Performance :: Disk And Memory Usage Spikes
Dec 3, 2015
I've had this problem where my disk usage would spike to 100% before going back down to like 2%. I looked at countless forum posts and different sites and I found something which was a temporary fix, which was turning off tips about windows...
That worked for a while, and it just makes the intervals in-between the spikes longer, and now my memory has started to spike pretty high to about 99%, and wont come back down. When it does this I have to do a hard shut down as my pc just slows to unusable...
I also tried disabling ndu.sys in the registry, which didn't work either.

My computer will spike up to 100% disk usage at random, rare times. It always happens upon startup though and it makes my computer go to a snails pace when I'm getting everything launched up. I used Windows 10, I've disabled Superfetch, Windows Defender etc. but it only seemed to make the spikes slightly less frequent. The spikes sometimes stay for an extended amount of time, even as I'm typing this, my Task Manager says disk usage is on 99% and my computer started up about 10 minutes ago.

I'm running a 64 bit Windows 10 laptop. On idle, the System process is showing a high memory usage of more than 150 MB, usually more than 200 MB. Using poolmon the pooltag SpDN showed up with a memory leak. It leads to the Intel Matrix Storage Manager driver, iaStorV.sys. How should I go about fixing the problem?

I recently bought a new laptop which had Windows 8.1. After a week of having it I noticed my Disk Space near 100%. I heard this was a common problem so installed CCleaner and did disk space cleaner however none of it worked.
I then upgraded to Windows 10 as a friend said this solved the problem for him, however, since doing so either the disk space, Memory or CPU are high either one at a time or all together, regardless of what I am doing on the laptop.
The first week of having the laptop I don't believe this was a problem so I think it's something to do with an update as all games ran smoothly.
When I run a game or bring up firefox near the top is always 'system (ntoskrnl)' or a few 'service host (svchost)'. I dont believe its the games I play or firefox as like I said it was fine for the first week. It seems windows are running stuff behind the scenes.
I have done a few things that I have found on the internet but none have worked like; disable prefact and superfetch or whatever they are called. Still seeing increase in memory or disk usage whenever i load something and system or serice host are there at the top of performance or the game seems to use alot - however again the game never did this in the first week.

After installing Windows 10, I have consistently been getting high memory and cpu usage by both the System and Service Host: Local System processes. Usually the usage keeps rising from 1GB to sometimes 8GB. I left my comp on while I was at the gym today and came home to it prompting me with a low memory available message. This must have shut down some processes because now my pc is running at 13% memory and 2% cpu. I have searched for this issue and found similar threads, but none of the solution work for me.

A while ago, after upgrading to Win10, my memory usage jumped to 99% percent while watching a movie via VLC player. I couldn't find anything in the task manager that seemed to use up all 16 gb of my memory, the new layout of task manager confused me a bit, so I simply rebooted. Fixed the problem.
Today The same thing happened to me again, except this time the memory usage continues AFTER a reboot, and then another reboot. My desktop computer seems completely possessed by whatever is using up my memory. I consider myself to be a very advanced user, although not a professional, but I can't figure out how to nail down this culprit via the task manager. Nothing seems to be using up a lot of memory, the total of all the apps isn't close enough, yet it does identify my memory usage at 99%. There were no unusual apps running in the background, just VLC running an HD 1080p movie, which I have done many times on that computer.
I can imagine this will happen again if I don't find the issue. Where to start troubleshooting to find a memory hog that only happens once in a great while? Does it have anything to do with windows updating itself secretly and automatically now?

When I am downloading something with utorrent the memory usage in task manager slowly creeps to 100% and makes my computer unusable and even if I shut down utorrent the memory usage does not change and I have to restart my PC. Same goes for browsing facebook or any other sites. Is there a solution to this? I really don't want to reinstall my system.

I have 4GB of DDR3 ram on my laptop. When I go into the task manager to check how much ram is being used, it says only 795MB and yet it also says that 94% is being used.
This is always the case, of course with varying numbers. The memory usage shown does not coordinate with the percentage, but the computer performance certainly correlates with the percentage.
When I check in cpu-z, it does confirm that the 4GB are all installed. What is going on here?
Updated with pics:
I missed the performance tab which does indeed show all of the correct total amount of ram being used. Now how do I find all of the individual processes and services using those resources?

since not too long, it takes 5 minutes to my pc's disk to go back to low percents. It takes around 5 minutes when I start the PC to go back low and sometimes it spikes back up to 100%.
The program i see the most going up is System and Compressed memory. I disable supertech and ''windows search'' each time I start my pc, I turned of all the notifications options except for app notification and I turned off the cloud-based protection but it still happens.

I am running Windows 10 Pro. Over the last couple of days, for some reason, the OS reports 100% disk usage, even when no application is apparently running. It was quite alright a few days ago, but troublesome over the past 2 days. I had assumed it was running some background task, and would become normal, but the abnormally high disk usage persists even after the machine has been running for half an hour.
In this period, no Windows updates were installed, and only a scheduled checkpoint was created 4 days ago. If I try and restore to the checkpoint during boot, I get an error, saying the PC needs to be repaired. If I try it from the recovery option in Windows 10, it does not shut down for a restart, just keeps on the blank screen saying "Initializing restore". The entire time, according to the indication light, the disk seems busy.
I tried disabling superfetch and background intelligent transfer service, but did not work. The spike in disk usage is not specific to anything, sometimes it is the system, other times the malware service...
I do not wish to reset the laptop, as I had quite a few things installed, but I do not have the installation media for those anymore, and so would not be able to install them again after the reset.I have the installation iso for Windows 10. The laptop is Dell 17R SE 7720. I had upgraded to Windows 10 Pro almost 2 months ago, and it had been running fine.

I'm getting a constant high disk usage without even having anything running. Here's a screenshot of my problem
And well, so far I've tried the ''deactivate 'windows search' and 'superfetch''' and it hasn't really done the trick.
Also I resetted my pc yesterday, as of now I'm running a clean install of Windows 10.
Did the ''turn off notifications from Windows'' and really nothing, I've also defrag quite some times with Defraggler and DiskDefrag and nothing.

I need diagnosing why my system disk is running at 100% without anything actually running.
My Anti Virus is not doing anything, windows update is not doing anything, and my disk is not defraging.
I would have never noticed this happening if it wasn't for long load times and reduced FPS in anything 3D. My mouse and keyboard even are lagging and hanging.
My system disk is at 100% and a constant write speed of 1-2 MB/s and a constant read speed of about 200KB/s.
How to diagnose what is using my disk 100% of the time?

Since I upgraded to Windows 10 from Windows 8.1 (who knows when, within the week of first release) I've had a plethora of issues, and recently I found the source of the problem. My computer spikes to 100% disk usage randomly, even with nothing open and will suspend all applications on the computer. A couple of random things can set it off (sometimes when I open the "Search the web and Windows", open an application, Ctrl+Alt+Del, and ALWAYS when I boot my computer)
I've tried every. single. thing. that I have seen on the internet including but not limited to: superfetch, registry stuff, Unistack thing in task manager, Windows defender, uninstalling programs, defragmenting my 1TB Western Digital HDD even though it says 0% fragmented, cleaning up my HDD, checking if my HDD died which it hasn't, and updating my drivers, stopping all startup programs, disabling unused Windows apps, though nothing has seemed to fix the problem permanently. I also used to get this "Display driver AMD has stopped responding but has recovered" though I edited something in the registry and it doesn't show this anymore but I still experience the same problem. I'm quite fed up with this, and I'm thinking about buying Windows 7 in an attempt to downgrade.

I'm not sure what type of issue this is so I've posted this in the Performance & Maintenance, Gaming and Hardware categories.
Anyway here's the thread: 100% Disk Usage when running GW2 - Windows 10 Forums

For some reason, my disk, when i open my computer and at some other point, always spikes up to 100% for a few minutes.
This happens when :
at the start, Something called System and compressed memory always make my pc go to 100% disk usage. Later on, there are all those Service Host going up to 100% and something called RzStatsManager
When i open norton or when i download something new it also goes to 100%, each time I open google chrome too and Steam make the disk go to 100% at the start and every time i open it it goes to 20% and the system memory goes to 80%...
All these times, the disk spiked at 100% for a few minutes.
I disabled all my notification, each time i open my PC i disable Windows search and superfetch but it spikes up every time. What can I do?

I have this issue where windows seems to hang/get stuck every 5 to 10 seconds for about 2 seconds, like right now while I am typing. I type the words and about three words types out and then hangs for 2 seconds and the rest I typed while stuck gets lost and I have to backspace and restart again.... Same happens with mouse clicks, sometimes when I click it does not register (I presume it is right in that 2 sec delay sweet spot) but the mouse cursor movement is smooth and does not get stuck.
SO I checked my Task Manager and found that RAM,CPU and Network are all low in the 10% - 20%, but my HDD Runs at like 80% -100% all the time. See Screenshots of Task Manager and Resource monitor. The disk keeps getting used full load every 5 to 10 sec.
I have tried disabling Disk Defragment service in the Task Scheduler and several other tips I found on the net but no luck.

I started experiencing this after my brother installed some malware on my pc while playing CS GO. I have removed all the malware i could find and have ran memory and disk tests which have shown me nothing but positive results, but when i run furmark the disk usage climbs to 100%. I also have noticed my nothbridge overheating which might be the issue. I also have a shady 600W psu that needs changing because it is old and I don't trust it.
I have
CPU: intel i5 3330
GPU: Nvidia gforce gtx680 refrence
RAM: 8GB kingston value ram
PSU: 600W super cheap generic psu that came with the case
HDD: wdc wd5000aakx-001ca0 500GB that needs changing
MOBO: msi MSI H61MA-E35 (B3)
[code]...
Edit:I found out the reason for my hdd stopping while under load was that one of my 6 pins was a 2molex to 6pin adapter and one of the molex cables was also the one powering my hdd through a sata power cable.So i plugged in a different one and now it's fine.

I just upgraded to TH2 from Win 10 Pro. I noticed that my disk usage is near 99% for the past 20 mins. It keeps fluctuatiing between 10 to 99. Normally my disk usage stays at 0. May be this might be Windows settling in after the upgrade? There was high disk usage the first time around when i upgraded from Win7.

I have win 10 64-bit home on a 4th gen core -i5 laptop. I have a WDC 1T 2.5" USB3 drive. It is about half full. It used to do 60-70MB/s write speed. Since a few days ago, I noticed it has slowed down by a factor of 5-6 to 10-20MB/s. While copying large files, I watched what's going go. The System and compressed memory process was doing a lot of read and write on the disk. If the copy speed reported by the dialog is say 15MB/s, then system compressed memory process is reading 15MB/s and writing 30MB/s. It looks like this process is reading back the content written and writes back. It is consistent over reboot with several large files from 200MB to 7GB in size.
A couple of weeks ago I did a file backup. I created a 5GB virtual drive on my SSD and dumped all files to be backed up. Took only 5 minutes to copy the 5GB files to the virtual drive and copy the file to the WDC disk, at around 67MB/s, typical of this type of portable drives. While I was wondering what was going on, I tested the same files with a USB3 dock and a 2TB Seagate drive. Write speed is about 150MB/s. So I thought it was not a problem with all disks. The WDC drive has no compress to save space option, BTW. I wonder what's going on. I have AVG antivirus and I turned it off while copying and same slow 15MB/s speed.

I just installed win 10 last day, and it was going fine, no conflicts on the drivers whatsoever. But after a day, when I booted up, it seems to have slowed down to a point that everything does not respond to my inputs, though it does after a couple of minutes, i check the task manager and it shows that the disk usage is high, the r/w speed show high utilization about 10-40mbps and the active time is 100%? I have read some thread and suggested to turn off superfetch and prefetch but that didn't do a thing to me. Btw, I installed it over win 8.1 using a bootable usb.

I've been having this problem for a long time, I've tried resetting my pc to factory settings, didn't work. I tried windows trouble-shooter, didn't work. When I boot I am greeted with a zoostorm logo for about 50 seconds followed by a black screen for 1 minute, and then a windows screen for about 30 seconds. Booting takes about 2-3 mins and even when I'm finally in, my programs load extremely slow and I can only open chrome after a minute otherwise it lags. Remember I have reset my pc so nothing runs on startup apart from steam.
I have a gtx 970 and the latest drivers for it. Also I get 100% disk usage when performing certain tasks. my cpu,gpu and memory never go to such percentage and if they do its because I'm running a very cpu,gpu or ram intensive game. I have not changed anything in my bios since I got my pc and have never done anything to the disk drive (all I know is my HDD is 3tb and has a speed of around 120mb/s) The only thing I have changed on my pc since I got it was an upgrade to windows 10 from 8.1, gtx 970 from a 750ti and a 750w power supply by corsair.
I do not know if this problem happened when I had windows 8.1 but even if windows 10 is the problem there must be a way to fix it as I despise using windows 8.1 anymore. Another thing to note is that loading times for games take a little longer than my friends and my pc is slow at downloading games, my disk usage when installing games is usually 13mb/s and I get 100% disk usage from using 13mb/s. As you can see by this screen shot steam is downloading fallout 4 and 14mb/s of my disk are being used and everything else barely reaches 1mb/s

I dunno whats happened all of a sudden. but after doing the recent windows 10 update (Major update) most of the games i play and applications i use are now becoming unusable!
Certain games and or applications are going to 100% disk usage which cripples performance until i close the game or application down. then everything returns to normal...
After doing a bit of digging ive came to see that its always the same issue
Image > File Name
Archeage.exe > Pagefile.sys
Photoshop.exe > Pagefile.sys
etc etc..

From sometime in October, after an update, there have been periods, sometimes intermittent, sometime persisting for a long time, when Disk usage spikes up to 100%, and makes a lot of things unusable.
I did some researching, and disabled a bunch of stuff, like Windows notifications, Windows search, background intelligent transfer and superfetch, even OneDrive, but even on Windows 10 version 1511, Disk usage spikes to 100%, the offending application / service being anything from System to memory compression to 3rd party applications...
This is becoming extremely irritating, and my video playback or something else stutters a lot when disk usage jumps up, often at chronic levels, then backs down, or stays at that usage for some time.

My laptop suddenly started lagging a lot. I opened Task Manager and saw that the Disk Usage was at 100%! The only things causing it to rise are the essential Windows Programs. This causes so much lag though, that if I try to run more than 1 application at a time, nothing starts responding and it forces Me to Force Shutdown manually by holding the power button. I tried a new Browser (went from Firefox to Chrome) and still the same problem. I decided I want to upgrade to Windows 10, since I'm qualified to have it free, but whenever I try to install it, the "Checking for Updates" loading bar never finishes and if I try to close it or anything else, it'll freeze up all over again.
What should I do? I had to go into Safe Mode to be able to make an account here and type this up. I've already uninstalled some stuff, even though I barely have anything occupying a lot of space to begin with. I certainly didn't download anything malicious, as the day before it started lagging, it worked absolutely fine and haven't downloaded anything from then on.
