CPU Usage Spikes Tremendously For Low-End Process (Task Manager / Explorer)
May 17, 2011
System Info Utility version 1.0.0.1
OS Version: Microsoft Windows 7 Ultimate , 64 bit
Processor: Intel(R) Core(TM)2 Duo CPU T9900 @ 3.06GHz, Intel64 Family 6 Model 23 Stepping 10
Processor Count: 2

Now to the actual problem. The reason I bought all this RAM was so that the computer would run faster and more smoothly. Despite the large amount of memory, however, I still experience frequent spikes in CPU Usage, which I have learned is not related to RAM very much if at all. Regardless, I would still assume that my system wouldn't have to overexert itself to run simple tasks like Windows Explorer (i.e., folders, desktop and taskbar) or the Task Manager itself.
Either of these tasks, as well as others such as "System," "svchost," or "File I/O Surrogate" (none of which I know much about) can spike to anywhere from 30-70% of the CPU without warning, and when it does, the total CPU Usage ends up being 100, which REALLY makes my laptop sluggish and unresponsive.
I understand that RAM does not directly impact CPU Usage, but I would also assume that, since my laptop isn't ancient, that its CPU shouldn't struggle to display my folders/desktop/taskbar, or to run the Task Manager itself. I also run a daily virus check with Symantec Anti-Virus, so I don't think infection is the issue. In addition to that, I monitor memory usage alongside CPU usage, and the memory usage never goes higher than 10.5 (it usually hovers around 6-8) or so GB of my available 16-- insufficient RAM is also probably not the problem.

I have Windows 7 64 bit OS. However, under task manager the processes are showing: iexplore.exe*32, itumes.exe*32, etc. I've never seen this before. My computer is running slower, and has frozen a few times since I first saw this.

I've got a laptop with windows home premium 64 bit installed on it and I use it for gaming a lot. It's high spec and there's usually no problem but I've been having problems with guild wars 2.Basically the game crashes a lot. When it crashes, I end the application in task manager but if you go to the processes tab the process is still there and clicking end process or end process tree doesn't close it down. The game won't restart while this is hanging so I have to reboot the laptop. It's getting very annoying and is happening a couple of times a day. Does anyone know how to fix the problem? Is there a way to kill processes quickly or does anyone know what I can do to stop the crashes full stop?I've tried opening task manager and closing the application then closing down the process which doesn't work. I tried ending the process first before ending the application but that still closes down the application and leaves the process hanging. I've tried to end the process in the cmd line but it still leaves the process hanging or if I do it before ending the application it just closes the application and leaves the process hanging.

I've got this problem 2 days ago where my PC started slowing down and i've been getting random BSODs mainly "Special Pools Detected etc & Memory Management" When i start up the PC its slow and it takes alot longer to just open even a folder. I've tried searching for such problems and i've tried almost everything i know to try and fix this but i guess i'm still in-experienced when it comes to problems like this.It happened 2 days ago after i played an online game i got a BSOD and couldn't remember what it was. So i restarted and the problem started. The most recent hardware change was that i changed my RAM from 4gb to 8gb and nothing else. I did not install any new programs recently. So initially i thought it might be the RAM causing this problem so i changed it back to the ones i had previously. Here are the specs of my PC. [code]
Anyway i've scanned the PC using Avira, Spybot & Avast and there were 0 findings so i hope i am right to assume that my computer has not been infected with malware/spyware. But still in the task manager, the CPU Usage % and Memory Usage shoots up whenever i do any sort of action, eg. Refresh on the desktop, Opening a folder, Opening the browser etc. I've tried booting into safe mode. And the CPU usage was minimal compared to normal but i couldn't detect what was causing this problem. In the task manager, explorer.exe & svchost.exe were the top memory users. I've tried msconfig, disabled all the startups, but still i am having the same problem.

lies with a Acer Laptop equiped with a AMD Athlon 64 running Windows seven premium. Computer recently started acting slow after a Kaspersky Virus scan and virus removal. When checked in task manager, CPU usage remains at 100% or close after booting. Just simply trying to open any folder takes forever and CPU usage shoots and remains at 100%. The tricky thing for me is that Under processes, the calculation of processes being used doesn't add up to usually more that 20%, however cpu usage shows 100%. There are no inividual process that is being showed that is utilizing the processor. Virus scan, ccleaner, Malwarebytes and super antispyware doesn't show any active threats. Msconfig set to boot only the essential services doesn't fix. Safe mood work fine, so I kinda thinking it isn't a hardware issue

For troubleshooting purposes, I would like to have an app who can follow what IE is doing (his calls to register, opening and using activex controlers, etc...).
Is there anything out there specificly for IE ?

Out of nothing my CPU run at 100% and explorer was using 98%. I had to end task my explorer each time i try to delete files from desktop or when i refresh my desktop. I tried few ways including clean reboot (only system files running), clear temp data using ccleaner, scan using online scanner and vundofix (both didn't found any virus/trojan).

My PC is windows 7 ultimate 32bit OS! Few days ago I connected my pc with few friends pc to play a game via lan! After that day whenever I start my pc the start screen (desktop) does not show and directly my documents folder opens. When I close the folder a blank screen appears. Then I go to task manager n new task n then type explorer.exe, then it works normally !!!
This has happened every time I restart the pc. I downloaded MSE and removed the viruses that had corrupted the explorer file. Then I went to run n used the sfc / scannow command.... but nothing works and same old error i.e., no startup screen! How do I get the explorer.exe to execute on its own without always going to task manager! There is no other error in the pc other than that!

Looked in the task manager today and noticed 4 separate entries for explorer.exe / windows explorer. Is this normal? Or does it indicate a problem? Windows 7 32 bit system.

I am currently experiencing consistent restarting (every few seconds) of Windows Explorer on my PC. And this has caused the desktop to be unavailable/inaccessible. I'm desperate . To find out the error which is causing this, I need to access task manager (event viewer), which is also unavailable (greyed out when I right click on the task bar). By accessing the task manager, I hoped to stop the windows explorer process so that I can at least access to my school project. I cannot afford to reload the OS (Windows 7 Pro) as this will affect my school project.

In recent days, my computer extremely slowed down. A few months back, it started booting up really slow but I didn't mind it. It was working well, although if you opened a program too quickly before the system started, it would freeze. The fan is running full speed 100% when the computer is on. I ran Malware in safe mode, found one threat but didn't work. I tried services, turned them all off, didn't work.
One important thing to mention is that I can't type anything in explorer. If I open Menu Start and try to search for something, it will freeze. Same in explorer window. I can't delete a file with the DELETE key, I can't use CTRL+C, CTRL+V because explorer freezes. Right click works, though. I'm working on MSI FX603 laptop with i5 Intel Core, GeForce 425M and 4GB Ram. I just updated Graphics, Network drivers. No luck.

On occasion my physical memory usage will quickly rise form between 1 to 2 gigs of memory usage to over four until it reaches 98-99% percent of memory usage. I am running on 5 gigs of ram. This problem has even occurred while the computer was essentially idle. When this happens the computer loses almost all functionality. I've tried ending all non-essential processes to alleviate this problem but it makes no difference.

I have a Dell inspiron e1505. 2 gb RAM.
Essentially I am getting seemingly random spikes in my cpu usage where it ramps up to 100% and windows basically freezes for an extended period of time. Sometimes I simply have 1 google chrome tab open with no other apps actively running in the foreground and I get these cpu spikes. I just did a clean install of windows 7 to try and eradicate this and it persists. I am at a loss as to what the problem is. What is odd is even though the cpu usage spikes at 100% my available memory is almost always nearly around 50% still. So I am just not sure what is happening.
(unfortunately to no avail) High CPU usage, programs crashing, windows hanging - Tech Support Forum
Anyway like I said I eventually just did a clean install but the problem persists. Since the clean install I have not noticed and flash problems with chrome (as per the tech support forum thread) just random cpu spikes.

I have a problem where my CPU spikes to 100% while playing online games. When I check task manager there is no process that actually seems to spike. I have also tried a fresh windows install but this didn't fix the problem either. This only occurs while playing online games (starcraft II, league of legends), I tried offline games to see whether or not it had anything to do with the internet and I didn't get any cpu spikes at all playing offline games even though these games have higher performance requirements.

I have installed this game, Singularity. The game worked fine for a week then suddenly It would crash as soon as it was opened from the desktop shortcut. The game is patched to it's latest version, I have direct x all other runtimes and PhysX installed from the CD. The shortcut it set to run as Admin in compatibility. No matter if i try with the desktop shortcut or from the exe in the folder or from the shortcut in the start menu the game will crash asap. The only way this game runs is by pulling up task manager and selecting New Task then browsing to the games exe. Malwarebytes reports no viruses or any malware. Tried reinstalling, and it didn't help.

I am installing more RAM in my system, and want to monitor the page file for improvement/reduction in size and use. Other than performance monitor, can I see the page file in either task manager or resource monitor?

Some days ago I noticed after a couple of minutes I start mi PC, my CPU usage goes to a constant 100% , so I checked for viruses and such but MSE gave me nothing and neither Malwarebytes. Here's the weird thing, I checked the Task Manager to see witch process was causing this and it's always a different process (Sometimes MsMpEng.exe, sometimes dwm.exe and even taskmgr.exe itself) so I started killing processes like a maniac leaving just the few essential ones but nothing changed. I also stopped all the services with a delayed start, since the problem starts after a couple of minutes but the problem was still there. My system restore is disabled.

I want to run Folding at Home (FAH), but I don't want the FAH process to take up 100% of my CPU (6 core, 3.7Ghz) because it runs really loud and I don't want it to burn out the CPU and fan. Is there any programs I can schedule to run at login and silently limit it in the background? I found the program BES, but you have to re-configure which process to target every time you log in. I know I can change the Affinity of the process, but running BES at 50% runs a LOT quieter than running half the cores.

New dell n7110/win7sp1x64.At startup on new machine from dell, process explorer (procexp64.exe) lists 81 processes running (seems like way too many - compared to xp with maybe 25 at startup). But which processes I can turn off is a question for another day. OK, read carefully, at least 15 processes in PE show " Path: error opening process". PID, CPU, Private Bytes, and working set columns are shown for these "problem" processes, but nothing after that, ie, description, company name etc. For all other listed running processes (with known paths), all info is shown in all columns. The problem processes include some important ones, services, crss, ism, wininit, winlogon, that must to be working for the computer to work, and everything seems to be working properly, and no cpu spikes or other weird stuff is happening. Right clicking properties on these problem processes, properties window pops up as normal, but shows "version: n/a, build: n/a, path: error opening process, no command line, no current directory, autostart location: n/a, Parent: non existent process (708), user: access denied. Again, this info can not be correct since the computer is working. And then, after a few minutes, another window pops up and says PE has stopped working, and closes the program. Now, if this was the whole story, I would go to sysinternals with this, but read on... Task manager running simultaneously with PE lists 83 processes running, more processes than PE, and also ~5 different processes than PE, and PE lists some processes running that TM doesn't list. So PE and TM show different running processes at the same time. How can that be? For the processes that PE shows "error opening", e.g., crss, etc., when I click properties in TM for the same process, sometimes I get the usual/normal pop-up window listing the path, and all the other data as normal, suggesting the process is working properly. But sometimes when I click properties in TM for the processes that PE shows "error opening", I get no pop-up at all, nothing for that process. So, IMO, it's not just a PE glitch, something is actually wrong here. This is a new machine, with PE the only 3rd party installation. I have installed several dell driver updates, but this problem occurred before I installed them. Also, remember PE and TM simultaneously list some different running processes and TM also fails to show paths, etc.

I just a complete reinstall of Windows 7. As soon as my laptop started my CPU usgae is jumping between 0% and 100% continuously, with nothing extra running. I literally haven't installed a single program. I took a screenshot of the processes that are running by default, and also my laptop specs.

I have encountered a very high memory usage in one svchost.exe process on my win 7 64-bit. Attached screen shots of process associated with it. Some times it goes up about 300Mb too. I have tried several suggestions already available for this issue. But No luck. I've tried by updating Windows (ref), scanning PC by TREND officescan. Also when I tried with only with Microsoft Services using Selective Startup option in msconfig as suggested here, issue remains same. (With that can I conclude that it is related with malware?)
Also need to note that the WLAN AutoConfig service (wlansvc) associated with that svchost.exe make sense as I've encountered some problem uninstalling wireless router software.I feel that that has not been properly uninstalled. how to check/or rectify it.

I recently installed some new hardware into my computer.
Specs:
Gigabyte Z68XP-UD4
i5 2500k @ 4.5GHz
HyperX DDR3 1600
2x HD5870s
PC P&C 750W PSU
Crucial M4 64GB SSD (for my OS)
Everything went fine, computer performs top notch. But I'm having several issues (note, these issues happened BEFORE the CPU overclock also, so that isn't the problem).
1. Randomly (doesn't happen often), my computer will seem to lose internet connection. I'm hard wired right to my Linksys E3000, and it says that I'm connected, but no internet sites will load. Also, I cannot open the "network and sharing center". It just won't let me click on the icon in the task bar. And my CPU usage hovers around 25-30% when this happens. I downloaded and installed Process Explorer to see what the culprit was, and I noticed that of the 30% CPU usage, "System Idle Process" was taking up 75% of said CPU usage. It doesn't happen often at all, and restarting clears the problem up. But even though this SSD is lightning fast.
2. Smaller problem, but sometimes when I want to shutdown or restart, my computer just wont. It will sit at the "shutting down" screen forever and will basically do nothing, like there is a process in the background preventing it from doing its thing.

I have a computer that was running fine for a year or so, but now its been a couple of days and after an hour or two of use, it slows down and finally freezes. I don't know what it is. The clues I have include:
-I've run memtest86, no errors.
-I've scanned the whole system with 4 different virus programs, so not a virus.
-But I've noticed that rundll32.exe has been using a lot and I mean a lot of resources. After a couple hours, nortron tells me that it has high disk and cpu usage. I checked core temp, 100% on all 4 amd phenom 955 cores. I don't get it.
Specs are:
Amd phenom 955 be
4 gb crucial 1333
ati 5450
1tb hitachi hdd

Whenever I load up windows 7 with bootcamp, my cpu jumps to 100 % usage almost as soon as I log in. I can not figure out what is taking up my cpu power. When I open up task manager, there are no processes running anywhere near 100%. Also, when task manager is open, the cpu goes back to normal at around 2-3% cpu usage. WIthout task manager, the cpu gets hot fast and the fans start in full speed! Its insane! I play a lot of video games on my computer, and when I dont have task manager open, there is insane amounts of framerate lag. Games, such as Warcraft 3, are lagging my computer when they are set on low

BSOD: The session manager initialization system process terminated unexpectedly with a status of 0xc000003a (0x00000000, 0x00000000) I'm getting this on a shop system running Win 7 Home Premium 32 bit. The last thing I did was shutdown before going home and I believe it installed an update then shutdown, so I'm suspecting the update caused the problem.
I can't get into the F8 Safe Mode screen to try Last known good configuration so I think I'll try a System Restore from the install DVD. Does that sound like a good approach?
I don't have the specs with me but I think it's a 2.8Ghz Dual core Intel with 4GB RAM and two SATA drives. It's been running fine for about a year.

For the last few days I've been running some CPU intensive programs which I wrote. My laptop was getting really hot (70+�C), so I decided to blow into the vent to clear the dust out. However all this did was clog the fan with dust and it stopped spinning, so I used a safety pin to hook the dust out. The fan started spinning and it blew a load of old dust out, and my laptop is now running in the low 40's.
However now task manager shows the CPU usage as 100%, but when I sort the processes by CPU time, nothing is using much of the processor, firefox sometimes jumps up to 50%, but it doesn't stay there for long.Even when I boot into ubuntu, everything is still running really slowly.Also, speedfan reports my CPU speed as 600mhz, sometimes it shows a few other values (1400, 1200, 1800 etc), I have two core2 duo 1.83 ghz processors, so I wasn't expecting to see 600mhz!

Below is my HijackThis log file. There are too many apps on the task manager and I am unable to turn them off. When I kill a process, it immediately starts again (SearchIndexer.exe Connectifyd.exe etc., and I noticed that all are running as services). How can this happen? And more importantly is there a remedy[CODE]

Everyone I have Windows 7 Home Premium 64-bit and I have a problem with the task manager.The problem is when I try to start task manager it loads for like half a second and doesn't do anything. If I do ctrl+alt+esc it just selects an open program. I've even scanned for malware but I have noticed something weird when I go to regedit under Policies then System there is only (Default) and WallpaperStyle. I think a virus may have disable my account as administrator.
