Rundll32 Windows Host Process - High Disk And CPU Usage
Jan 4, 2012
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

I recently re-formatted my hard drive, and noticed an icon in the task bar called "windows host process (Rundll32)". I looked it up and it said it could be malicious. I'm not sure if it is or not, but I ran Malwarebytes and nothing came up.

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 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.

I have Windows 7 32 bit on my laptop and Windows 7 64 bit on the desktop, both Home Premium. Every time I go online with the desktop it starts a download according to NetLimiter. The download appears as Host process for Windows services and it expands to process 720 and then to 92.122.126.243:80. I use 3G mobile broadband for my net access and this download could use a considerable amount of my Gb allowance. Using NetLimiter I can kill the download but I would like to know what is happening and do I need the download? Some idea of the d/l size would be handy as well. None of this happens when I log on using the laptop.

To keep my computer running quick, I usually skim through my processes at boot up and see what can be trimmed off from the starting processes, or just from my computer. Host Process for Windows Services shows up twice on the list. Right now at 125,080k and 75,476k memory. I don't recognize these processes or why they are using so much processing. Any advice for tuning those down or speeding up my PC in general (it automatically runs defrag, disc cleanup, standard accessories, etc. once a week).

I get an error message 3-4 times daily saying that the windows host process has stopped working. I am using Build 6956. I am doing normal things that i always do like build web applications, searching the internet, and writing a word document. It appears out of no where. I have attached a screenshot of the error message.

I have a problem but i bought a new Dell laptop with the following specifications:
Dell Inspiron 15R
core i7 3.1GHz Turbo, 6MB cache
16GB DDR3 RAM
Geforce Gt525 1GB Graphics
Now the problem is that when the system is ideal it takes around 2.5 GB RAM usage. Even there is no running applications. Also I noticed that it's performance not that much. Is it normal?

I reinstalled my OS (win 7 x64 ultimate). After that I launched my favourite game (lineage 2) and when I logged in game i experienced some freezes and lags, so I looked to task manager and I saw that l2.exe process eats like 40% of cpu per on window, my cpu isn't strong, but before reinstall it ate like 8% of cpu. Whats causing that game started to eat like 5x more cpu then before reinstall? I thought it can be caused by some drivers which might be installed with some other games in past.
Specs:
AMD Athlon 64 X2 5400+ Black Edition
Gigabyte GA-MA770-UD3 (rev. 1.0)
Gigabyte ATI Radeon HD 4670 512MB DDR3 GV-R467D3-512I
I have newest catalyst installed and also i have amd dual core optimizer.

I'm having a problem with my CPU after I did a clean installation of Windows. Any time I put my CPU under any stress, major or not, my CPU runs at 100% and makes my whole computer slow. It can be little things such as launching a program, navigating though my files on my computer, taking a screenshot or opening and running Chrome. It can also be major things such as running games, such as Terraria which I could run at 60 fps all the time before my install, but now can only run at 2 or 3 because my CPU is at 100%. I know there are not processes that are running extremely high, trust me I've checked, and also when my computer is idle it goes down to 20-ish% or rarely down to 2% I was running Windows Ultimate 32 bit previously and decided to upgrade to Windows Ultimate 64 bit so I can run my 64 bit only Adobe programs. I bought a 2TB external hard drive to put my files on and an extra 2GB stick of RAM.
I did a clean install of Windows and noticed that my CPU ran at 100% (I had not installed any drivers instead of my Graphics Card, Network Card, Sound Card and External Hard Driver). I though it might have been a dud install, so I reinstalled 64 bit a second time. This time I installed all my driver for every component in my computer, but again 100%. I decided to go back to 32 bit, however it lagged so bad I couldn't even reach the login screen. I decided to give 64 bit one more chance. I installed all drivers and essential programs, but again like I've seen so much, 100%.I decided to go to Windows 8 64 bit Pre Release. The first time I tried to install it, I tried keeping all my apps, settings and personal files, but my CPU ran at 100% so it took 6 hours and failed at the end. I tried once again, but it failed the same way. I then burned the ISO to a disc and did a clean install of it. Again, the same problem arose and my CPU runs at 100%.

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.

I have an ASUS K53E with Windows 7 Home Premium 64 Bit. The issues I'm experiencing CPU usage sky rockets to 100% at start up. The only programs I have installed are Google Chrome and Audacity(a free audio editor(lightweight)). I purchased the computer less than 6 months ago. It also freezes constantly. I took it into Best Buy 2 weeks ago for tech support. They stated that the memory and hard drive are in working order through their testing. I have also ran tests and found the same thing. They stated that the issue is Windows 7 and they wanted $200 bucks to fix it, but they didn't tell me the specific problem.
-I've restore the computer to a repartition twice. Still froze.
-I've ran CCleaner and othe registry fixer-uppers. No go.
