CPU Usage Spikes, Jumps From Perhaps 10% To 70-80 %
Apr 10, 2008
I have a Toshiba notebook with Vista Business installed. Recently I installed the sidebar and added the "CPU performance meter" and noticed that it was constantly in motion. Looking at the Performance tab in task manager, I see that the CPU(s) (dual core) are very priodically show spikes. Every 4 to 5 seconds, the usage jumps from perhaps 10% to 70-80 %, and then goes back to 10%.
The laptop shows this bahavior over long periods of time, even if no application is running. Looking at the processe that are running, it appears that one of the "svchost.exe" (of which there are quite a few) seems to be the culprit, but I have no idea what is behind it. How do I find out what this process is actually doing? Can I simply end it to see what happens, or will that harm my laptop?

When using any icons view in explorer.exe with a folder containing MPEG-2 video clips, and/or having the details pane switched on for such folder, explorer.exe eventually uses up all available memory until windows fail to redraw. Restarting explorer.exe or the computer temporarily fixes this problem until all memory is used up again. The problem can be reproduced with folders containing MPEG-2 clips. Other file types do not seem to trigger this behaviour. The process running on explorer.exe while memory usage jumps up is the following: RunDLL32.exe "C:Program FilesMovie, Makerwmm2clip.dll",VMGShellThumbnailGenerator "{FileName}.mpg" 256 256 0,Is there a known fix or workaround?

since a few days my cpu has always cpu load of about 90 % at core 2. Vista is very slow. Taskmanager shows no applications with cpu usage. Now i installed process explorer and i can see that 45% cpu usage (this is 90% of core 2) is for "System / hardware interrupts". Which interrupts are the problem, what can i do to fix this?

Basically im quite upset and angry at the fact i just bought a beautiful new machine, thinking ill be able to finally game propelly, to only find that.. I get these 2-5seconds where my gaming ( World of Warcraft ) freezes completely. Basically from what i've read its something to do with Vistas wireless that searches for a new and better connection every 60seconds. My computer is NOT connected to the router, it has a 3/5 signal strength and my ping is OK. Its just these lag spikes that are killing me. I've tried VISTA Anti-LAg and the WLAN optimizer. Nothing works at all. Anyone have ANY other suggestions as to what i can do to get rid of these 2-5second lag spike/freezes with my gaming? Im running VISTA Premium x64bit...

my problem is that every few seconds my PC suffers from a quick CPU spike that lags the PC's frame rate, but not sound. I've tried running safe mode and this problem does not happen, which says to me that it's a driver problem. i've checked through Windows and my drivers are all up to date and i have problems updating my graphics drivers manually from the website. the spikes arn't a major problem for generally use but it makes reaction based gaming (FPS for example) incredibly hard.
i've also tried:
• checkdisk
• sfc /scannow
• defragmantation
•virus scans
and some other possible "solutions" i've found across the web.

I have narrowed down my serious start up degradation on a Gateway ML3109 to spiking CPU and Disk activity as I start up and do almost anything on the notebook. Something is making various services, apps and drivers throw up errors about taking too long to start-up and shutdown. I thought I had narrowed it further to Sound drivers but updating and repeated reinstalls only reduced the sound-related errors. I'm almost sure this is hardware because I have done two clean reinstalls of just the Vista Basic system and it doesn't change. I thought it could be the generic drivers Vista's install disk uses, so I replaced every driver I could find on gateway's website for my model (only chipset wouldn't download, saying my system didn't "meet minimum requirements" even though it was downloaded from Gateway for my serial number) but the result is just fewer errors at each startup, or shutdown, in the Performance-Diagnostics>Operational log accessed on the Advanced Tools panel.........

Topic pretty much says it all. It happens when I play numerous games - Counter-Strike, Warcraft III, etc. This has never happened when I had Windows XP. I've searched the forums for a solution but have yet to find one. I'm using 'Win Optimizer' right now and I still get spikes (more frequent as of lately). Anyone know a "fix" or solution for this problem?

I'm sure this has been reported by several individuals before me, but ever since I have been playing World of Warcraft wirelessly on my new notebook with Vista I have been hiting these lag spikes every couple minutes, that can range anywhere from a second to 15. During this time cpu and disk spike to 100% usuage. I have tried updating my drivers for my NIC and my graphic card, as well as disabling a roam feature on the vista wireless network, but these have not halted the dreaded spikes. Also, I have tried playing while directly connected to the internet but even then the spikes occur. Does anyone know what is causing these spikes and what can be done to solve them?

This does not necessarily always happen but some times the mouse pointer jumps away to the top left corner area from where I click. Is there a remedy to stop this from happening?

This has been going on for quite a while but its getting to severe points. What's happening is basically explorer.exe jumps straight to 95-99% when vista boots and remains like that without budging, resulting in extreme slow computer performance. Attempting to close the explorer then restarting will temporary bring it back to aroung 50% but it will soon jump up again, restarting doesnt work.
Here's the stuff Ive tried to do:
1- Got rid of the index.dat files in the TIF, apparently they slow performance.
2- Turned off search indexing
3- Tried to defragment the memory, but it doesnt do anything!
The weird thing is that it jumps to 99 without having anything running which implies that there is a background process thats eating up the CPU!

My cursor (not the mouse cursor) won't stay in one place. It jumps from field to field in just about every program I use, going from left to right, just like I'm pushing down the tab button on the keyboard. I'm on a desktop and not a laptop. It makes it very hard to type or to chose options in pop up windows. It makes the scroll bars move all by themselves too. I tried updating my keyboard driver without any improvement.

My mouse (cursor) is very erratic - jumps all over the place without warning, sometimes disappears for several seconds. I have to chase it around to bring it back in control! It is a laser mouse. I tried another one from another computer that I know works, and I have the same problem.

My computer jumps backwards on most applications. I thought it was internet explorer, but it happens even when I'm using Word. It acts as though I clicked on another area with the mouse when I didn't...most of the time I am not even touching the mouse.

when I am typing an email it seems that I can only type so much and then my curser jumps backwards into another part of what I've typed. It's done it four times now as I am typing this. Is it mail? Is it something else?

Trying to work out kinks on my Vista 32 bit. After clicking print in Windows Mail, it automatically jumps to an open Internet page, and then I have to click back to the Mail. This is driving me nuts.

I would like to ask you to Google for FileCopy/progressbar problem and see how Earth is filled with us - morons. My progress Bwr keeps dancing left & right, calulating time remaining (always lying by a huge marging unlike WinXP), but it's not too important. Important is that data transfer rate jumps from 16Mbps down to KBs periodically as it scans thru multipel files. All it can fast is copying a SINGLE large file, even that estimating time remaining and progress bar are not as good as in WinXP
This is one of the 500 admitted bugs Microsoft admits to in Vista and its a beauty. I hate to keep harping on the same point, but it makes absolutely no sense to me how such a basic function not just gets screwed up, but WHY Microsoft would ship Vista with such a obvious bug in it. It totally trashes their reputation. Oh wait, we're talking Microsoft. We know their reputation. Ship and fix later. Everybody knows whatever version of Windows we're talking about WAIT for the service pack before most of the bugs are out.

My main 'gripe' is if I am in Windows Mail, send an email - it sends, then immediately jumps to the browser, leaving Mail. I have to go back into mail. The system seems to have a mind of it's own. What do I do to get to STAY in Mail, rather than the window of the browser bounce back?

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)

After installing Vista Ultimate, I am experiencing problems with processes using an excessive amount of CPU. However when I run the task manager, and clicking on "Show processs from all users", I can't see which process is responsible since none is consuming more than a few percent of the CPU.My computer is obviously very slow and I haven't installed any program yet.

I think I have tried everything and I am not computer savoy enough to try some. But recently my computers CPU has been fluctuating a lot and has been pretty slow..I took off most of the start up programs and only have a few (virus software etc) but I was wondering if maybe it could be not by updating my drivers.. or bc i only updated some of my drivers.
I am currently running
4 gigs ram...
ATI Radeon HD 3200
vista 64 bit
professor amd duel core..

I've just had my computer for a few days and I've noticed that the CPU usage meter is at 60% all the time now (even when it's sitting idle).. where it was usually less than 10%. The realiabilty and performance monitor shows that something alled "LOCAL MANAGEABILITY SERVICE" "LMS.exe" is continually using 50% of the CPU. What is this manageability service and why is it consuming 50% of my CPU power?

When I am downloading my CPU is at 100% and as a result my computer slows down. I have AVG installed and have scanned my computer and have found no viruses or spyware. I have checked the task manager and there is a process called System - NT Kernal & System and it runs at 70% when downloading - surely this isnt normal.
