Constant CPU And Disk Usage On Windows 7 64bit?
Sep 11, 2012
My Win 7 (64 bit) computer with a Intel i5 760 CPU, 4Gb of ram and AT Radeon HD 7500 Graphics card has developed a problem with about 25% constant CPU activity and constant disc activity. Task Manager shows that this is due to the "NT Kernel and System" process, and it can't be stopped. The surprising thing is that I get exactly the same problem in Safe Mode with no connection to the Network, so what the heck is going on?

I'm having a problem where windows utilizes 30% of CPU usage even when Idle.The problem starts when i open a program like games or any intensive application that requires alot of CPU load. But after closing the program, i noticed in my taskbar that windows generates and continues to use up to 30% of CPU load on other applications for example Dwm.exe (desktop windows management) but if i stop DWN.exe from taskbar, another program or service will replace it and generates the same CPU load, if i stop that another will take its place like svchost or the taskbar.exe itself getting a 25 to 27 cpu load. Its like an ongoing cycle or Loop of CPU usage, its supposed to stop after closing programs.I already have done steps i thought would clear this problem and these are:
Registry fix
ran Avast Anti-virus
reset BIOS
ran anti malware programs
ran Msconfig and disabled unwanted programs running on the background
ran windows 7 update
updated all my drivers
Summary:The problem still persist. This problem doesnt occur after boot, everything is fine with my system idle getting 97%. it only starts after i ran a program that utilizes high CPU load but after closing it, the heavy CPU load continues by replacing the closed program with another either dwm.exe,taskmanager.exe,svchost.exe..etc

I have a program that measures bandwidth and its reporting that I am downloading at full speed (1.2 mb/s ) all the time, and I think its accurate as my internet feels really slow. I double checked I wasn't downloading anything, and that all of the updates were on idle, but there is still traffic. What should I do? Also, I noticed a ridiculous drop from 250 GB to 217 GB of free space. The free space drop is gone, its showing 250 GB but the bandwidth is still a problem

Just got a brand new Samsung Series 7 laptop and everything was working fine until i started installing windows updates. The cpu is now stuck at around 15% load and there's constant disk activity too. I run msconfig.exe and disabled programs that I don't really use much, run disk defrag just too make sure the disk was working well. As a result my cpu is running hot (65 degrees) and the battery drains pretty quick.

Just got a new Acer aspire laptop for christmas. Everything works fine except that every time I turn it on or wake it up, there's about a 10 minute period of non-stop disk activity that causes every other application to come to a grinding hault.I downloaded process monitor and checked it out, and found the two most-accessed files are two TMP files called MSI7895.tmp and MSI8BDA.tmp, both in the Windows installer directory. No idea what either of these files are for.I'm thinking this has something to do with the tons of bloatware that came on this laptop. It's a 2.3 GHz, quad-core CPU with 4GB of RAM. I'd just really like to stop this so it doesn't take 3 minutes to open an Explorer window

I have a WD Green drive which parks its heads after 8 seconds of inactivity. This is measured by "load/unload cycle count" in SMART, and WD rates the drive for 300,000 cycles. I have accumulated over 15,000 in the span of a few days, which obviously isn't good for drive longevity. I don't have a way to run the tool provided by WD to alter the timeout for the heads, so I need to figure out what is causing this frequent disk access. Prior to whenever this started (I'm assuming it was a few days ago, when I installed a new motherboard) I was averaging 0-10 load/unload cycles per day, depending on how often I accessed the drive.I checked activity with Resource Monitor and found nothing accessing the drive except for the very occasional access of BCD.log and the MFT. However, I'm seeing ~3-6 load/unload cycles per minute, so something is accessing the drive every 8-20 seconds.
I tried using procmon. I set it to filter only for activity on E: (the drive in question) and I unchecked all the default "exclude" filters; I saw nothing besides procmon accessing the drive. I ran it for a good 5 minutes.The drive is connected to an Intel Z68 SATA II controller. I have no other drives which park their heads so I don't know if this activity occurs on all my drives or not. Again, nothing shows in procmon or Resource monitor. What can I do to see what's accessing the drive?Tried so far:Disabling SuperfetchDisabling AV
Disabling Indexing

So recently my desktop PC has been freezing at random times, and then sometimes restarting after not responding for a couple of minutes (no BSOD, just restarts as far as I've seen). It sometime freezes as soon as I turn the computer on, while Windows is loading, and sometimes it will start freezing after an hour it's been on. Most of the time it will just freeze for around a minute, and then unfreeze, but sometimes it does freeze and then restart. By freeze I mean everything, mouse included, and ctrl+alt+delete doesn't work.Also at bootup sometimes, it will fail to detect my SATA hard-drive and hang at Detecting SATA drives at the bios screen. This will be following by a disk read error.This problem started occuring a couple of weeks a go, so I reinstalled Windows 7 and it worked fine after that.

I have 6GB of ram installed on windows 7 64-bit ultimate. For some reason I'm noticing that the usage will rise past 50%, but I am unable to find all of the used resources. From what I found, I'm using roughly 3.2GB of RAM when I add up all the memory usage under the processes tab.

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

When I put my computer together, I decided that an 80 GB drive would suffice for the C: drive as the only stuff to be stored would be the operating system and programs.However, the size of C;Windows seems to grow without bounds - it is currently consuming 31+GB, which is simply ludicrous.

I am using Windows 7 (x64) and I am getting incorrect disk usage reporting through Explorer. I am looking at a 1TB disk, which with partitioning considered is showing as a 931GB disk - however even though I am using only 421GB of the disk space Windows 7 (Explorer) is showing that there is only 202GB free on the disk.As you can see above I selected all of the files on the disk, right clicked, selected Properties, and the results of my enquiry are shown (superimposed over the Explorer view).

I just checked my C: Drive for usage and it says that I am using 351 GB. I have 331 GB left, but I am curious as to where the usage of that amount of hard drive space is coming from. I hardly have any programs because of the clean reinstall and the current program sizes are no where near that capacity. The videos and pictures I transferred over combined it about 50 GB. Where is the rest of my disk space? I would like to clean my hard drive as much as possible. Restore points are also limited to using 10 GB as max. I have run CCleaner and Puran Defrag at least twice.

I have five Sata drives. Of these five, Windows 7 Pro 64 "Computer management" reports that two of them still are 100% free despite both having significant usage as reported in "Computer" and "Explorer"
F: Simple, Basic, NTFS, Healthy, Primary partition,
"Computer management" Capacity 92.21GB Free 92.21GB
"Computer" Capacity 92.2 GB Free 16.8GB
L: Simple, Basic, NTFS, Healthy, Primary partition,
"Computer management" Capacity 389.59GB Free 389.59GB
"Computer" Capacity 389GB Free 379GB
The L: drive is newly installed and only ebook files are on it. What might have caused this and can it be corrected?

I have installed a new W7 64 bit OS, plus a 32 bit (default install that I was unaware of) version of Office 2010. Everything appears to be working great except that I receive a dialog box request to insert Disk in drive/device 1v (It was 2 untill I switched two of the usb plugs.) I did notice that the OS sees my HP MFP as a disk drive.

First of all, I wasn't exactly sure where to post this problem, since I have been having so many (I think they're related), but I have been forced to reinstall windows twice now and the problems continue. The first time I reinstalled windows was only because I was having several problems with directx, file corruption, and failed windows updates. Some of my games would crash and give me errors referencing different directx files, and no matter how many times I reinstalled directx or the game itself, I kept getting those errors.
As for the file corruption, about every time I started my computer, it wanted to do a checkdisk, even after it had already done that and "solved" the errors.
The failed windows updates related to the .net framework 4.0 (Or something like that) causing the entire updates to fail every time I turned off my computer. For the most part I ignored this. So I reinstalled windows (first reinstall) and that seemed to solve those mentioned problems except for the checkdisk always wanting to run.
Fast forward a month to just the other day - I was actually FORCED to reinstall windows because it would not even boot up in normal or safe mode, and all my restore points had been deleted somehow. The problems started after I tried to install Terraria, which needed to install the .Net framework 4.0 to work. So once again, the .net framework was causing problems. I solved this by downloading some software that completely removed the .net framework (I think), and letting Terraria configure it itself. This worked, however after a couple hours of playing the game, nothing else did. I turned off my computer, and when I booted it the next day, windows wouldn't load. This is why I reinstalled the 2nd time. Now, I am having many more problems even after a fresh installation. I am getting all kinds of errors on corruption in certain files, my video drivers are failing to install, restore points being deleted, checkdisk is still trying to run (which I am letting it do), windows updates are failing, and both Chrome and Firefox gave me error messages like "Your profile could not be opened correctly" after I installed them. My 1TB hard disk still has about 300gb of space, so space shouldn't be the source of any those problems.
I don't even know where to begin solving these problems, so I am very tempted to format my hard disk. So my question basically is would just completely wiping my HDD and then reinstalling windows from scratch be a good idea, or is the problem beyond that?

I have done a clean 32 bit Win 7 install over a previous 64 bit install on the C partition. The D partition was not touched but now is inaccessible as is my external USB hard drive. Both are NTFS and up until yesterday had no errors or problems. It is a 64 to 32 bit problem or access permissions?

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.

I have 7, 64 bit, running on an HP and have been keeping pretty up to date on my drivers.amd a4 3300 processor with graphics card, and 4 g ram.When trying to use menus, the window or entire screen will seem as though it refreshes, closing the menu, i can watch the bar across the top of windows flash as if it had just disappeared for a split second and the menu is gone, leaving me to reopen it, but at a second or less between these refreshes I have to be quick on the pointer to get to what I want. It seems to happen on any menu item, including all drop downs, wether im right clicking a start menu pined item, a choice dropdown on a webpage, a setting dropdown, etc. it doesnt alwasys do this but more often than not. It seems like I can sometimes restart the pc and it will work, but it often will do it right at startup. I hadnt noticed it til I connected the VGA out AND the HDMI out to the same tv (dont know why I did it at the same time, I think to compare the cropping). Also, I used system restore to go back to before a bunch of updates and it seemed to fix it, but that might just be because the pc restarted in the process.

I am using my iPhone to try to figure out my computer. So it is the only one I have. It is in a constant loop of windows not starting and trying to fix errors then says it can't, I can't get it to load in safe mode or anything else. I can use the box where u put in commands and found my registry hive says 0 bytes. I do not know how to fix this. And I do not have a windows disk cause it came already installed. So how can I fix this and what do I need to do or try.
I do have a Windows 7 product key on the back of my computer.

I recently upgraded my existing PC with a new hard drive (WD 1TB Caviar Black), Windows 7 Ult x64, & upped my mobo to its max of 16 GB DDR3 RAM.I originally had problems after install with some of my partitions & hard drives not showing but everything worked itself out alright.However, now a new problem has cropped up, and I'm not entirely sure if its related to the original issue or if it is a whole new problem.Almost any program that I run will work for a time, but eventually stop responding. When I try to close the program, I will get a message from windows asking if I would like to end the process tree. This happens with everything, from Chrome to the League of Legends installer to Windows Explorer. If I hit yes, nothing will happen except for the "wait" cursor will appear, and my taskbar will completely disappear. It will usually catch up eventually, but I actually had to reset my computer during the LoL install, and Windows would not start up afterwards. I had to reinsert my Windows 7 disk and repair the installation.
Nothing I seem to do can fix this. All drivers are up to date, as are all Windows 7 updates. I upgraded from Windows XP, and tbh, at this point I'm regretting it.My system specs are as follows:[CODE]
