Maintenance :: CPU Usage Won't Go Over 50%?
Sep 15, 2014
I have Intel I7-3930K running at 3.9GHz and I've noticed that my CPU utilization never goes over 50%, even when rendering, or playing cpu demanding games like BF4. It's also causing huge hiccups(CPU spikes) every 2 minutes or so, while playing games. I've installed all windows updates and latest drivers, disabled all unnecessary programs and tasks.

I'm playing watch dogs which needs 6GB ram on a 4GB ram PC.
I run compact tray meter and one thing I notice is that the ram usage never goes more than 80%. In fact, whenever it loads stuff from the HDD ( I could see HDD usage 100% and stuttering in my game), RAM usage decrease to 77-78%. VRAM is kind of healthy at only 52% of 2GB used.
I want to know why not all 100% of my RAM is used? Hardware reserve is only 145MB.
And why is the minimum system requirements for watch dogs a GTX460? I mean, I got a 645M, I can play it, my friends with a 640 and 630m can play it fine, our GPU temperature is just 80"C even after hours of playing.

Randomly my disk usage will rocket up to 100% and sit there locking up my computer and freezing things that i am doing. problems started right out of the box when i got my laptop. CCleaner seemed to lower the amount of times it happens, but it still occurs. I've ran virus/malware scans there is nothing. so its ether windows doing stuff on its own randomly then consuming my whole disk or its having compatibility issues with some program that i have running. this is interfering with gaming and school work. I will include pics of multiple instances of it locking up. I can also include a list of the programs I have on here.
i have an
Acer Aspire V3 772G 9653
intel core i7 - 4702MQ
Nvidia Geforce GTX 760M
8 GB DDR3 memory
1 TB hard drive

For some reason my disk usage is always at 100%, it never spikes its just a constant 100% and i think its hurting my performance, is there any way to lower this?

After putting my computer to hibernate and powering it back on, my disk usage would stay at 100%. All the transfer speeds are around 0.1 mb/s and I'm not sure what could be causing the 100% disk usage.
Another thing is that it windows notifies me to scan my hard drive for errors, which I have done, but this keeps repeatedly happening.

I've been on 8.1 for some time now and just noticed that my CPU usage is always showing up in Task Manager as 100%, no matter what combination of programs are using it. No single program seems to be the culprit for hogging it. The usage values bounce around like crazy, but the column total is stuck at 100%.
I don't notice any lag or slowness as a result like I should if the CPU WERE at 100% load. It's an older Core i7 Quad in a Dell Precision M6500 laptop.
I am quite OCD about things running in the background unnecessarily and have disabled a lot of startup items.
I put a screen cap here, but it isn't perhaps a great example since SnagIt APPEARS to be hogging the CPU to do the capture, but I can assure you, it is not this intensive. If I quit that, some other random process just takes 30%+ and others keep filling in the gaps so that the total is always 99-100%. Very strange. If NOTHING else is going on, Task Manager will shoot up to near 100%.
Is Windows 8 supposed to have a System Idle Process?
The other thing is that this machine's fans are NOT running full blast to keep heat down like they would if it were under full load. Is something just not reporting right?

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 encountered a problem a few weeks ago after I refreshed my laptop when it started refreshing the desktop constantly to the point where I couldn't do anything. After the refresh, the desktop was back to normal, though I noticed my disk usage in the task manager was constantly at 100%. I've been troubleshooting this problem by upgrading from Windows 8 to 8.1, I've run chkdsk.exe /f /r, I defragged the disk, ran a virus scan, etc. The only thing that is disabling the service 'superfetch' and/or 'Windows search', though the problem can still arise after doing so. Every now and then the disk usage goes back to it's regular 2-8% but then randomly shoots back up to 70-85-99-100%. It's causing some occasional slowdown.
Here's a screen cap of my resource monitor when it's at 100%:
And here are the specs of my laptop:
-Model: Acer Aspire V5-552
-CPU: AMD Quad-Core A10-5757M @2.5GHz
-RAM: 6GB DDR3 Memory
-HDD: 1000GB
-OS: Windows 8.1

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 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.

I did a fresh install of windows 8 twice and the problem still persists. I think I have tried every solution offered by google so far and I am at my wits end. It causes freezing in video games and I just want to play all these cool games I bought on steam, not to mention browse the internet without freezing.

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.

I have an issue that has been happening since last week i think. The problem is that even with the computer in idle the disk usage has these spikes. When i want to play a simple .mp4 file it freezes several times and the all computer freezes when the spikes reach 100 %. I don't know what is causing this issue.

No matter what I try to do normally my physical memory usage never seems to exceed 31% even if I'm doing something that means the processor is flat-out. However, I gave the system stressing tool 'HeavyLoad' a whirl and it did deplete all the memory (eventually), but in terms of whether I'm watching 5 HD videos or working on Photoshop it just will not budge.
To find attached resource monitor screenshot and task manager screenshot taken after the PassMark benchmark software memory test has been run.

I found a lot of 100% disk usage problems and their solutions, but none of them could fix mine.
So here is my issue : every time I copy files from one disk to another or even within the same disk among partitions and install a program/game, my computer becomes extremely slow. A single click is responded after 3-4 seconds. When I open control panel, it shows 100% disk usage. As soon as the file transfer gets over, everything becomes normal.
My problem is not my transfer speed. It is that while a transfer is happening, nothing else works. Even though the transfer rate is 6 -7 mbps

Windows 8 Genuine 64 bit
2GB DDR 3
Dell Optiplex 3010
Now the problem is there is one service Service Host: Local Network Restricted it consumes 100% disk usage and computer starts acting. I have to manually kill this process from task manager around 4-5 times to end it.

Edit: laptop might also chrash while in airplane mode, however making an internet connection is still a surefire way to make it crash.
Seemingly out of nowhere my laptop has been freezing usually minutes after I started it up. I can then restart my laptop and it works for another few minutes and freezes again. While looking at task manager I noticed the disk going up to 100%, however the individual processes did not account for this 100% use.
I tried to increase/decrease my virtual memory but this did not seem to have any effect.
When My computer makes an internet connection for something, a browser or a game, it will skyrocket the disk usage to 100% and freeze. I can start my laptop with all processes and services enabled and when I put it on airport mode nothing will be wrong. however once I enable internet and surf around for about 1 minute my computer will freeze. this happened for multiple browsers and also for multiple games. Also I am currently typing this from my brothers laptop with the same internet connection.

I don't know if this an 8.1 or an Office problem, as my previous version of Outlook ran under 7. However, that version didn't need to hog 12-13% CPU all the time, whereas this one does.

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?

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

I'm not sure if I'm using File History properly, even though it seems to be a plug-and-play type of feature. The situation is: when I leave my USB Flash Memory device plugged into the laptop, and the frequency of backup is set to every 10 minutes, it seems that some of the memory is being nibbled away at, even though I haven't created or changed any files.

The new Windows 8 touch laptop I just got is running ridiculously slow. Apps take minutes to open sometimes because the disk is constantly being used by several processes, even when idle.
The main culprits showing in Task Manager are "Service host: Local system", "Windows Modules Installer Worker", and "Antimalware Service Executable". Between them they are using 97+% of the disk and about 50% CPU constantly. It's gotten a bit better since I uninstalled all the trialware garbage that came on it, including McAfee, which was a massive slowdown. I plan on just using Windows Defender for security but it still says it's turned off, could that be the problem?
But for real, I'm pretty sure McAfee slows down the system more than the viruses.

I've been having some major problems with Windows 8.1 (and 8.1 Update) which never occurred to me in Windows 8.
What essentially happens is that the computer completely freezes up and I know that the disk usage goes to 100% as does the active time but the read speed/write speed and average response time are all 0. During this period, i cannot do anything with the machine, not even take a screenshot (And hence to poor quality of the attached picture which shows the scenario).
I've encountered this problem in all of the situations: Upgrade from Windows 8 to 8.1 via StoreUpgrade from Windows 8 to 8.1 via flash driveClean install of Windows 8.1 on to a formatted partition
I've never had this problem with Windows 7 nor with Windows 8 and I've gone through the process of trying to upgrade to Windows 8.1 more than 8 times (literally) on my laptop. I've updated the drivers from the vendor site.
I also encountered this same problem on my desktop once when I performed a clean install on it but I need a stable configuration on my desktop for now for work.
The following are the steps that I've seen online as solutions to this problem and have tried all of them to no avail:
Disable superfetch and windows search servicesDisable Link State Power Management for PCI expressDisable live tilesDisable page files
The configurations for the laptop are as follows:
HP Pavilion dv6-7040tx
3rd generation Intel Core i7 3610QM8 GB of RAM750 GB SATA harddisk (Currently has three partitions plus the small partition created by windows. This problem existed even when I had a single partition. The reason I re-partitioned was ease of formatting and re-installing the OS alone without clearing my data)NVIDIA GEFORCE GT 630M 2GB graphics card.
I do have all the latest drivers from the HP website and the latest updates from windows update. Also, if I check the resource monitor, at these times, the actual disk usage is indeed at very low rates for the different processes. I've attached a snapshot of that as well (had to use a camera then too). Notice the long gap during with the disk active (blue line) is 100% but the speeds (green area) are 0.

I have a laptop running Windows 8 Pro x64, and lately I'm facing an issue where the System process (PID = 4) has spikes of 100% of disk usage according to task manager. I can't watch a video or play a song on a media player properly, for example (there's a crackling noise and the playback is slow), because this process (System) keeps using 99-100% of my hard drive.
Even if I have just booted up and running only the essential OS process and services and completely idle, task manager keeps reporting several spikes of 100% of disk usage. Tried uninstalling antivirus (avast free), but that didn't work. I really have no clue what do to prevent this process from writing/reading so much into HD and reaching 100% of disk usage.
Specs:
OS: Windows 8 Pro x64
CPU: core i3-2350M @ 2.3 GHz
RAM: 4 GB DDR3 @ 1333 MHz
HD: Samsung Spinpoint ST500LM012 HN-M500MBB 5400 RPM
