Explorer.exe Using 50-100% Cpu


I've noticed this for a few weeks. In task manager, explorer.exe shows as using 50-100% cpu, and programs seem to run more slowly. This reliably starts when i open an "explorer window". It will also start if i use msconfig to disable everything (except microsoft services). I have booted into safe mode and run malwarebytes anti-malware - nothing found.

I then ran process explorer, and discovered that the thread which seems to be responsible is called (has a start address) nttdll.dll!Etwtracemessageva+0x130. There may be one or two of these threads present, each using 48%+cpu.

I believe these are responsible, and i think they are used in some kind of event logging, possibly a debugger that somehow got turned on, but i don't know how to proceed from this point.

Dumprep.exe Causes 100% Cpu Usage

Whenever a  program is "not responding", i'll hit "end task"in "task manager", then another window opens up with a choice to select "end now" and it'll take forever for it to terminate. Meanwhile, i cannot do anything else as task mgr shows 100% cpu usage. I notice dumprep.exe is causing the 100% cpu usage and i can only wait until it completes whatever it is doing. Most often, i'm waiting several minutes. I'm not sure what started this problem as in the past i never recalled this happening.

Cpu Goes Up To 100%

I have upgraded from win xp to win 7 , with cpu intel celeron d 2. 53 ghz, 1gb ddr2 ram, nvidia geforce 6200 , via vt8237 sata , via rhineii lan and cmedia cmi9761 ac97 audio codec. After updating most of the drivers individually from the different manufacture , the computer become better in performance, however, it is 4 % cpu when idle and 100% when opening any one of the programs , such as word, ie8, etc and doing virus scan by kaspersky.

Notice that , i can not complete the virus scan as it shows messages insufficient memory after 3 hours scanning and then stops the scan. Also , the cmi9761 has no drivers updated for windows 7.
Do not know whether the single core cpu is the problem or the 1g ram is not enough.

Cpu At 100% Usage

I upgraded from vista to win 7 on release day and have had no problems until recently. Over the last few days, my cpu usage will spike up to 100% at random intervals and stay there for a long period of time. When i check task manager and show processes from all users, services.exe is fluctuating anywhere from the low 50 to low 70% in usage. When the computer is running normally, services.exe is around the high single digits. I've uninstalled and programs that i installed immediately prior to the problem happening (and it's happening again as i type this) and i've run comprehensive virus/malware scans using microsoft security essentials and the eset online scanner.

Both found some adware stuff and removed it, but no virus or serious malware issues. This has been going on for several days and has made my computer almost unusable, and i'm at a dead end for what to do or where to look next. I hate to to a reinstall because the original install was so recent, so any advice i can try to avoid starting over would be great.

Cpu Is At 100% When Idle

I have had a problem the last 2 weeks. My sons pc has suddenly started to behave badly when he is playing games. The are choppy and behaves strange. The same games worked perfectly before and just a few things has been altered. When i look at the cpu it's at a constant of 70-100% and it "spikes" every second. That behavior fits the problem it the games he plays.

When i look in task manager it shows that wmiprvse.exe has two processes running. One at 35-50% and one at 10-12%. At first i uninstalled avast 5 and reinstalled mse (the problem started about the time we changed the av) but it didn't help. I have also tried process-explorer and the only thing it tells me is several "ntdll.dll!Rtluserthreadstart" within wmiprvse.exe.

I have scanned the system for viruses and also scanned for malware but my system is clean. The system works fine in itself (windows 7 ultimate retail) but the hight cpu-spikes is really noticeable when a games is played. Of-course the system is up to date with all the latest drivers and updates from wu. What can i do?

Cpu Often Goes Up To 100% Usage

Often, i turn on my computer and it slows down a lot when i get to the login screen. It hangs on the "please wait. " Screen for a minute until finally letting me log in and then goes to the "welcome" screen and hangs for a minute more until it finally pulls up my desktop. The cpu usage stays at 100% for a while. Sometime it goes down to a normal level, but other times it will stay there until i restart my computer (which usually leads to the same thing).

I used malwarebytes' to check to see if i had any viruses, malware, spyware, whatnot and it came up clean. I defragged my computer and that didn't work, i looked to see if there was a program eating up the cpu and there wasn't and then i tried anti rootkit and that found nothing. So, i am pretty *** right now because i have yet to find a solution.

System Down Cpu Is 100%

I used xp and purchased windows 7, installed the 64 bit version and everything worked great. Then one day an important windows driver got deleted and there was nothing i could do but a clean install. I could not get the 64 -bit disk to read for some reason so i installed the 32. Now before the clean install, i could run two gaming windows and surf the net and my cpu would be around 30%.

Also when i rated my system my cpu was in the 6's. Now when i open one game window and nothing else, my cpu is 100%. And now my cpu is rated in the 4's. What could have made my cpu rate lower? I have downloaded the mobo drivers for windows 7 from my mobo manufacturer. I called tech support and think i got an asian kid that is still in high school. He did not have a clue as to how to fix it. I just did a clean install and he had me cleaning out my temp folders and other files which made my system unresponsive, once again had to do another clean install .

Cpu is still running poorly with windows 7. I have tried several things mentioned in the forums like disabling the windows media stuff but it did not work. The biggest thing soaking up my cpu is the system idle process which is always above 60%. I really like the windows 7 look but am close to just chalking it up to a wasted $140 and going back to xp. I thought windows 7 was supposed to be better than vista when it comes to resources but it seems much worse.

Cpu & Memory Usage On 100% Even With No Programs Running

My new laptop with windows 7 pre-installed is running slow. Task manager shows cpu usage and memory usage at or nearly always on 100% even with no programs running. Checked out various user forums and tried using the tools within win7, but no joy.

Spoolsv.exe At 100% When Loading Office 200

This prevents the office application from launching. Killing spoolsv.exe allows the office application to launch immediately. Spoolsv.exe response after a period and seems to return to normal levels. I have looked in c:windowssystem32spoolprinters for files, as per other posts, but that directory is completely empty.

When i ran office 2003 on the same computer the same issue occurred, even during installation. This is a perfectly clean install of windows 7 and office 2007. The pc is joined to a domain and a few printers are pushed out through gp at login. They are a sharp copies, hp lj 5000, hp lj 2430, hp lj 4200.

Wininit.exe Using 50% Cpu

My windows 7 dell laptop has recently become really slow. Cpu load is way up high, the fan is on full speed and the hard disk is very busy. Task manager shows that wininit.exe is permanently using 50% of the cpu with other processes mostly using no more than a few percent. In safe mode, wininit behaves itself and cpu load remains low. In fact i'm writing this post in safe mode because the computer is too slow to use in normal mode. I've run virus scans with avg and panda and both came back clean. I can't remember what i did, if anything, to make this start but i'd be grateful for any ideas on how to make it stop.

Taskhost.exe Is Running At 50% Cpu

In the last week or two i've noticed that at certain points (i think only when my laptop is plugged into the ac power source) my laptop fans start running loudly, which attracts me to notice that suddenly taskhost.exe (under the user name "local service") is taking up continuously 50% of my cpu power. This doesn't happen constantly, just a random sporadic occasions. The allocation of 50% will then no subside until i do a system restart.

Clearly windows shouldn't be doing this, can someone provide any assistance? I've read another answer here but that doesn't answer my problem - i've run a full system virus scan and cannot detect any virus present. (I'm running windows 7, 64bit, home premium on a 4gb 2. 4ghz dual core intel core duo 2 based laptop. )

Opening Program Will Start Run32dll.exe, Raise Cpu Usage

Opening an older program will start run32dll.exe, raise cpu usage, but not successfully start the selected program while running windows 7 x64. Up until this point, i have had no problems with windows 7. My system came installed with it, and i have recovery discs (although not with me right now, more to follow). I installed a program the other day and set it for win 98/me compatibility mode.

After executing the program, run32dll.exe would start and while cpu usage would go up to 80-90, the selected program would not start. Is run32dll corrupted (viruscan and anti-spyware programs run)?  Do i need to reinstall windows 7 (i have a valid product key, can i use someone else's disc and my product key)? Can i just get a copy of run32dll and drop it into the windows system folder?

**Yes, i know that i should have the operating discs with me, but i'm currently part of the haiti relief effort and didn't really have time to pack. I don't have access to them, and i'd rather fix this than use the evil restore portion of my hd.

Explorer.exe Uses Too Much Memory

My computer is running windows 7 home premium, 32-bit. I just discovered yesterday that my explorer.exe was literally chomping thousands of thousands of kb of memory just to run. (Going to task manager -> processes). Before, it would take, at most, about15, 000-17, 000 kb to run. Now, the only things i know of that are in explorer.exe are the background slideshow i had running, the gadgets, and the my computer/library windows i had open.

I have 1 gadget, a slideshow of 16 images, and two folder windows open. Before, i had 15-20 windows open and sometimes 40 slideshow images and 10 gadgets running at the same time and the memory still wasn't so high. This morning, it ate up 1, 432, 226 kb (1. 4 gb of memory) just to run. I was kinda scared, so i switched it to only one wallpaper, 1 gadget (the clock one), and no folder windows open. It still ran up to 125, 000kb. Does anybody have similar problem/solution?

I need more memory to make skype calls and use firefox. They keep crashing because i don't have enough memory. Even if i lower the priority of the process it still stays at a crazy level and actually, if i leave it be, it uses more and more memory every minute.

Explorer.exe Is Crashing

My system was infected yesterday by one of those fake antivirus programs. Usually i am able to get rid of it fairly easily. I run spybot search and destroy as well as defender. It seemed to have removed the problem. I restarted the computer and now i am having issues. Explorer will not load on it's own. All i get is a black screen with a mouse pointer in the middle. I used alt-ctrl-delete to start the wtm and explorer through it. But i am unable to open any folders.

After clicking on any folder it takes about 30sec for a message to popup stating: "server execution failed". I can start start most programs through wtm, but i want to run the disk check to see if there are errors. Is there anything i can do? Or should i reinstall? I would hate to do that, but if it's the only option.

Explorer.exe Stops Working

Double clicking on my computer icon usually displays the explorer page. In my case it hangs for ever and if you shut it down it displays the message explorer stopped working, resets the entire desktop and restarts. Same if i use the windows key + e. What is interesting is that i can see the contents of my computer using the link of my documents without a problem. I have tried turning off indexing, repair using command line sfc /scannow (as administrator) no problem found, and fix it for internet explorer. I would appreciate any help / advise.

Explorer.exe Freezes Constantly

I'm having a major problem with explorer.exe. After ~10 min. Of starting my computer explorer.exe freezes. No option comes up to restart, end, or wait until it responds like normally when a program freezes. I cannot open windows task manager when this happens (no ctrl+alt+delete, when i try to do this it doesn't open up). All programs become unresponsive (taskbar, start menu, web browser, game, etc. ). The only thing i can do is hold the power button on my computer and turn it off. Knowing that turning off your computer this way is very unhealthy for the computer i need to get this problem fixed.

Solutions i have tried (but failed):waiting for the "explorer.exe has stopped responding" box to appear (never appeared even after leaving the computer on overnight). Sfc /scannow (found all files to be ok) scanning for viruses, malware, etc. (I have used malwares bytes anti malware, eset nod 32, and superantispyware. None detected any malware, viruses, etc. )All of the solutions listed here system information:type of computer: laptop manufacturer: hp model: hp pavilion dv6700 os: windows 7 home premium x86 if you need any more info on the problem feel free to ask in the comment section.

Replacing Explorer.exe File For Themes

I downloaded a new theme for windows 7, however, i am nervous about replacing the explorer.exe file as instructed. By default, i would think that's a bad idea. But since i'm still learning my way around windows 7, i'm not sure if this is supported as i can't seem to find anything on microsoft's site saying that it's acceptable or not. Has anyone done this when installing new themes in windows 7?

Can't Open Explorer.exe, Control Panel, Or Help

Brand new windows 7 computer - can't open explorer.exe, control panel, or help. Can't see or save to c: or d: drives. Got the computer last night, and it worked fine. But tonight i can only access ie, media player, etc.

I only have the default user account at this point, so i have admin rights. I haven't really done much yet since i just got the computer last night. I was going to transfer files from my old vista computer tonight, but i can't even open up explorer on my new windows 7. I tried rebooting, but it didn't help. I also ran the sfc; it did not find any integrity violations.

When i click on the folder icon on the task bar, i get a dialog box with a heading of "explorer.exe" and a message stating "windows cannot access the specified device, path, or file. You may not have the appropriate permissions to access the item. " If i try to print a web page to xps, it doesn't commit the save on the c: drive (os and program files) or on the d: drive (data).

I have no idea why it is doing this! It is a brand new system. Last night i installed windows updates and changed the desktop background. I haven't installed any programs or transfered data. And it was just fine last night; this problem started when i turned it on tonight.

Services Explorer.exe Don't Work

I have windows 7 32 bit home edition installed, when i start my computer after logging in there is a message that says "c:windowssystem32system profile desktop not accessible, check user-name and password. " In the middle of the screen and my desktop is all black with no icons. In the lower right hand corner a bubble that says something along the lines of "could not connect to user profile service, this may prevent normal users from logging in" pops up as well. Anything i try to run either does not respond or says "the server process could not be started because the configured identity is incorrect.

Check user name and password.initially i did a clean boot and it brought back my desktop and allowed some programs to run (such as eclipse, skype, calculator and others) but i was still unable to get explorer.exe to run. However this no longer works although this functionality will come back seemingly randomly at times. The only thing i can think of to fix my computer is to re-install win 7 but i don't have a disk, i only have the download on my computer and last time my desktop came back i tried to run it but i got the "this service cannot be started" message. Safe mode works, there doesn't appear to be anything wrong with it other than the fact that it is safe mode and doesn't have full functionality.

I can't do a system restore as it seems i accidentally turned it off at some point and there are no restore points. I have tried sfc /scannow with no success. I tried looking for problems with registry keys but i haven't been able to find instructions on how to fix possible problems related to this in win 7 and seemingly similar problems in xp/vista don't seem to have the same structure for registry keys. Does anyone have any ideas as to what i can do? I'm at a loss and can't think of any thing else to try.

Explorer.exe Crash - Win 7 Pro X64

I'm having some problems lately with my windows 7 pro x64. About 2 weeks ago explorer.exe(the shell, not iexplorer.exe) start crashing without a (obvious) reason. A few days later i noticed that this problems usually but not always occurs when i'm using visual studio 2008. After explorer.exe crashes, every time i try to right click on the desktop or an opened folder, it crashes again. However this doesn't happen if i right click a folder(icon not inside the opened folder). Since this problem appeared out of the blue, i first suspected a virus or other malware so i did a full system scan with my norton 360 without finding anything. The second thing i did is to check every software installed short before the problems appeared. Except a few system updates the only apps i installed this month were metro 2033 and a video driver update. I removed the game and rolled back the driver to the previous installation but the problem persisted. Since after the first crash i can't right click anymore i checked every single non microsoft shell extension installed(adobe extensions, winrar, winamp, xnview, folder highlight, nvidia control panel, norton scan, alchool 120% and a few more - i know i have a lot of extensions but i never had a problem with this before neither on windows xp nor windows vista).

I also tried every single solution provided on this forum or any other ms forum or any other windows 7 forum i could find but nothing worked. Since i run out of options i replaced ntdll.dll and explorer.exe with the files from my hp laptop running same windows and 80% of my desktop apps(except games and drivers) but no effect again. The only thing i didn't do is to remove every update installed this month. I also performed a hdd test, ram test, vga test and cpu test and every thing is fine. (I had some technical problems with my pc so i ended up by changing my mother board and video card so i thought it's a hardware problem again). So, so far. Everything i know about this error is the info provided by event viewer and reliability monitor.

Here is the info provided by event viewer and reliability monitor:/*faulting application name: explorer.exe, version: 6. 1. 7600. 16450, time stamp: 0x4aebab8d

Explorer.exe Freeze Playing Logoff Sound

I want to take my machine in for service and want to be able to make sure the repair person knows what they're doing before i let them mess with it. I have had my dell xps studio 64bit for less than a month. Have installed minimal additional programs besides what it came with and when using explorer it has frozen on several occasions forcing me to shut the whole computer down and then displays this error with the only option to force the program to close. (Waiting for) explorer.exe playing logoff sound.

What exactly is wrong? And how can it be fixed? Thank you so much for your help. As you can see i'm very frustrated and concerned that i just spent a lot of money on something that is not working properly.

Multiple Instances Of Explorer.exe Running In Task Manager

There are multiple instances of explorer.exe running in task manager (currently 7), each one using between 10-40mb of memory. I've never seen this in any previous version, and it doesn't look right to me. Different explorer.exe processes are using cpu resources at different times. I remember reading a while back that this could be a sign of a virus, but i've done a full scan with nis 2010 and nothing showed up. Can anyone give me pointers where to start investigating?

I did a clean install of windows 7 last friday -formatted hdd and all, so there hasn't been much time for anything bad to happen!

Ram Usage Issue - 100% Running

Recently (2-3 days) i noticed that almost all my ram was being used, but no process was using it. As i use stuff like maya, with its known memory leaks, i was somewhat alright with it. Having restarted (ram was now free), the problem disappeared. Within about ~10 minutes, ram usage was at close to 100% with nothing (well, very little) running. Here is a screenshot of the problem:
http://img687. Imageshack. Us/img687/2259/aggfdaggfdfgdfgd.png

I then attemped to clean up my boot, and with odd results. It seems like the ram issue has abated (left it overnight running, ram was technically "free". Upon further inspection, the ram, whilst free, is under "standby". What would use this kind of memory? Nothing was running overnight except task manager and resource monitor. I've tried removing programs and services from startup, and the issue still occurs. Does anyone have any insight onto either the full ram usage or the ram standbys possible causes?
