Maintenance :: Windows Task Manager Showing High System Usage?
Jun 10, 2014
My task manager is showing an unusually high CPU usage by the system, anywhere between 20-30% when the computer is idling. I've run the sfc /scannow utility and it found some corruptions, which were then fixed by the DISM utility. However the task manager is still showing that super high CPU usage and no amount of restarts is changing anything. I've attached an image of my task manager.
Lately I have noticed a high disk usage with the computer using task manager. Things that cause this spike is conducting normal operations just as opening an application or the web-browser.
I do not recall seeing any disk usage on task manager for the past few weeks except yesterday (perhaps I did but I do not remember). It appears to me as if those application are using the HDD as RAM even though there is space on the 8GB memory. So I am not entirely sure.
I would like to know if it is normal for applications such as Chrome to be using the disk space? And if so, what may be causing high disk usage?
I bought a new desktop last year to run high-end software used for my degree; I installed Windows 8 on it, having got on with it on my laptop. I did notice though, after venturing into the Task Manager, that my CPU usage was at 100%. All the time. Even when idle. In fact, resource monitor says it's working at 108% load! I thought this was rather odd, so investigated further:
It appears that task manager divides the 100% usage proportionally between the processes using the CPU. So for example if Firefox, Word and Notepad were using 5%, 3% and 2% respectively, Task Manager would report 50%, 30% and 20% usage. I was initially concerned that my processor was going to take some serious damage to its life expectancy if it was being constantly loaded - but the performance monitor in Norton Anti-virus shows the CPU load to be much, much lower - where I'd expect it to be.
My system is an 3.4GHz i7, with 16GB RAM running 64-bit Windows 8 Pro. People have suggested a fresh install, but it's difficult tobackup everything up and re-installing VPN servers and software through various security measures, so I'd rather not...
I have a Dell Precision 690 with Dual Zenon 3.0 processors running Windows 8.1 Pro X86. CPU on the Performance tab only shows a single processor. I have the identical computer running Windows 7 Pro X64 and it Task Manager/Performance tab show2s two processors.
Basically when I start my laptop everything is good for a while when suddenly the CPU usage goes high because of System Interrupts (~25%) and System (~12%). I have tried using LatencyMon to track down the problem and it used to give me alerting messages but now it gives me messages that are all green and nice ("Your system appears to be handling(...)").
NOTE: My drivers ARE up-to-date, but I am not sure my BIOS is. I don't really know how to update the BIOS though, it's a really weird model I have here, that has become obsolete.
*update1* Upon thinking that it might be the wireless driver or the network driver I disabled both, but it didn't drop the CPU usage
*update2*Now I get disconnected from the internet randomly... it may be the wi-fi driver after all
As soon as I start an application (Cadence Allegro PCB Designer 16.5 but I don't think it's relevant) my CPU usage gets to the roof and stays there long after I killed the application and I believe I every associated process. The CPU usage is so high that the battery will be drained after about 45 minutes (It usually last about 3 hours).
According to my task manager the responsible is "Service Host: Local System (Network Restricted)". As a matter of fact, preventing the executable from accessing the network sort of solves the issue. I don't believe I need that executable to access the network but I'd like to understand what kind of network service can consume that much CPU (was actually affraid of overheating) and to know if there's a more appropriate way to solve this.
I am having problems with my memory it has jumped to 89% and stays there. I tried to restart i looked at the processes it seems that non-paged tools is taking the most. I used RamMAP tool to find this problem.
Over the past couple of weeks I have been getting high disk usage on my computer, causing it to run extremely slowly.
Just after I took the attached screenshot, my System went down to around 6MB/s and the "Service Host: Local System (Network Restricted)" jumped to around 16MB/s Looking in resource monitor the main things causing the high read speed are:
'rundll32.exe' and 'ccsvchst.exe' and one just called 'System'
I recently installed Windows 8.1 on my Inspiron 7520 and I noticed that during the startup the disk usage is around 98/99% of my Samsung SSD 840 Pro 120gb.
I saw a lot of posts where the users complain that, during this high usage of the disk, apps don't open, the system freezes around 5 minutes and after that, there are random high usages, even on idle. But in my case this high usage lasts only few seconds (around 30s), I can open some apps with no problems and never happens again on idle, only if I restart Explorer.exe. If I restart it, it happens all again.
My question is : Is it normal? The high usage only on startup? My only worry is mess up with my SSD due this usage.
On Performance Monitor, the process which writes a lot is System. I disabled every 3rd party app on startup.
I have a new laptop windows 8.1 (64bit) 8gb RAM i7 processor which should be sufficient for the software I use. However on start-up my memory is already at around 80% and stays like that.
The most seems to be caused by servicehost (network restricted) (11) another program is IAStorDataSvc (32bits) even after i updated Intel Rapid Storage it still seems to take some memory. (My system settings are in Dutch but I guess it's pretty much the same as in English).
What could be the cause of the massive memory use?
I'm using the same programs as my old system which also had the same amount of ram (2x4GB 1600MHZ) and the usage was very low.
This PC was only built 4 days ago the current ram is 8GB (2x4GB) Corsair Vengeance Pro, 2133MHz, CAS 11-11-11-30, 1.5V
The first two days that the PC was built I noticed the idle usage at 88% and if i ran a program it would hit 100% and pretty much freeze the PC so it's not an error in the display.
Mobo is MSI Z87-GD65 and I'm running Windows 8.1 with no updates.
Probably not anything to do with it, but i'm running beta amd video drivers and it's showing my card as 5GB, I'm planning to uninstall beta drivers and run updates. Just wanted to know of others opinions.
I bought this Vaio with Core i5-3210M, 4Gb Ram, Windows 8 64 bit. I had really high hopes for it, coming from an i3. For the first few weeks it worked fine, but then it started to freeze while watching movies. Then it started happening all the time, and the cooling fan became consistently noisy for working at full capacity.
I was used to opening task manager on older systems when this happened to see if there was a non-responding program and force it closed, so I noticed Task Manager offers some more features in Win 8. Here, I see that CPU usage is high, staying always around 70% and from time to time reaching 100. At this moment, the process taking the biggest slice is called VCS System Tray with 58%.
What's perhaps more concerning, is that Disk usage is almost constantly on 100%. And by this I mean it reaches 100 and stays there for long periods of time, perhaps up to 20 minutes, then it falls down a few seconds and up again to 100. During this time the computer is excruciatingly painful to use. To even open a program takes forever. When this happens, it seems that Chrome is at the top of the list of processes with most disk usage, with about 1-2Mbps, but this sometimes changes and the list can be led by System, Utorrent, Octoshape, VCS System Tray, Communications Service...I think it's not related to any process by itself, but its nearly ALWAYS at 100%.
Finally, memory usage is also pretty high at 78%, but I guess this may be because 4Gb is not too much for this computer. I'm hoping to upgrade to 8 soon. Out of the 10 processes consuming most memory, 9 is Google Chrome (how's that even possible?).
I have high usage on my laptop lenovo g580 using windows 8. check task manager and I see cpu memory and disk fluctuating up and down to 3% can go up to 100 at times. When I open google chrome. Watch video or play games. I hear my fan turn on and i think my hard drive and i check task manager and i see the problem happening. I did a virus scan and searched everywhere online. I couldn't seem to find a solution. When I am not using the pc its a stable 3 percent but my memory is at 37 which i barely have anything installed but 1 game and a google chrome.
I bought new lenovo ideapad Z400 touch 2 month ago with Windows 8. Last week i upgraded to win 8.1 and recover back to win 8 , since then i have some problems.
When I have the Task Manager open, I notice the disk usage climbing to 50, 75, 100 also the CPU , even though there's scarcely any disk activity going on, the laptop's fan is working harder and very noisy , my processor's speed and heat are jumping high without any programs on.
I tried almost anything, checked for viruses, disabled unnecessary startup programs, clean boot, but it still the same.
Today I upgraded from Windows 7 to Windows 8.1. For some reason, after upgrading, my hard disk usage is always hovering at around 60% usage and my CPU usage is always hovering at around 50%. This is when the PC is idle. When I was using 7, the disk would rarely jump over 30% usage and the CPU would never go above 7% when idle. The sound of the hard disk constantly working away is doing my head in, not to mention it's at around 50 degrees as opposed to 45 degrees previously.
In window 7 it uses maximum 2gb of ram when transfering big file, say an example a movie size of 8gb. now in windows 8 it seems it uses 6-8GB its as if file is transfered into ram first and then slowly copy into targeted disk. just what is going on here and why microsoft decided to do this? if power goes out then all the files is gone and the entire process is actually slower imho.
Is there anyway to disable this? or revert it back to similar what 7 had?
I just got a new laptop with an i7-4700mq in it.. 4th gen Intels.. what does task manager performance tab show? Mine shows the processor at 1% usage, but the speed up at 3.2 GHz which is turbo boost speed I think..
See attached picture for what I mean. I just remember my previous laptop (i7-740qm) would show it throttling right down to less than 1GHz when nothing was happening. I have the latest drivers.
I'm setting up a new laptop running Windows 8.1. I keep finding the Windows Media Network Sharing Service keeps starting up when the PC is otherwise idle and running at 90% + CPU load for long periods. There is no demand for media streaming when the process is running.
What is this process for? Can I disable it or reconfigure it to reduce the CPU load?
I updated to Windows 8.1 last month. It was quite smooth until some issues started 2-4 days ago. I don't remember if I have done something that may cause this, but I'm quite sure that I didn't make any change to the system.
The problem is, even when I am not opening any applications, my fan suddenly blows very strong and makes loud noise. From the CoreTemp utility I notice that CPU usage is 100% and its temperature is much higher than normal. Again, this happens even when I am not opening any applications, and have started the computer hours ago (so it's not starting up).
The most strange thing is that the problem is solved completely when I open task manager. The first thing I see after doing that is task manager itself is taking up ~60-70% CPU, but that number goes down very quickly, and the total CPU usage drops to normal. The temperature shown in CoreTemp drops also and the fan becomes quiet.
Another issue with my current computer is that when I open certain applications (for example, Google Chrome), the process of the application appears in task manager, but in the background. And the application does not show up until 10-20 minutes later.
And when I use Windows Media Player, every song is stucked for ~5 seconds before being played. And there're spikes in the sound.
I've added task manager to my scheduled tasks at logon. Everywhere I google, they say to put the /min or -minimized arguments in it to launch it minimized, except neither option works for me. Task Manager launches, but just sits there on my desktop.
Is there a new argument for minimized in Windows 8?
Considering the issue with Windows 8 restore points getting deleted, I decided to use Task Manager to create a new one weekly. The problem is that if I do not boot into another partition or manually delete the old restore point, they are going to pile up. Is there a way in Task Manager to delete the old restore point before creating a new one?
When CPU usage is just high (50% to 60%) and I open Task Manager, it's usually McAfee on access scanner at work because I've just clicked an emoticon or something like that. Other examples are service host -- some long winded process I can't always find in the TM list to get the name right.
But when it's 100% and this has happened consecutively for over half a dozen attempts to find what spikes this, I'm dead serious: CPU usage has dropped immediately to under 3%. Yesterday and today I've "caught" this thing 2 times. CPU usage drops so fast you can't see what spiked it.
There are 2 Google Ads that pop in right about here but don't show up when I edit the post. These do not work, find hundreds of non-existent "errors" so that you'll buy the program and then when you run it you might get less than half a dozen errors fixed. Don't trust these programs, I don't. I have no control over what Google Ads does but I'd call it anything but "Adsense" to be honest.
I had Norton trial as the default AV when I first fired up and set up the laptop but I'm a McAfee person so set this up and removed Norton during the McAfee setup process. So it's not likely this is an infection. I apply all updates as soon as I see them, if I'm working and can't quit at the time an Update notice comes through then it's no more than overnight that these are applied.
