Ntoskrnl.exe And USBPORT.SYS Causing High CPU Usage
Nov 7, 2011
I just upgraded from Windows XP Pro to Windows 7 Pro x64 last week and I am already experiencing some issues. The most pressing is that I am experiencing stuttering after I have been using the computer for varying lengths of time. It can occur within a few minutes of first booting the computer or it can happen within hours. The time also varies depending on what I am doing, either normal internet use or gaming. I have updated all my chipset and hardware drivers and it was still occuring. So, I looked into it a bit more and found suggestions to run the xperf program to find my high CPU usage. It comes up with ntoskrnl.exe and USBPORT.SYS as causing the highest amount of usage. I also ran LatencyMon after seeing several suggestions for that program as well. It also comes up with ntoskrnl.exe as causing the highest amount of CPU usage. Aside from updating drivers, I have also tried reinstalling Windows a second time with no luck.

For the last week or so, my network traffic has seemed to be related to some pretty sever spikes in my CPU usage. These spikes are causing extreme stuttering in my music playback, freezing of my cursor, and other symptoms of a really laggy computer. This pretty much occurs whenever I use the internet in any way. The worst spikes are when I'm loading webpages in Google Chrome and seeding on uTorrent, often freezing my cursor and music for several seconds at a time, though they're not limited to those two softwares. More recently, it seems that when I am loading pages in a browser, it's spiking CPU usage in bother the browser and even more so in the System process. It's becoming a real issue to use my computer.
On a side note, I've noticed that the displayed memory usage in the task manager (2.74 GB) is way more than what all the processes appear to add up to, usually by more than 1 GB.

I just upgraded to Windows 7 (64 bit) last weekend by doing a clean install from a win741.com purchase. I am currently using a HP Pavilion a6500f computer with a 500GB hard drive. I have been getting BSOD errors over the last several days and it is driving me crazy. I am considering going back to XP or Vista if I can't get this fixed soon.
All of the mindump files mention USBPORT.SYS. I'm assuming that has something to do with my usb ports which only have the following items attached:
HP Deskjet F4280 Printer Linksys USB Network Adapter WD 500GB My Passport (plugged in some of the time) I ran Driver Detective to see if there was an out of date USB driver, but nothing showed. I've included some screenshots of the scan.

I've got this new laptop last month and after two weeks got my first BSOD. I've done chkdsk, sfc, and last know good config only to have it back again every 3 days or so. I don't have restore point far back enough and don't think I've installed anything that could cause this. The driv'ers are up-to-date, and I don't have Norton or AVG just Kaspersky Internet Security as my antivirus. But I do play LOTRO but at the lowest graphics quality. I don't have any CDs and the laptop didn't come with a Windows disk so I can't repair or reinstall it to its factory settings. Sometimes the BSOD appears when I starting shutting down, otherwise its random.

I just installed windows 7 ultimate sp1 - Like the title says I'm seeing 35% cpu usage with nothing going on. I googled around and ran traces to see which driver it was, turned out the ahci driver was doing it. The USB driver showed similarly high latency but that can be delt with later. Most forums recommend upgrading your drivers but this problem has stayed constant both with microsoft's stock drivers for everything and after running windows built in search for drivers even after I manually grabbed the latest drivers for everything. url...BIOS is up to date4 GB RAM - Corsair something or otherEVGA Geforce 8800 GT450W psu1 DVD burner (sata)5 hard drives (sata) plugged into all but the first sata port because that caused nothing but headaches for me. Update - switching from AHCI to IDE in BIOS fixed the problem.

for about 2 months now, every time my laptop does something involving graphics (usually playing games or watching a video on Internet, or anything involving flash), i'll notice that my cpu usage spikes to 100%, which causes slowdown, i.e.: gameplay/videos will be slow and choppy, sometimes freezing for a few seconds to a few minutes before resuming. it usually does this in intervals, i'll have a few seconds of normal gameplay/video and then the freezing. considering that this also happens when i play offline games, i'm suspected that it's my graphics card that is the culprit.for reference, i'm using an ati radeon hd 3200 graphics display adapter on my laptop. i've tried updating the driver not too long ago, which ended up installing the ati ccc, but the problem still persists. i haven't had this before and the games/videos used to work fine.looking in the task manager, i see that its the application that i'm running that's hogging the cpu (either firefox for Internet/flash or even stuff like tf2 and maplestory).

I've been having this problem where my CPU is constantly hovering at around 30% usage, and after investigating with ProcessExplorer and Task Manager, I've found that the process responsible for most of it is the "System" process in system32 (the description says "NT Kernel & System"). Unfortunately, nothing seems to be able to pinpoint what exactly is causing this process to be using so much of my CPU. The reason this is so annoying though is that when the System process reaches 15% or higher CPU usage (which is does pretty frequently), any sounds my computer is playing stutter very obnoxiously. This makes it really unpleasant to listen to music or try to steam videos with sound while my CPU is constantly spiking. how to troubleshoot this or some common causes of these symptoms?

My CPU usage (Intel i5) meter always reads just fine, usually around 5-10% during normal tasks. Well, after my computers been in sleep mode, and wakes up, it always shows that Core 3 is usually up around 50-60% and Core 1 around 20-30% or so... It never goes back down until a restart/shut down.Also, I own Driver Reviver, which suggested like 9 new driver updates for me, and I still have the problem.

(Sony Vaio) has been extremely slow lately, which I am assuming because the physical memory is constantly high (up to 95% at times) even when I am not doing anything. Below are some screenshots for information. I have tried killing some processes but cannot find one process that is a major problem. 52 Processes are currently running which doesnt seem so excessive. Is it normal to have so much memory reserved for hardware?

Whenever I am on my computer My RAM usage is really high. More than I think I could ever use up! When I am not on an App/ Browser my RAM Usage is still above 50-60%. I also think my internet connection has something to do with it because when ever I try to load a video/website it takes more than 10minutes to load a 30 second video!

I have a very high cpu usage for some reason. I wont even be at my computer and I can hear it working away.Take a look at the picture. I wasn't really even doing anything. I have itunes open, mozilla, skype but not doing anything.I've looked at the processes and it seems normal. Firefox is always top.

I don't know if I'm just overthinking/worrying too much about my laptop, but my CPU usage lately seems to idle between 10 and 30% even when I'm not doing much. I've noticed that TeaTimer.exe (Spybots real time protection) seems to hog some of this, and I'm not sure if I need it since I have Malwarebytes and SuperAntiSpyware installed. I've also noticed Firefox to be very laggy but this could well be a seperate issue. Also on startup my computer does seem to take up to five minutes to settle down after logging in.What can I do or what should I be checking?

I just reformatted my computer to windows 7.
And i'm kinda disappointed on its performance compared to some reviews i've seen in the web.
It seems that my computer consumes alot of RAM if i'm not mistaken.
Here are my processes and memory usage:
i have 4gb ram installed, but i installed win7 x32bit.
So when i on photoshop or other program that uses alot memory, the ram usage goes to 1.6-1.8 GB.
And during that time i felt some lag.

Lately, the cpu usage on my laptop goes very high without no reason. It sometimes bursts from 10 to 100 percent without any apparent reason. Looking into the task manager and sorting the procceses by cpu usage reveals that no single process uses very much cpu,instead about 10-15 percent is used by multiple services each.I run an Asus laptop k73s with an i5 2430m proccesor, an nvidia gt540m, 4 gigabytes of ram and windows 7 ultimate 64 bit. I tried everything from doing registry cleaning and repairing to disk formatting and virus and malware scans. Each attempt to no avail.

I have noticed when Iam downloading at full speed of 1.8MB/s on Wifi or LAN there is high DPC/IR (Deferred Procedure Calls and Interrupt Requests) CPU usage - and when transferring files in or out to USB hdd.. i sometimes get pops & clicks in audio too - the CPU is a Turion 1.8Ghz x2 with 1Mb L2 cache and 2Gb of ram, DPC/IR can only be seen using Resource Monitor in windows 7 (type 'resource monitor' into startsearch) or using Process Explorer software, I dont know much about DPC/IR but as far as Im aware it handles errors or something like that and I was told it should never even go beyond 1% cpu usage - its more noticeable on laptops as these have CPUs that arent as powerfull as desktops and have wifi, it seems to be worse with wifi. it causes latency problems in windows too and things like audio playback get pops & clicks and windows & apps become sluggish.
What brought it too my attention was the CPU fan on my laptop was on all the time and windows seemed to be sluggish when I was downloading even though uTorrent was just using 3-5% CPU, I noticed the total at bottom of Task Manager seemed to be more than what would tally up in the window, it was when i used resource monitor that I seen it.
WiFi @ 1.8MB/s = 10-15% DPC/IR cpu usage
LAN @ 1.8MB/s = 5% DPC/IR cpu usage
Copying Files to USB HDD = 15% DPC/IR cpu usage (this test was odd as it was some time ago i done this one, but I remember it was either IN or OUT that had the increase, probably IN (and OUT was <1%) , I tried SDcard too and got varying results)ive even seen it max at 40% when downloading on wifi and copying a file in/out too usb hard-drive at the same time...

I was using vista x86 up untill windows 7 came out, it was the I decided to go for my first x64 operating system. I have an i7 and 3gb ram.
Ever since I've moved over, games take up a stupid amount of memory, they'll go to 80 - 90%. I recently decided to install Crysis Warhead as I never got round to completing it, last time I played it I was on vista x86 and it ran fine. However now, it takes forever to load and/or freezes because there's no memory left.
I've tried setting the page file at 200 - 1024, 1024 - 1024 and turning it off, none of that makes a difference. I tried increasing it to 4096-4096 just out of curiosity, that managed to load the game, however, while I did have a constant 50-60fps I was lagging really badly and had 91% ram usage.
Am I missing something here, does anyone else have this issue?

I have a Lenovo laptop with Win 7 Pro.
When I leave the laptop on standby, and come back to it after 10 minutes, the fans are blowing loudly. I have a CPU gadget which monitors CPU usage, and I see that right when I resume from standby (move the mouse), CPU usage drops to normal.
At first I thought Security Essentials is doing some scanning or windows is indexing some files, but this happens every time the computer is idle for longer than 10 minutes. I have a suspicion that my laptop could be part of a bot network.
