Limiting CPU Usage Of A Process?
Dec 16, 2012
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.

my windows 7 has 4GBs of physical memory available tho it seems to often times only use about 3GB the thing is that as i use it, it will go above 3GB and then back down without me closing anything, what i figure its doing is limiting programs sense when this starts to happen programs like chrome will swap tabs to blank white pages and load up them vary slow, i assume this has be a memory restriction and it also makes alot of other programs tend open back up really slow and have random lag hick ups, thing is why won't windows just let them use the ram they need and fill the about 1GB ram i have left available ? also the resource manager says almost all the unused ram is on stand-by

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 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.

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
RAM: 16371 Mb
Graphics Card: NVIDIA Quadro FX 2700M, 512 Mb

Motherboard: Dell Inc., 076V94,
Antivirus: Symantec Endpoint Protection, Updated and Enabled
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 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:

I've noted that Firefox has an about:config (browser.download.manager.addToRecentDocs) setting that is supposed to make it not put the downloads into the Recent Items list (I dislike how downloads clog it up). However, it doesn't work.
If I open the download, then it won't show up but that's a poor workaround. The question is if there's a per-program method to determine what will go into the Recent Items list or am I up the creek without a paddle?

The software supplied with the CanoScan 9000F is limiting in the size of scan you can make. It limits the file size to 100MB. That is quite ridiculous in this day and age of 64 bit OSs, 16GB RAM, and so on.

I am getting this error all the time with Windows 7. I open a text file I want to edit, then go to save my changes and I get this error:"The process cannot access the file because it is being used by another process".I have full admin rights, running Win7 Ultimate x64 SP1. From a bit of research I have seen where many others have been experiencing this problem or something similar too. The only "fix" (that doesn't work all the time) is to close explorer.exe and then restart it to "release the handle"? Anyway, this is not acceptable for all the money and time I spent upgrading/configuring this new OS from XP -where I never had this problem- and seriously cuts down my productivity.Has Microsoft even acknowledged this as a bug yet? I can duplicate this scenario the second or third time I try to edit/save/delete a text file and I know that explorer.exe is the problem or a big part of it in any case. I don't want to go back to XP x64 but having to deal with this headache 10-20 times a day is just too much to ask.The file here is a game's map script & has to be saved to a .pk3 and then loaded into the program's root before it can run so i know othing else is running the file. No apps running in taskmngr either.

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 have had my laptop for around a year now, and it's always been pretty fast for a cheapish laptop, It's an advent modena m100 in blue, but recently it has started getting real slow, like my CPU Usage is at 100% all the time and my Physical memory usage is running quite high aswell, without even having any programs open.

When I first boot up the machine and start using it (win 7 ultimate 64bit) the memory usage stays arround 40%. If I keep using it, the memory usage will slowly increase until it reaches 99%. If I boot up the machine and just leave it there for a couple of hours, the same happens.I try to restart (via windows), it logs off, shuts down the system, the coolers keep spinning, the motherboard lights are still on, but it doesn't boot up again. It remains like that. I have to restart via reset button or power button.

My Audiodg.exe process is currently using 2,786,070 kB (not just normal bytes, kilobytes) of Ram. 2.66gb+ of Ram! I have searched the web as well as this site for any problems. My audio is working fine though... I have no idea why this using so much ram. Im guessing a memory leak of some kind... I restartand it starts off at a normal pace...

Installed Windows 7 over Vista with no trouble except when Windows starts a window titled "Desktop Gadgets" pops up with the following message:"Settings.ini is being used by another process. Close the other program...."The above results in having no sidebar or gadgets, and I have no idea what the other process might be in order to close it.

-At home, I want to use DHCP on my wireless network.
-At work, I want to IGNORE the DHCP address that the wireless network gives me, and force an IP address. Configuring the router to reserve an IP for my MAC is not an option due to a bloated corporate bureaucracy.
Right now, I have to go into control panel and manually configure the network EVERY DAY and while it's not all THAT much work, it's annoying.Is there any way to automate the process?

The Process Explorer display consists of two sub-windows. The top window always shows a list of the currently active processes, including the names of their owning accounts, whereas the information displayed in the bottom window depends on the mode that Process Explorer is in: if it is in handle mode you'll see the handles that the process selected in the top window has opened; if Process Explorer is in DLL mode you'll see the DLLs and memory-mapped files that the process has loaded. Process Explorer also has a powerful search capability that will quickly show you which processes have particular handles opened or DLLs loaded.

I've got a fairly recent Win7 x64 install on my system. Since Beta, I've been getting an error message "Not enough storage is available to process this command", which is accompanied by a stop code 0xc142 when launching items like Task Manager. I've seen the first error is typically related to the Windows Desktop Heap, but I've set from the original (2GB if I'm reading it correctly), to 4GB of space. I'm running a system with 1.7TB of available drive space (20GB on the OS drive as it's a smaller SSD drive) and 6GB of RAM. I've tried varying the windows page file from 500MB to the system-controlled 6GB with the same result.

When I don't touch my computer for a while, I get CPU 100% (or CPU 50% on this dual core). As soon as I touch the mouse, in one second the culprit escapes. I know it's something under svchost.exe and I know I could see which svchost with Process Explorer or Svchost Viewer. But since the whole process disappears as soon as I touch mouse, it's pretty difficult to pinpoint. Svchost Viewer doesn't list all the processes in one screen, scrolling is needed. So it's basically always hidden and I can't scroll to it as that kills the process.How do I find out what exact process inside svchost.exe is eating my CPU during idle? My goal is to prevent the offending process altogether from starting.By the way, which settings of Windows Defender can cause this CPU 100% on idle problem, I didn't yet try shutting down all the settings there.

First things first. Brand new discovery! Did you know that it's impossible not to backing-up and lose your old files during Windows 7 installation? That's right! Microsoft contradicting it-self in the first steps of installation preparation step by step information. At first they say that we should back-up our old files as they WILL BE deleted. Then they practically force an option of where our old Windows files will be backed up into Windows.old folder. So the folders such as "Users, Program Files, Windows ...etc" will be stored in Windows.old folder. And any other files created by you that are stored in "C:" directory will remain untouched! So don't worry about upgrading or backing up anything, since Windows 7 does it all for you! My advice, just go with a clean install and you'll be safer that way. Now back to business. Have you ever experienced a really bad day with such as Windows 7?Possible solutions for your headache have finally arrived:We need to try almost everything possible in our powers to locate and solve the problems, right?NOTE: I'm gonna do these steps backwards like if we don't really know how to solve this quick!

I am trying to install Windows 7 RC into to different machines. Both are self built machines. Both are running Win XP w/ sp2.
On one machine I have tried everything to get past a CD/DVD Driver request. The first DVD driver is a NEC ND-2500A. I found what I thought were the drivers, but whenever I get to the point of selecting the drive (with the drivers in it) they don't appear within the DVD drive.
I even went as far as to load the driver onto the HDD I am installing Win& to. After may attempts, with no luck, I installed a plug and play CD/DVD player. Now, I have never had driver's for this unit, but it still wants drivers for it.
What am I missing here? Why won't it get past this point. I have even gone as far as disconnecting C drive and tried loading directly to D drive (second HDD drive).
On the second computer it mentions something about an I/O shield problem and wont even let me get into the setup stage.
