 98% is still there.  It appears so that I can run adksetup.exe in safe mode while this would be the way to proceed and continue to try to tackle the problem of CPU?

    For the record, some of the things I've done along the way include update of Windows, updating drivers, running the file system (no violation of integrity) checker, a regular chkdsk ("CHKDSK discovered free space marked allocated in the master file table (MFT) bitmap. Correcting errors in the volume bitmap. Windows has made corrections to the file system").  Swapped the only module memory 4GB 2 x 1 GB modules I had to hang out, all the symptoms remained 4 GB then reinstalled.

    Thanks for the tips

  • Firefox 13 hogs cpu all of a sudden

    Good, everyone.

    I'm having a terrible experience with the new firefox 13, and I was wondering if others are experiencing the same. FYI, I use Windows 7, i7 and 8 GB of ram.

    After the auto-update, after 10-20 minutes in navigation, my hard drive (SSD) is committed completely full to make my useless computer. Everything is unresponsive, and the only thing I can do is hard reset.

    I tried to uninstall FF 13, but the same thing would happen with IE and Chrome. So I did a system restore. The good news is the problem drive HARD to gone, but after the auto-update to FF 13, I realized that the computer is awfully slow. I opened my resource monitor, and wow, FF is pretty much drive the CPU at 100% constantly. I have disable FF, and it is fine. On FF12, I would more than triple number of tabs (40 +) compared to now open (12-13), but it wouldn't make my slow computer.

    It of a bit frustrating because the framework and extensions are the same front. The only difference is the new Firefox.

    Everyone knows the same thing?

    Yes, I already tried all those. That is why I asked anyone suffering from the same problem.

    But I found the solution. Given that my CPU was used 100% of the time by a browser, I wanted to check its condition (temperature, speed, etc.). I discovered that the CPU has been limited to 800 mhz to 3.2 ghz. There was a problem with the adapter sector and power insufficient throttle the CPU.

    I should have done this first test, but I don't think a lot since the decrease in the speed in the other application was barely perceptible. Well, I'm glad Firefox wasn't the problem.

    Anyway, madperson, thank you.

  • S50 satellite - B PSPQ6E - high interruptions on CPU

    Bought a Toshiba S50 - B (pspq6e) yesterday, when I booted the system I noticed that it wasn't in reaction time. I decided to install windows 7 on it, after that only she remained slow with many interruptions of the cpu (atapi.sys, ndis.sys).

    Things, I tried to solve this problem:

    -updated the bios to 2.0
    -install windows 7
    -disable the cpu Accelerator
    -install the drivers 1by1 from official support section of Toshiba
    -install the latest drivers from the factory

    even after doing a format without having to install drivers, interrupts are there so I guess that it is a bios related or hardware problem.

    Any advice would help

    With sincere friendships.

  • Satellite A100-784 (PSAANE) - CPU is 100% most of the time

    Hello

    I have this Toshiba Satellite A100-784 and it has Vista Home Basic as the operating system. The CPU is at 100% most of the time, and I don't know what to do more (I've eliminated all unnecessary programs that might have a background process). Sill, form 100% of the CPU, the core load takes 40 to 60% most of the time.
    I thought to install XP to make it work, but after reading the forum is not that simple, due to the fact that the HARD drive can be SATA.

    Can you help me with this situation? I can hardly work on this laptop and I think to change the brand if I don't find a solution to this, even Toshiba is my favorite.
    Thanks for your time answering this problem.

    Kind regards!

    All you have done is just, but you must understand that no one knows here Setup OS and what you've done in the past.
    If you are not satisfied with the way in which your laptop is now running the best thing you can do is to back up all your important data and install Vista using delivered Toshiba Recovery CD/DVDs.

    After doing this you will own preinstalled OS and everything should be OK again.

    MalwareBytes's AntiMalware - no AntiVirus. ;-)

    Probably your best bet - flatten (wipe) the system and start from scratch.  You will need your most recent backup (your stuff, like your documents, photos, music, video, spreadsheets, databases, presentations, bookmarks/Internet favorites, e-mail contacts, serial number, proof of purchase/receipts, that may have been scanned in, etc. and so on...) and a good list of installed software and hardware specifications (I suggest Belarc Advisor running on the current system and print the results if possible) then you can get the drivers before or after installation.

    Of course, you will also need your multimedia installation product key/serial numbers and that go hand in hand.  In Windows XP - there is no way for me to know (without telling you) what level your installation CD is... so you will need to install the SP2 and SP3 after installing the operating system.  I would leave it disconnected from the Internet (physically) until it is at least SP3 and you have confirmed its firewall is enabled and, if possible, you have installed an antivirus application.

    For you, I suggest the eSet 32 antivirus (not more) - which costs ~ $60 every two years for private users.  Add to that the MalwareBytes full package which costs, if I remember, ~ $25 for life.

    Then, once the system * is * connected to the Internet (physically) - get hardware drivers installed for everything and the rest 100 + installed post-SP3 updates.  Then you can worry about all your other programs and restore your files LAST.

  • "Task manager" and Norton AV cpu use 100% constantly, always etc.

    I'm looking at my roommate pc and same problem. under Win XP, SP3.  To run any program takes about 5 full minutes.  CPU use 100% in Norton Anti Virus (NAV) or the Task Manager.  For now I'm just using taskmanger to see the %.  The only way to get to 0-2% is to restart in safe mode.  Go to start/run and msconfig, checked the only button "Load System Services", is went to 'Services' tab, hid Microsoft services and disabled all services, and then restart.  The 100% cpu is always attached to 100%, but the pc certainly significantly faster programs. (almost normal)  Does anyone know how to fix this?  I ran a full NAV of the system scan and a spybot search and destroy scan which finds that some cookies.  Any help would be greatly appreciated.

    Dear Palcouk, I found the problem.

    For someone who has either taskmanager/Norton AV and it shows cpu 100% stable, but when your pc is restarted in safe mode (press F8 repeatedly after reboot), it seems to fall to 0-2%.  Download and run Process Explorer. Once executed with your cpu showing 100%, look under the CPU column.  Regardless of the program see you running the stronger use of the processor is the problem.  You can check this out, as I did by right clicking and "kill process".  Then check your CPU usage again.  Must be 0-2%, which is normal if you are running many programs.  In my case of roommate when I flew over the mouse program svhost using a 99% cpu, it has demonstrated a program that comes from a HP servoce.  It turns out that she has recently reinstalled the drivers of hp printer and somehow it corrupted his PC.  The fix was to reinstall the HP software on write corruption because we were able to uninstall all HP software.  She told me that she was trying to 'fix' the software earlier, but it's probably where corruption has come.  Problem solved.

    Thank you

  • Use Windows 7 CPU to 100% only when it is plugged

    I post this topic only because my problem is quiet unusual. I found hundreds of topics related to 100% CPU usage in Windows 7, but none of them was related to this over-consumption of the processor during the charging of the battery. There is also a situation that 100% of CPU usage occurs while working on the battery, but my case is completely the opposite.

    Windows 7 x 64 prof. system goes to 100% CPU use occasionally and it becomes impossible to work. then all of a sudden, the problem goes away and everything works right. After a few days of work without problem the problem returns and so on. I did the fresh install several times and the problem appeared immediately after the installation of the system every time. Finally, I discovered, that it lasts only when the charger is plugged in when you are working on the battery, everything works correctly. pluggng immediately after the CPU reaches 100% usage and so on.

    Help!

    Hello once again, Andre. Thank you for helping me. I tried to find such a framework (high precision event Timer) in my BIOS, but I did not: it seems to be fixed on my laptop. However, I found it in my Windows Device Manager and I have disabled HPET here, but it did not help in any case - there is no change in the use of the CPU (always 100%).

    BUT - I found an effective solution on my own! The thing was very simple - it was the fault of my power cord to the AC adapter / CC. I tried my colleague adapter and CPU usage dropped sharply to 5-10% on idle. Then I plugged my power adapter - use has exploded to 100%, and again, I used my colleague adapter - use declined.

    THE REASON FOR THE HIGH IN MY CASE CPU USAGE WAS DEFECTIVE AC ADAPTER

    It was a big surprise for me, because the problem occurred only from time to time. Apart from this, the laptop work properly. I tried hundreds of things, including the reinstallation of the system 3 times, change a hard drive (which seemed to make some strange sounds), my memory test, install the latest drivers from HP, change settings loading, etc. Only after buying a new battery (the old one was not operation at all) I noticed that the problem goes away after unplugging the AC adapter.

    I lost a lot of time trying to solve this problem and it was very frustrating, I also found that a lot of people have similar problems, so if you, dear reader, have 100% CPU use problem, unplugg your power adapter first know, that it's abandoned.

  • After awhile java.exe is the CPU at 100%

    Hello!

    I have a problem with the java.exe in the environment in which I work. In the environment, I have a physical server: Sun Fire X 4100 Server with 2 processors and 16 GB of RAM for control of virtualization. On the system, this is the Microsoft Windows Server 2008 R2 Datacenter and vCenter 5.5.

    For the most part, we are 5 guys in the team who use the vSphere Web GUI. We are connecting to the server using RDP and after some time, we can not connect because the CPU is at 100%. It takes 20-30 minutes to be able to connect. And then 5-10 minutes to be able to click on something. For example, to kill the java.exe file keeps the CPU at 100%. This isn't a good idea because afterwords the Web GUI does not work so we need to restart the server.

    Anyone of you have any idea why this is happening?

  • Portege R100 - CPU usage 100%

    Hello!

    Everyone knows about this problem?
    My Portege R100 after installing the new copy of Windows XP and directly after the installation of the display driver, Trident (reboot) bizarre behavior.

    Welcome screen goes white on the lower part (when the first yellow line is). Then I have some software problems.

    When to start records search engine, when I update the list of wireless networks and I explore the files by clicking on 'My computer', (this does not happen when I right click on START and 'Explore') displays CPU usage 100% and everything is so slow that I can barely move a cursor.

    Everything goes back to normal once I closed above applications.
    I can install all drivers and all right, but after Trident display it is bad.

    This is the driver I use since I bought the laptop, I do not know that is fine.
    I installed it several times before and I have a few copies of it, which I've already tried so it must be good.

    The cross thing only my mind is a hardware failure.
    Someone of you knows than before?

    Thank you...

    It has nothing to do with your computer - this is the trident driver problem - there is a work - around
    Try changing your display configuration-

    (1) right click on your mouse to the desktop to bring up the display property, and then click Advanced - here, you will see a tab say somethng like 'graphic acceleration.
    (2) reduce the rate of acceleration - move the tab to the left - make sure it is not full
    (3) this trident driver can cause the BONE to redraw the screen whenever you move your mouse with some applications

    If my post is not detail for you
    Try google with the keyword "how to turn off the graphics acceleration in windows xp" - you will get some good instructions

    That will solve your problem!

    Good luck and enjoy your nice laptop!

  • Sampling runs CPU at 100%

    I use a NI 4472 DSA and have a minor problem when executing the example the spectrum analyzer code. Pegs the CPU to 100% when I taste > 25 k. y at - it a known solution for this problem?

    Hi talltubatom,

    The behavior you're seeing is the nature of the DAQmx driver. Ce KB explains this behavior for 7.4 of DAQmx and superior.  If you are looking to reduce the use of CPU, you can use the mode 'waiting', otherwise, if you use 'return', you will still see high CPU usage, but if you need other programs to run, they will see the necessary CPU.  Let me know if you have any other questions on this, have a great day!

Maybe you are looking for
