95% CPU usage and 95% System Idle Usage?

Question: 95% CPU usage and 95% System Idle Usage?

This has been happening for over 2 months now, It happens around every 3 hours for about 20 mins each time, but it gets really ANNOYING. My friends said that I was lying and stuff so I invited one of them over and he saw it happen and he was stumped.

Here's a screeny:


Anyone got any advice?

Preferred Solution: 95% CPU usage and 95% System Idle Usage?

I recommend downloading and running Reimage. It's a computer repair tool that has been proven to identify and fix many Windows problems with a high level of success.

I've used it in the past to identify and fix everything from blue screens (BSOD's), ActiveX errors, corrupt files and processes, dll/exe/sys errors, recover lost memory, Windows update problems, defragging, malware removal etc.

You can download it direct from this link http://downloadreimage.com/download.php. (This link will automatically start a download of Reimage that you can save to your computer.)

Answer: 95% CPU usage and 95% System Idle Usage?

There are times when task manager will misrepresent the total processor usage as well over 100% constantly. This is usually caused by one of three things :
1.Bad DriversMalware on the system
2.A Flaky Windows install - was this an upgrade or an old OS install?
3.A Problem with the motherboard (try a firmware update)

So on Saturday of last week my PC started to run slow. I open up task manager to check what was going on and I am greeted with it showing me that I have very high CPU usage, and constant capped-out disk usage.
Over the course of the past few days I have reinstalled Windows 10, updated drivers, completely formatted my previous hard-drive, and just today I received a new SSD. However, my problem STILL persists, and I'm all out of ideas on what I need to in order to solve this.

My Motherboard is an ASUS Z97-P with an Intel i5-4690K processor. If you need more specifications, or a program to be run, then I would be happy to do so.

For further information, the system ran normally when booting from a Windows 8.1 hard-drive, and did have a blip of normal performance on Windows 10, but resumed misbehaving when the computer was re-started.

Answer:Constant 100% Disk Usage, 60-80% CPU usage. Both happen when idle.

in Task Manager sort by CPU usage and see what apps are responsible.

My computer is running slow 90% of the time. When I go into task manager it says that CPU usage is between 80% to 100% at all times even when im not using the computer. One day it works perfectly and for the next week I can barely even use it. Before I take it to a technician I was wondering if there was anything else I could try.

Things I have tried...

Updated all drivers on my computer
Used windows update to get all system updates
Used Msconfig and disabled all startup items. restarted and still slow.
Virus scans
Defrag
system cleanup
I even formated the computer once. It still crawls.

If there is anything you can think of or if you know what the problem is please please write back. This is unbearable and frustrating cause I cant figure it out. I would assume it was a motherboard or cpu problem but then the computer works perfectly for a few days. Thank you for reading.

Hey guys, I was wondering if this amount of RAM usage was normal, for just idling after startup:

http://i47.photobucket.com/albums/f1...terStartup.png

To me, this seems pretty high and it can go anywhere between what you see here and 1.70GB at times! I notice many systems on here through screenshots being at or well under 1GB for just idling and not doing anything directly after startup, except for mine. I realize my notebook is a multi-touch touchscreen paired with a mutli-gesture mouse pad gizmo and that both must demand more system resources on account of these features than the standard would, but I don?t think those alone should be eating up that much of my RAM.

With that said, how to I pinpoint what is eating all of my RAM and what can I do to get this figure down under 1GB for system idle?

Before we go on let me address this first and foremost, I have NOT messed with startup threads/programs yet because I just don?t know what they are, what they do and if they HAVE to be ran directly at startup or not for the system to run. If you can help me through this as well I would be very grateful and will screenshot what you need to see in order to tell me what to get rid of and what to keep, if necessary.

Currently, this is not interfering with any of my computing tasks, but to be perfectly frank it scares me that my RAM skyrockets to a solid 3GB load doing nothing but playing simple flashgames in Furefox! Same thing for Sims 2 and Sims 3 ? that def... Read more

Answer:Idle System RAM/CPU Usage

Hi,
I would like to see the Processors tab in task manager for starters.
It shows you have 87 processes going on after 5 min into your startup.
That is alot of garbage running in the background.
1.Do you have anything in your startup menu?
2. Could it be Media Center updating it database?
3. What virus protection do you have? Do you have it set to scan on bootup?

Here is a picture of mine to show you what my CPU and 2GB of memory is going right now.

Hello,

First, this is not spyware. I have run every cleaner known to man, and followed advise on the hijackthis forum when i thought this was a spyware problem. MY COMPUTER IS CLEAN.

What is happening is, looking at the task manager the system idle process will be at 98-99%, which means there should only be 1-2% left at idle for other processes, but the CPU usage jumps and varies from 20-40%, while the system idle process is at 99%. Weird.

I ran memtest86, and it is not a memory problem. I am wondering if i have a conflict with my IRQ's? Could this be eating up my processor in the background? Here are my conflicts:

Answer:System idle 99% with 20-40 CPU Usage

I recently had this very same problem. Having a very humble AMD Athlon 1700xp, 256Mb ram system meant that it was very very restricting.

I found the problem to be McAfee's security suite. Likewise Norton Internet Security, in my experience, is extremely system intensive. After removing McAfee everything was back to normal.

Check the processes list in Task Manager. This should also give you an idea about what's causing the problems.

Hello, So I was copying a large group of files (400 gigs) to an external drive, it was about 150 gigs in when the PC crashed ( i believe due to MSI usb speed up), i've since removed the MSI program but CPU usage stays at 100% from the moment the PC turns on, however system idle process shows it's using most everything which is good, and PC perfomance is normal and unlike if CPU usage was actually 100%, but I can't figure out how to fix this, any suggestions or tips would be so helpful, I've attached screen shots showing 100% usage but every program running doesn't add up to near that and system idle showing everything mostly idle. Thanks!!!!!

Answer:CPU usage 100% but system idle process says otherwise

Hello,

I know it sounds a little bit strange, but:

When I open Task manager ->show process from all users, I notice that System Idle is uses about 95% of CPU.
But the overall cpu usage is lower than 20-30%. How is that possible? (windows 7)

Also, I have 2 os installed on the same computer. 7 and XP.
Windows XP 50%CPU load.-> Disable automatic updates=> Low CPU usage.
If I disable auto updating feature in Windows 7 too, and update it "on demand" weekly would that solve the issue?

Thank you in advance.

Answer:High System Idle CPU, but overall, low cpu usage

the easiest way to remove any resource hogs is to:
click start;
type run;
in run type msconfig;
hit enter;
click the startup tab;
untick everything non essential;
personally I untick everything (youd want to keep your virus scanner though)

Though this topic is quite old, I would like to point out that everyone saying 100% CPU system idle process is normal...is CORRECT. With the task manager list, higher numbers could possibly indicate slower functioning. However, system idle process CPU means something different due to its nature, as others have already explained. This does not make sense to some, and I feel compelled to encourage people to ignore the negative voting scores on these entries; and kindly overlook system idle when searching for explanations of slow computers or programs. System Idle Process is not the culprit.

Answer:System Idle Runs At 95-97% Cpu Usage...freezes A Lot

Welcome to BC! Well, I thought I would make a couple of comments here, although I may not have all of your answers for you, and my not have the answers you want to hear!ONE, system idle at 95-97 regularlyThis is a good thing. It means your computer is only using 3-5% of the CPU's resourses. System IDLE is just that, that amount of the system that is IDLE, not working.TWO,256 RAMis painfully too little RAM. Most performance issues start and end here. RAM is so inexpensive these days, even the homeless can afford more RAM! THREE,system freezes regularlyThat is the issue that needs to be addressed. Of course, overclocking your system is going to create a lot of heat, and possibly damage hardware. I know that overclocking your computer is the 'cool' thing to do, but if you really want to enhance the performance of a computer you must first make sure it has enough RAM. This would be number one! Doing otherwise would be like putting a NOS system on your car, even though the car has 4 flat tires! It won't help, and possibly will hurt. Performance in that car would be improved by putting air in the tires first, and I think this is what we are looking at here.But back to the freezing. Heat. Make sure all fans are working. Take the side cover off of your computer and blow out all of the dust, especially on the CPU cooler and the Northbridge cooler (which is usally located just below the CPU). Clean that computer up first, and report... Read more

For some reason the system idle process is showing up in the CPU usage graph in task manager on Windows XP. Which means it always looks to be running at near maximum. So far the only way for me to fix it is to try restarting. Is there any other way?

Answer:System Idle Process showing in CPU usage

It is normal and good for the "System Idle Process" to show high CPU usage. This isn't a real process but more like a placeholder that shows the percentage of unused CPU time.

Alright, you're going to say..."It is suppose to be 100% on System Idle Process, your processor has to be running always so it moves to the System Idle Process."

That isn't the problem. My computer is giving 100% CPU usage on anything possible. It will switch to random programs..which I will end-task, then it will move to another one. It is doing it right now. But, I have end-tasked a lot of programs that it finally immigrated to the System Idle Process. I have a picture to prove to you.

This only happens some times. How I would fix it before..is...Unplug my power cord and let my computer sit for a while..then plug it back in..and it would work some times. But, now I have tried and can't fix it.

Lately, after the fact of this 100% CPU fiasco that started a couple months ago, my computer won't have a POST beep when I start it up. But, if I turn it off, and turn it back on, it will always work on the second time. IT's weird

I have AVG 8 and Spybot Search-and-Destroy, and i do scans with them very often...They either find one or two things...and I clean them up, or I find nothing. Nothing changes this fact.

Not only that, my computer, when it IS working...some-what. (No 100% CPU on random processes) I can't even play Hi-def videos on Youtube or Hulu. I can't even watch movies in 720 P on my computer. And I KNOW my computer is good enough to.

Answer:System Idle process high cpu usage

You want system idle process to be high. That means the processor is looking for work. 99 is better than 60. What is that 22% process--it is running at 0% on my PC.

Sony Vaio VGN-FZ11S LaptopCpu: Intel Core 2 Duo 1.80GHzMemory: 2Gb DDR2 SDRAMGraphics: NVIDIA GeForce 8400M GT GPUWindows Vista Home Premium SP1Norton Protection Centre Antivirus/Spyware/FirewallHello all. QUICK NOTE: Have run a Kasperspy Scan (and have Norton always running) only hours ago and no infection were found so I hope this isn't malware related.After noticing my laptop becoming very unresponsive as of late, I decided to run Process Explorer to find what was eating my CPU. Found out that the "System Idle Process" was fluctuating anywhere between 70% - 90% CPU usage.Now in Process Explorer I then "right-clicked" on the System Idle Process and selected properties and then selected the "threads" tab in the window to find 2 files named the same:ntkmlpa.exe!KiDispatchInterrupt+0x5a4 <-- There are 2 of these showing in the "threads" tab under properties of System Idle Process in Process Explorer.PLEASE NOTE: that the l in ntkm(l)pa is actually a L (Stupid Windows Fonts!)Process explorer will not let me kill the process or restart/shutdown, neither will task manager. Rightly so as I believe System Idle process is vital to the stability of Windows from my research.What I would like to know is, is there anyway of returning this process to using a lower amount of CPU as my laptop is really not functioning as quick as it should be.Also task manager reports to be running 94 processes! Is this normal?Many thanks.Luke

Hi, yesterday I had a very bad lag while I'm playing, it was the 1st time to lag like that, it is not due to connection problem as I'm used to them and they are totally different (this one was with sound interruption).After I finished the game i restarted my pc, the restart took ~35 minutes!
The computer became too slow to be used for anything, I opened the task manager to see what is eating my process to find nothing, System idle process is at 99 usage, even when I run a program or try to play a video it stay over 80, I know system idle process means the computer has nothing important to do, and I think this is the problem.
I'm using windows 7 64 bits. My laptop is acer aspire4720 and there is a small green light which lights when it is precessing, after this problem began it is always green.
I had the same problem in the safe mode.
Opened msconfig but did not find anything new in the startup tab.
There is no new windows updates installed (the latest were before two days and the computer was fine).
No new programs installed, only updated skype.
Any suggestions?
As I'm not sure what is the problem I don't know if the title is correct or not.
Sorry for my bad English, it is not my native language.

Answer:System Idle Process High CPU Usage

Hello L_The_Legend & welcome to TSF

Have you scanned your computer for viruses lately?

Also, tap away at F10 as you start the PC to enter the BIOS menu. Under the Advanced or Diagnostic tab you should find the facility to run a test on the Hard Drive and Memory - run both test and post back with the results. Is the system overheating?

HDD usages reduces life and uses power, its defenitly I dont want to see on my laptop. Am I right this is MSE, and why is it doing a scan everytime its idle? can I disable idle scanning?

scheduled scan is sunday 2am, today isnt sunday and its not 2am.

In addition if I run a quick scan its done in a minute, this hdd thrashing will go on for hours but then stops when I move the mouse pointer.

On my main desktop its more an annoyance than a big problem but I want to get the bottom of it.

My hdd light flickers roughly every second doing something, resource monitor shows the 'system' process. It does it even when no foreground apps opened at bootup.

Background apps are.

Logitech game profiler.
7 taskbar tweaker
nod32
pidgin
windows 7 firewall control
dumeter
proximitron

and usual system services

there is more background apps which I start after bootup but they excluded as it happens before I start them. My 2 chief suspects are du meter since I think it logs usage frequently and windows 7 firewall control which I believe polls the windows firewall log. If I hammer the windows key on this system so the menu comes on and off it generates hdd activity as if nothing is cached, my laptop doesnt do such a thing, this desktop has 16 gig of ram as well.

so 2 problems in one post.

Answer:msmpeng thrashing hdd when idle, also on a 2nd system hdd usage

For the msmpeng issue, try a clean boot via msconfig. If the issue goes away, it indicates a conflict with one of the programs/services you disabled.

As far as the desktop machine is concerned, how long has this HD activity been going on? You can open Resource Monitor to see what's being read/written to.

So, I just updated from windows Vista Ultimate 32bit to 64bit. I also upgraded my memory recently from 2gb to 4gb though i don't see how that would factor into this issue considering the ram is perfectly capable for my motherboard.

The issue is I'm seeing huge spikes in my system idle process. My computer will go from nominal performance to around 50-100% usage. My cursor lags and trying to navigate menus is impossible. The really annoying thing is that it was running alright yesterday but today it's kicked off my internet (it was working) and now it's practically unresponsive. I've scrolled through similar topics concerning vista 64bit but i haven't seen any other person's issue that looked similar to mine.

I've tried updating my drivers using a memory stick, downloading the chipset, graphics card, sound, and various other drivers on my laptop and then installing them on my desktop since i can't get the thing on the internet, but to no avail. My onboard lan refuses to connect to even my modem hooked-up directly, much less through my router. Sometimes it will act like it's at least connected to the router but i cant get to the router configuration utility through 192.168.1.1 (it's a linksys router) which makes me think that the drivers i used to update the motherboard LAN weren't compatible with vista64 even though the site i downloaded them from the marvel yukon site saying that they were compatible with vista64.

Hi,
Its my first post here. Greetings to everybody.


I run a Windows XP SP3 based system with all updates and latest drivers installed, and the software maintained for optimal performance (stuff like a clean and defragged registry, defragged file system, minimal background processes and disabling of non-essential windows services, no malware/spyware, absence of junk files, etc etc). The hardware config consists of an Core2Duo E6750 CPU, Corsair XMS2 2GB memory, Gigabyte X-38 DS5 motherboard, Gigabyte 8800GT based GPU and a Seagate 320GB HDD.

Since a past few days, I've been noticing abnormally high CPU usage under idle conditions. The processes "System Idle Process" and "System" occupy anywhere from 40% to 70% CPU usage. I have the Enhanced Halt (C1E), Thermal monitor 2 and Enhanced Intel Speedstep Technology enabled in the BIOS - in case this information is relevant. Hardware Interrupts, Deferred Procedure Calls under System Idle Process seem to take up cpu cycles for most of the time, possibly indicating a driver bug. I have not installed/removed any software, hardware, nor updated any device drivers which would lead to such a problem suddenly. Normal workloads are not affected, however stuff like playing video with PowerDVD 10 and running the Milkdrop Visualization are badly throttled.

Please Advice.

Answer:Abnormally high CPU usage by System Idle Process

I'll think on your problem for a while, but I wanted to comment that Milkdrop is the best visualization software ever, and it can definitely take its toll on any processor or gfx card lol. Are any of your processes using more resources than normal? It would appear you have a firm grasp on what is usually running on your system, so is anything out of the ordinary?

Ideally though, the "System Idle process" should be as high as possible, as that is where your excess cycles are going. So, the higher the number, the less resources your usual operations are using (so 99% idle process means 1% in use) (Also, that is my understanding of it, if I am incorrect in this assumption, somebody please correct me, I have not really ever thought about that process before).

I don't think your bios settings will interfere with that, but I could be wrong, again somebody correct me if I am wrong (making another assumption).

Are you using a laptop? Sometimes slower processing can mean the battery is going bad (Though not always)

Try running some form of monitor to find out if your processor is running up to par (cpu-z works alright for quick checks). But I think it is probably something else. Gfx card going bad or underclocked perhaps?

I am not really sure what could be causing it, you seem to sound like you already checked for abnormally running processes, so I am at a bit of a loss. Perhaps it could be hard drive slowing down or something? I am sure MoM will come in here and cor... Read more

Guys I need some guidance hunting the cause of high System Interrupts level on a freshly-installed notebook. This is a hp g4-1117dx, with amd llano/hudson, A4-3300m, 4gb, crucial ssd, etc. no external devices used at all.

at idle i have an unacceptably high level of system interrupts, around ~30% cpu utilization. I've checked drivers carefully, but as you know, just because its recent and sourced right is no guarantee of success :cry
I've tried disabling all USB hubs via Device Manager, no change whatsoever.
tried disabling and uninstalling WIFI, NIC, GPU... none of that had any noticable effect. tried uninstalling and reinstalling the IDT audio device. no effect.

I have never used Process Explorer 'til now so I dont' know what I'm doing with it. it shows the general problem but drilling down I can't find the item that is sourcing this flurry - but then I have no idea how to do so properly. I read about xperf but it looks more complicated. I have pretty decent skills so not afraid to give it a go but wanted some advice

Hey all. So I upgraded to 8.1 from 7 and I faced this issue where I have the same exact programs opened that I had back on windows 7, but now they are generating alot more CPU usage. I can't find any solution to this, other than installing 7. That fixes
it. On win 7 with the same exact enviroment (same programs opened, same page on google chrome opened, same exact everything) I get 1-4% cpu usage which is great. On win 8.1 however, with again everything the same, I get 18-30% cpu usage.
And it's all caused by windows' processes and stuff. Can't really shut them down because things won't work then.
I kinda like win 8.1 so I don't wanna go back to 7, but since my performance is crippled, I might have to. Any suggestions are much appreciated! I've tried some things that I found on the internet, but nothing seems to fix it.

A friend of mine has the same mobo and cpu as me, but when I did a test and created the same exact enviroment as on my pc, the usage doesn't go above 5% when idle.
I dunno what to do at this point.
Here's some screenshots of my task manager:

So I have a fresh install of Win8.1 LEGAL copy (it's about 2 weeks old)

I noticed yesterday abnormally high CPU usage. ~40% in task manager when the computer is doing nothing.

After some investigation, most google searches are telling me it's a driver issue, run a trace this or that. It looks like the process is simply "SYSTEM".

Okay -- so a few more details. When I do a fresh reboot, the issue doesn't exist. Super low CPU usage 1 to 3%. Wifi works, everything is working as it should. If I don't do anything, i.e just let it sit for 5 to 10 minutes, CPU usage will spike to 70%, soon as I move the mouse it will fall down to 50% then to 40's. Another byproduct of this problem, is when I do a restart or shutdown, it will go to the restart screen with the rotating circle thing and sit there, not a hard crash, but will just sit there spinning forever. (I'm forced to do a hard reboot). This issue does NOT happen if I reboot in the first few minutes of starting windows, before this unknown process/thread takes root. Did a full virus scan, and malwear scan, even uninstalled Acronis.

I've disabled my wifi adapter, all the normal programs I use (dropbox, evernote, afterburner). Just reinstalled the latest video drivers.

Still confused as to why this is going on. I've used process explorer to poke around but still can't get to the root of what's causing it. There doesn't seem to be detailed instructions I could find... Read more

Hi there,
as the titles says, i am having an unusually high usage of cpu from those 2 processes (25-80%) on my quad core 4.3 Ghz processor,which i highly doubt is normal. another weird thing i noticed is that it's periodic, meaning it would be very high during the day, but during the night it's fine! i am afraid my device has been infected with a bitcoin miner or something!

Okay, this is driving me crazy. Whenever my PC is left idle for some time, CPU usage by "System" will ramp up. I have no idea what is causing it. I had thought that there was something in Task Scheduler that would run itself whenever my system was left alone, but there is nothing of the sort. I've also tried using Process Explorer to get a more in-depth look at what the heck "System" is, but it's as equally vague as what Task Manager is telling me.

About a year ago, I noticed that my computer was running slow (both online and off) and that the explorer.exe process listed in the Windows Task Manager was usually running very high. Windows Explorer seemed to crash a lot as well. A few months ago, I attempted to install Kaspersky Internet Security 7.0 on my computer and before the install completed a warning window popped up saying something like 'there is already another instance of Kaspersky running' (which was not the case since this was the first time I had ever attempted to install Kaspersky software) and the install failed. When I rebooted my computer, I got the blue screen of death for a few seconds and then Windows booted with a message saying that Windows had recovered from a serious problem. Since recovering from whatever happened after the failed Kaspersky install, my computer is slower than ever and the Task Manager still shows a high CPU usage even though the System Idle Process is high and there isn't any processes listed that are using much CPU time at all.

I just scanned my system with the latest updated versions of AdAware, Spybot S&D, SuperAntiSpyware, and Avira AntiVir. All of them found nothing. I then cleaned my computer with CCleaner and ran HijackThis.

So I've been working on my friend's computer for a couple of days now. She had been running a virus scan using AVG because the computer wouldn't let her get online and was running very slow. It found some infections and went to quarantine them when her computer froze. On a reboot, she got a blue screen about a Fatal Error.

I was able to get the computer into Safe Mode and then running again using the most recent configuration that worked. The CPU usage is still at 100% with no programs running are aoltsmon.exe (AOL top speed monitor), csrss.exe, and winlogon.exe. I set the priority of them all to low and the AOL executable was no longer a problem. The other two continued using about 50% of the CPU. After doing some reading, I found that some viruses disguise themselves as these executables. The blue screen was most likely due to AVG deleting one of them, right? Is it possible that these are not caused by viruses and is there any other way I can make them stop being such resource hogs? Unfortunately I didn't think to copy over the Hijackthis Log, but will the next time I have access to the computer if needed. Thanks for reading

This is not an issue but more a curiosity. I have the old Windows cup / ram monitor running as a gadget on Windows 10. When the PC is idle for a few minutes I notice the cup usage always spikes to around 10-13% and stays around that mark. As soon as I touch mouse and move it it then plummets to 0 or 1%. Is this normal? I wonder what it could be doing. It's not as if I can use task manager to see because as soon as I move the mouse or go to use the PC the usage returns to 0 or 1? I presume Windows is doing housekeeping stuff and it's a non issue?

cheers, Wayne

Answer:CPU usage when PC is idle

Ok, I left task manager open and waited for a few mins in front of computer not touching anything. The service that starts up is system and compressed memory. It's always about 13% and seems constant when machine isn't in use. Like I say, as soon as I touch the mouse and move it the service reduces to 0. The actual memory amount this service consumes is only about 50 mb.

UPDATE - so I left it idle quite a while, about 20-25 minutes. Long enough for my screensaver to kick in. Of course when I touched the mouse to resume desktop cpu usage was at 0. What was interesting is I looked at c: drive (SSD) which had consistently been 247 Gb free but it had risen to 252 gb. And when I left the machine idle again for about ten mins the cpu usage stayed at 0. So maybe whatever the system was doing got enough idle time to finish. It'll be interesting to see after shutdown tonight whether this cpu usage rises again when I switch on again tomorrow - am hoping not. I guess it's similar to what I saw on Windows 7 (still faithfully on my older laptop) where I would notice the available free space, on occasions, fluctuate (mainly rising) after a decent amount of idle time. I'm not one to leave my machine on for prolonged periods when not using it and as the Windows 10 desktop is newish and I'm almost always doing stuff/installing stuff at the moment to bring it to similar functionality to my other laptop (mainly games) it gets very little idle time for more than a few minutes at most.

Before i give up and just delete this process all together, I thought I would ask people who actually knew what they were doing.
My CPU usage is constantly between 60-100% (almost always 100%) even when I'm doing nothing. In Processes, ftgrrifc.exe from AppData-Roaming takes up 40-50% of my CPU usage. Also, System Idle Process can jump anywhere from very low to near 50%. Skype.exe can also jump from nothing to 50% for a few seconds.
I would like my laptop to go to the good old days where i could actually play games/videos on my laptop. I am the only user on the laptop.
Microsoft Security Essentials says the laptop is clean, and Malwarebytes says I have no malware.

my dad's computer has 80%-90% cpu usage while idle.

in task manager, the process using the cpu is not there, so I had to run process explorer.

There's 2 processes using all the juice: Hardware Interrupts and Deferred Procedure Calls.

Everything's fine in safe mode, though.

anyone knows what's going on?
 

Answer:cpu usage at 80% when idle

Many things run in the background in Windows 7. Your Task Manager can tell you, but it's probably nothing to be concerned with.

Question: CPU Idle usage

My CPU usage when it is in idle stay between 5% and 10% most part of the time...with some peaks of 20% some times(NOT really often at all)...

Is it normal? I have many svchost running background...I dont know if I can disable than...anyway...

My CPU is an core 2 duo E7500 at 2,9Ghz
One more question: I bought GTA IV and it drains very much from CPU(benchmark say 98% of CPU usage)...in msconfig, in the part of services, can I disable than all? One guy told me that I can and after doing to reboot...than the windows will only iniciate the services needed for the functioning of the PC...than when I start some task that need a service that was disabled this one will start again...is it true?
Thx!

Answer:CPU Idle usage

Hi there.....

dont disable all services... , just leave them if your not sure about it, there's a few links on the web which will help you ascertain which services you require & those you dont

here's one of them

in regards to CPU usage, head over to ''task manager'' via (ctrl/alt/delete), when the window opens select ''processes'' here you'll see what apps are currently running & the amount of CPU power is being used.

you could post a screenshot of the processes box here & we'll see if anything looks abnormal...

GTA4 is a rescource hog....its that simple.

top end machine still struggle with this game, & its pretty poorly coded for the PC.

looking at your specs, as long as you can play with some degree of fluidity & your not getting 10-15fps (like a lot of ppl do), then i'd be happy

Question: CPU usage in idle

Hello,
I have question regarding CPU usage when my laptop has not have any application up and running (at least not by my request).
I have changed some of the Start Up in msconfig. Everything that I don't really need on immediate Windows start up I have not selected. That is fine.
But still absolutely randomly I will have my CPU usage going up and down from 1% to sometimes over 40% if not even more. Recently what has happened is that I left task Manager up (only, nothing else) in order to monitor CPU usage. While I was watching CPU usage was as I would say normal. 0%-7% up and down. After let say 45 minutes I got back to check again. I log on and much to my surprise I have noticed that my CPU usage in last, at least 10 minutes was constantly around 40%-50%. Strangely enough few second after I log on CPU usage has dropped down to the previous percentage.
I am talking over here about Acer 5378Z
4GB RAM
T4300 Dual Core
WD320GB 5400
Intel Graph (up to 1.8GB share memory)
Windows 7 x64 Home Premium (with latest updates)

Do you have any idea what it could be?
I also scanned computer against viruses and malware. All clear.

My Laptop was never run into this problem. My laptop (axioo PICO DJV) is became REALLY slow and laggy this very day. When i open the taskmgr it always said that the CPU Usage is 100%, even when windows is idle at the desktop with no any program running. I've tried many repairing utility (cleanmgr, defrag, uninstalling rubbish programs, readyboost, even System Restore) and none of them worked. The processor became really hot and always at the limit spot of 1,666 GHz, even when the windows is idle. Is there any way to fix it? since I can't use my laptop now because all programs will gone not responding. (sorry about my bad english, I didn't knew much)

Question: CPU usage at idle

I'm having an unknown issue with a computer...when idling, with no background services or programs running, it jumps between 40-60% CPU usage in the task manager Performance tab. Under Processes, System Idle Process is at 99%, with nothing else showing up that isn't part of the operating system. In normal use, it acts like its doing something else so I'm betting the Performance tab is more correct than the Processes one. Scanned for viruses and ad/spyware with nothing showing up. Anyone know of anything else to try?

The processor queue is a bit higher than it should be at 2-3 nonstop, never dropping below 2

The system is a Duron 1GHz with 768MB ram, external video, sound, etc on WXP Pro/latest SP and hotfixes

This has to do most likely with the DPC Time Placeholder, or Interupts Time Placeholder.

Hey folks, I need your help troubleshooting here.

This is with a clean install of 8.1 from a MS ISO, downloaded and installed on Nov 14th. It is fully up to date.
This behaviour was not present with Windows 8, but I have done 3 clean 8.1 installs with the same outcome.

When I first power on my laptop, after windows is loaded, Core 0 on my CPU (i7 4700MQ) idles at around 90%, with task manager showing 11-15% CPU usage. System interrupts shows the most usage of all items on the list.

I have changed the minimum usage in power options to 5% for all power profiles. This behaviour is present under low power, balanced, and high performance power modes and doesn't change if I change them. (See Windows 8 task manager and 4th gen i7 ). In low power mode the usage is slightly less but is still present.

This processor usage continues as I run other programs, or as long as I let it idle without going to sleep.

If I put my computer to sleep, and then wake it, after idling for a short while..
all is as it should be!

I have the latest drivers for my chipset, GPU, WiFi, and Intel graphics (laptop has switchable graphics). This behaviour is present even with the OEM 8.1 drivers for these items.
All my other drivers are the ones released by my laptop OEM (Sager) in the last couple of weeks, specifically for 8.1.

This is not an issue but more a curiosity. I have the old Windows cup / ram monitor running as a gadget on Windows 10. When the PC is idle for a few minutes I notice the cup usage always spikes to around 10-13% and stays around that mark. As soon as I touch mouse and move it it then plummets to 0 or 1%. Is this normal? I wonder what it could be doing. It's not as if I can use task manager to see because as soon as I move the mouse or go to use the PC the usage returns to 0 or 1? I presume Windows is doing housekeeping stuff and it's a non issue?

cheers, Wayne

Answer:CPU usage when PC is idle

Ok, I left task manager open and waited for a few mins in front of computer not touching anything. The service that starts up is system and compressed memory. It's always about 13% and seems constant when machine isn't in use. Like I say, as soon as I touch the mouse and move it the service reduces to 0. The actual memory amount this service consumes is only about 50 mb.

UPDATE - so I left it idle quite a while, about 20-25 minutes. Long enough for my screensaver to kick in. Of course when I touched the mouse to resume desktop cpu usage was at 0. What was interesting is I looked at c: drive (SSD) which had consistently been 247 Gb free but it had risen to 252 gb. And when I left the machine idle again for about ten mins the cpu usage stayed at 0. So maybe whatever the system was doing got enough idle time to finish. It'll be interesting to see after shutdown tonight whether this cpu usage rises again when I switch on again tomorrow - am hoping not. I guess it's similar to what I saw on Windows 7 (still faithfully on my older laptop) where I would notice the available free space, on occasions, fluctuate (mainly rising) after a decent amount of idle time. I'm not one to leave my machine on for prolonged periods when not using it and as the Windows 10 desktop is newish and I'm almost always doing stuff/installing stuff at the moment to bring it to similar functionality to my other laptop (mainly games) it gets very little idle time for more than a few minutes at most.

Hi
My Win 7 Acer RAM (3GB) is running at 46% idle? This seems to be alot?
Though it does not increase that much with windows open, even when I open WMP and play music it only goes up to 49-50%.
I use the gadget on screen and double check it with task manager, they are the same.
This is more than the previous Vista Basic machine, which I returned, it ran at 40%?
Is there a way to adjust or sort this?

Oh, this morning it went up 99% and I could not switch it off, I had to hold the button to switch off?

Any help.
Thanks.
Neil

Answer:Win 7 RAM usage at 46% idle?

Open Task Manager > Processes tab > click on "Memory". There you will see which processes eat your RAM - ordered by size. Maybe you have too many startup programs. Have a look in msconfig and disable those that you do not need (which are probably all). On the other hand, there is nothing wrong with the system using all the RAM. I assume it's all paid for - LOL.
But when you have excessive usage (like the 99%), you can also kill the culprit process in task manager. No need to shut off the whole system.

My CPU usage hovers between 25-30% without any programs (except explorer) running. This is causing my sound, CD playback as well as any other media etc. to skip/stall dramatically.

Nothing found by AVG except to note a change in the MBR?, though Spybot and Ad-Aware both discovered and eliminated 'threats'. As suggested in this forum under another thread, I tried unsuccessfully to install Livecare, but it errors out when trying to uninstall dotnet2.0. The 'Processes' tab under task manager is apparently no help as it shows 'system idle' at 99% at the same time the CPU usage is at 25% under the 'performance' tab.

I have an AMD Quad 965BE, and i've noticed that when the computer is idle and i'm not using it, the CPU fan speeds up a great deal due to heavy CPU usage. I'm wondering if this is due to some service running in the background on Win 7 64-bit only during idle periods. It's a clean install so it shouldn't be anything i've loaded on that is doing it.While i'm using it, my CPU runs at about 86F and the CPU fan is inaudible. But when i'm away from the computer for a while, I can hear the CPU fan making a lot more noise due to being higher RPMs. When I get back on the computer, I check the temp immediately and it shows 105F. But immediately after I start using the computer again, the CPU load dies down, the temp cools, and the fan speed slows down again.I don't like this because the stock fan makes a noisy whine at high RPMs and I also don't like the thought of my computer running overtime when i'm not using it. Anyone know what the culprit could be?

Firstly, I'd like to say hi. After reading many posts (and finding many solutions to my vista questions) I now have a question/possible problem.

At idle, I have 50% cpu usage at times. It seems to be msiexec.exe. I have absolutely no idea why. Is this a normal Vista behaviour?

Second, at startup I have 67 processes running, then it jumps to 72, then back down to 67. I had this amount on my XP pro machine, but had probably over 60 different programs installed, as it was a shared machine with CAD programs, graphic design software, etc. Now I only have vista, adobe cs3, blackberry, and office...

And for my final question, Why does eSata not able to "hot-swap"? Is this normal as well (sorry, I've always used firewire for my external drives, but now I'm trying to use eSata)

Why would the Microsoft Installer Component be constantly active on your system? That should only be active when you're trying to install a new program, so obviously something is trying to install on your computer that you don't have any idea about.

If not, then vista also defrags constantly when idle so you don't have to run the defrag program. You might want to see if disabling the auto defragmentation helps any.

Answer:High RAM usage while idle

You might also want to post a screenshot of your start ups.

Cortana seems to be using a lot of memory for just being idle. If this is not being used, perhaps you might want to disable that. Your CPU also seems high for just being idle. I don't know if this 'jumped' while you took the screen image, but to me it appears that in these three images, your CPU load ranged between 15 - 36%, which seems high for your processor during basically idle time. You might want to boot into SafeMode and see what things look like. See HERE.

I would think you should see a noticeable drop in resource usage while in SafeMode. If that is the case, then it might be some software conflict.

You might have to disable one start up at a time, then test your system. If no change, go back and enable it, then disable the next one in line.

You might also be experiencing some memory leak some place, that might be the cause. However, you would have to identify which program or application. If you recently installed something just before the problem began, that might be a place to begin.

There is something that might help, at least until you get this sorted out. There's a free program called CleanMem.

I have used it for years, and I do have it on my Win-10 machine as well, although it does not indicate that it's compatible with win-10 (yet).

It will force the release of unused memory every 'X' amount of time. It's defaulted to every 15 minutes, but I have mine set for every five minutes. When... Read more

Hey,

I have had this problem for a long time.
When I turn my computer on, I have to be lucky that it isn't in 50% CPU Usage mode. Most of the times when I turn my computer on the cpu usage is showing 50% on idle. Everything is lag, even surfing on the internet. And then I have to be lucky and restart my computer to make it normal again, to 0% CPU usage, I have reinstalled windows like 3 times, same result.
I can't remember anymore what programe I started, but it has the name explorer in it, it said that it was hardware interrupts that is causing the 50% cpu usage, but nothing more.


Here are my systemspecs:


Processor: Intel Pentium 4 3.2 Ghz Northwood 478 Socket.
Motherboard : MSI MS-7042.
Videocard : ASUS V9999TD, also known as nvidia 6800.
Ram: 1 GB PC2700 333 Mhz Ram.
HD: Seagate 7200 RPM 200 GB.
Soundcard : Soundblaster Audigy 4.


Thanks.

Hi guys,
When I open Windows Task Manager the numbers in CPU never seem to add up to the 50% that it says it's being using, so I'm not sure what process is hogging it. Once I open Chrome, it can go up to 80-90%.
Also when I'm in chrome and I enter an url it seems to take longer than usual and even not going to the address just staying in the blank page.
 
I got told that I should include screenshots from both task manager and process explorer.
 
PS: I'm a new user but I'm a bit tech savy and my most fear is that it is the beginning of hard disk failure.

Hello Crew!!! I have been using a ThinkPad Z60t, running the OS WinXP Pro that came bundled with the Thinkvantage Software. I have had no problems with my computer for the two years I have been using it. I use it as much if not more then a traditional desktop, covering all aspects of my life, from business to gaming (although it is not a gaming comp, it does me fine). Recently, within the last week or so, I noticed a huge lag-like spike every minute or less, including when the system is idle and isn't playing anything. I ran McAfee as well as AdAware and found no issues out of the ordinary. After reading a few forumn posts, on other websites, I ran a processes check, with Microsoft based software "Sysinternals" and found that over 50-80% of my processor was being used by Deffered Procedure Calls (DPC's) and Hardware interrupts. I chose to reinitialize my entire system, back to factory settings, wiped it all. Guess what it is still doing it!!!!   I have completely updated my OS, and other forumns suggest that there is a hardware issue, or intermittent signal with the CPU or Motherboard, what can I do to test this theory or to find solutions, please help me!!!!!

Answer:cpu usage high at idle

Easiest way to ID the culprit is to start the taskmanager and look down the list of services, a lot of open office progs seem to do this and other GNU licensed stuff, seems not to be as good as proclaimed, but taskmanager should soon tell you the culprit.

Hi all, have this problem for a while now. I have 16GB of ram and usage is extremely high while PC is in idle. 99% ram usage and 70-80% quite often.When i start the computer it's fine and then it starts slowly to increase to as i said 70-80 and finally 99%. Computer doesn't lag or lacks of performance even when 99% of the ram is used ?! If you know how to fix that s..t pls aa and that happens in win 10 and win 7 also
I checked task manager to see which process uses that much memory but nothing appeared to be out of order. Could it be some kind of virus ?

Hi

I have an issue with my CPU where CPU1 will stay at 60-100 % work rate when idle, and CPU2 is staying at around 20-60%. The rest are staying low at around 0-10% with a few minor spikes here and there.

I have unparked all my cores to try and get the latter ones to take some of the work away from number 1 and 2, but it doesn't seem to help much. I'm wondering what could be causing this. Im gonna give you a picture showing how this doesnt add up from my point of view, and i'll write my specs down.

Fyi my main problem is when i try to run games like Arma 3 (which has pretty horrible single threaded CPU usage as i understand it) and it doesnt have any juice to work with as it's only using my already overworked CPU1 and maybe a bit of CPU2.

Another odd thing to note is that the game runs smooth sometimes, and other times the FPS is so low when i enter the game and throughout the game that it's basically unplayable.

Specs:
- Intel Core i7-2600K CPU @3.40GHz
- 16 GB ram, 1600mhz
- 2x AMD Radeon HD 6900 crossfired
- 800W Cooler Master silent pro gold

Answer:High (idle) CPU usage

First....I see you are using MSI afterburner, turn that off and see what happens. Next...I see you have and AMD 6900 series GPU and you're running the Crimson driver package for it (is that the BETA driver)....not possible as those 4xxx, 5xxx and 6xxx series GPU have been labeled as Legacy cards and no further support is available and the last known driver for them is the 15.7.1 package. That might be your issue right there.

I'd start off with turning off AfterBurner and then installing the correct GPU driver and then check your results.

Hey guys,

My sister recently noticed a drop in performance from her laptop.
She asked me for help and I tried to fix it but it seems I lack knowledge about the problem.
So here I am asking for help from anyone who might know how to fix this.

When on her laptop I did the following things:
I closed all programs in the taskbar and went to the processes tab.
There I found out about explorer.exe using 20 percent of the cpu.
I searched the internet for a fix for the problem.
I have scanned her computer with Microsoft Security Essentials and also tried CMD sfc scannow.

I ended up using Process Explorer. With that program I managed to kill the explorer.exe thread that uses the 20 percent of the cpu. So while that fixed the problem, every time she restarts the laptop the problem comes back.

So I hope someone can tell me how to permanently fix this without completely reinstalling Windows.
Thanks.

IN recent weeks I have commenced experiencing what appears to be a "hogging" of my resources. It first manifested itself during typing of simple email messages. One or 2 lines of type on the monitor screen would follow in sync with the keyboard and then, suddenly, the cursor would stop even though I continued to type. Sometimes it would approach as much as a minute before it would catch up to where I was on the keyboard. I also noted these interruptions in scrolling, in backspacing, etc. Today I was in Task Manager and noted that there were 51 processes listed and even though no programs were running the CPU usage indicator for one of the processes, "System Idle Process", was jumping back and forth between 00 and 100% (all the others were holding steady at 00 or thereabouts). I am networked (2 computers) with a router and builtin firewall. I'm also using Norton Anti-Virus and Zone Alarm Pro. Frequent scans for viruses show up nothing. I also frequently run Spybot & Destroy, Spy Sweeper, and Ad-Aware. So I don't believe it's a result of hacking. What else could it be? Can someone tell me what the "System Idle Process" represents and what kind of readings should it be showing when nothing is running? I have a fairly fast processor (1.5 Gb), 256 MB Ram, and am running XP Pro.

Hello Everyone,

Firstly, please forgive me if any of the below requests are ignorant, I am new to the world of troubleshooting Windows 7 this thoroughly.

Overview:

I have had a perpetual issue with CPU Usage and have tried several different methods of eradicating the issue without much success. After a lot of trial and error I do believe the issue lies with open services/processes that I am not confident of disabling. Could someone please help me understand or locate the resource hog.

Specs:

I currently have a new system: AS ROCK Z77 OC Formula Motherboard, Intel Core i7-3770 Ivy Bridge, 2 x Velociraptor 10000 RPM HDDs, 1 x Seagate 1TB 5400 RPM HDD, 1 x 160GB Seagate 5400 RPM HDD, 16GB DDR3 RAM, Nvidia GTX 670 GPU (4GB Version).

Core Issue:

When I first installed Windows my CPU usage was 0 at idle, now its 15%-25% at idle, and I can’t seem to find out why. Some may say around 20% isn't that bad but this is how it started with my previous system and then towards the end i had it at 90%+ and i had NO way to resolve that, so i want to address this problem before it gets out of hand.

CoreTemp manifests the following:

Core 0: 46-49C
Core 1: 49-53C
Core 2: 46-49C
Core 3: 43-46C

Processes:

I have 83 processes running and my memory usage is 2.46GB.

Here are screenshots of my Process view:




I have no viruses detected and either way my PC is hardly 3 days old.

Hello.

I have been having this issue for a bit of time now actually. My PC used to run between 0% and 5% idle, and it still does until it's finished loading everything from boot. It's almost as if there's some software running in the background or something that I can't see, because all programs shown in the Task Manager show 0% usage.

I recently cleaned out my PC and re-applied thermal paste to the CPU, and there was no change. I also did a ton of malware scans and such yesterday with Malwarebytes, RogueKiller, Eset online scanner, and Adware Clean. RogueKiller found a couple of PUP's and Adware Clean found a couple too, and they were removed. No change from that either.

So now I am stumped. As far as I know, it simply looks like nothing is making my CPU do that, but that can't be. There must be something going on, but I surely haven't a clue. Can anyone suggest something?

Answer:High RAM usage while idle

You might also want to post a screenshot of your start ups.

Cortana seems to be using a lot of memory for just being idle. If this is not being used, perhaps you might want to disable that. Your CPU also seems high for just being idle. I don't know if this 'jumped' while you took the screen image, but to me it appears that in these three images, your CPU load ranged between 15 - 36%, which seems high for your processor during basically idle time. You might want to boot into SafeMode and see what things look like. See HERE.

I would think you should see a noticeable drop in resource usage while in SafeMode. If that is the case, then it might be some software conflict.

You might have to disable one start up at a time, then test your system. If no change, go back and enable it, then disable the next one in line.

You might also be experiencing some memory leak some place, that might be the cause. However, you would have to identify which program or application. If you recently installed something just before the problem began, that might be a place to begin.

There is something that might help, at least until you get this sorted out. There's a free program called CleanMem.

I have used it for years, and I do have it on my Win-10 machine as well, although it does not indicate that it's compatible with win-10 (yet).

It will force the release of unused memory every 'X' amount of time. It's defaulted to every 15 minutes, but I have mine set for every five minutes. When... Read more

Hey there. My name is Josh and I hope you guys can help me.

For some reason or another, my computer will randomly slow down and start eating away at my disk and cpu.
I can't pinpoint a particular program that causes it, but I'm usually running Firefox when it happens (I almost always have Firefox open) although it's happened even when Firefox isn't running.
When I check my Task Manger/Resource Monitor it shows a constant 99% CPU usage, but combined the programs only show using up to 3% of the CPU (Not counting System Idle Process of course)
The slowdown stutters back and forth, so sometimes I can move the mouse and click, but then 5 seconds later it's frozen up again.
During this time, Resource Monitor shows spiking Disk usage on my HDD and it's always (when it's there at all) from pagefile.sys.
It has some read I/O activity that's usually below 40,000 B/min, but the write I/O activity can regularly show between 50,000,000 and 100,000,000 B/min.

My memory usage is at 50% when no programs are running. I just downloaded several updates and I'm not sure if that has to do with it, but restarting after the updates was unusual and restarting generally now seems to take longer as if there's a delay in the process of getting to the sign-in screen.

I don't tend to look at my memory usage but I did a month ago in checking my virus scan. During that scan my memory usage was essentially flat at 500 MB or 25%.

Thanks

Added a shot of processes of all users while idle.

About 2.5 hours after posting I closed the installed programs window I was looking at and saw the desktop icons kind of flicker. I checked my memory usage at idle and it was down to 38%.

Restarted, back to 50%.

Answer:Memory Usage 50% at Idle

Sorry that you are having problem, but its easy to check
With system restore go back to pre update times. If memory is usage is back to normal that is the problem.
Now restore the updates one at a time, to find the culprit. Report back and lets see what we can do.
If uninstalling the upadates does not work, report back and we will test the memory and check for other possiblities.

Hi there,
 
I found this forum when my laptop was infected by qvo6, and I've removed that hijacker successfully using the instructions here (http://www.bleepingcomputer.com/virus-removal/remove-qvo6.com-browser-hijacker), thanks very much to all the volunteers!
 
Not sure if I'm being more sensitive to my laptop's changes because of the qvo6 incident, but recently I've found that my CPU usage is always high - at least 50% even when I'm not running any programs.
 
When I open Windows Task Manager the numbers in CPU never add up to 50%, so I'm not sure what process is hogging it. Once I open Chrome, it can go up to 80-90%, which hasn't really happened before (I usually can use Chrome, Firefox, iTunes, Microsoft Word simultaneously without any problems).
 
Would someone be able to help me with this? As mentioned, when my laptop was infected with qvo6, I ran iExplore, adwcleaner, malwarebytes and the scans are clear except for a "##### C:\Users\AppData\Roaming\Mozilla\Firefox\Profiles\XX_clean\prefs.js"
 
Appreciate any advice, thanks in advance!
 
ETA: First time user here, so please let me know if it's not the right forum for this issue.

Please post a screenshot of Task Manager...which reflects this high usage.
