CPU At 100% Task Manager Shows Nothing
Jul 5, 2012
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!

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.

Is this a normal Windows 7 error? I want to install League Of Legends but after I pressed yes to Administrator permissions to the program, then there is nothing, apart from Task manager says it is running, but I can not see anything on the desktop? I cant stop the program in task manager, which I think is a little weird?

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?

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

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). This is Hijackthis log :

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.

I've just noticed in the past two days that my Task Manager only comes up showing the Process screen. It does not have any controls for looking at applications or performance. I must turn it off with the taskbar window, close window. Does anyone have any ideas as to the cause and cure? I have used Glary Uitilities and CCleaner on the machine.

Task manager opens but it is an empty box with no data or tabs. I tried restarting the system but there is no difference. Update: Process monitor appears to interfere. Used System restore.

sorry if this has already been asked but i couldnt find a proper answer for me. I have 64 bit Win7 and i need to set my affinity to CPU 0 & 1 for a certain game that doesnt run well on my i7 860. I contacted them and they told me this is what I need to do. I do know how to USUALLY do this (task manager, go to process, show all processes, right click, set affinity...) but for some reason I cannot get the set affinity option to show up for the life of me.. also I am the administrator and I only have one account on this computer.

My windows 7 dell laptop hung on an application, no responsive desktop, no hitting start menu - nothing. I went to task manager and found NO Shutdown Option tab - I'm use to xp which had options under Shutdown, like restart, etc. So how do you shut down windows safely? I had to hold the power button until it turned off. On restart of course I got the dos window "windows did not shut down properly. Do you want to start in safe mode, or hit enter for the highlighted start windows normally

I have a Toshiba laptop with I7 processor. Occasionally, I get complete lock up: I cannot go to task manager or ANY other function. If I have music playing, it will continue and the monitor continues to display a still image.

i'm having recurring problems with PC freezing. I originally though it was when the PC went into stand-by, but turned that off and issue continued. Ctrl+Alt+del : get error message saying task manager not able to open, turn off using power switch. As nothing responds that is what I do. Checked anti-virus, and have run various scans, no problems reported. I have tried using different web browsers and the problem even occurred even when no browser open. Music continued playing until end of track. Have updated drivers, no overheating problems, PC 1 year old; MB: ASRock H67DE3; CPU: intel i5 2500; 8Go RAM; Windows 7 64-bits; ssd 64 Go (14.5 Go free); 1 To SATA 6Gb/s hard drive (840 Go free). Had no orblems until this last month. What proceedure can I take?

I've spent most of the night searching and cannot seem to find an answer to my problem.I have a NAS set up with two 2TB Samsung Spinpoint hard drives. The hard drives in the NAS were partitioned to have 300GB in a RAID 1 and the remainder in a RAID 0. One seemed to be failing so I removed it hoping I could connect it externally to my laptop and recover the data. When I hooked it up to the laptop, it seemed to connect fine but did not show in My Computer. When I went to Computer Management - Disk Management, it shows the partitions as healthy (see image - Disk 1). However, when I right click on the partitions to assign a drive letter, the only options available are Delete Volume and Help. Same when right clicking the Disk 1, all that is available is Convert to Dynamic Disk, Properties,

I somehow removed the controls on the Task Manager box. One section opens and the only buttons available are "show processes from all users" and "end process". Luckily, with no "close" button available, I can close it by right clicking on its menu icon and hit "close".

After Windows logo my screen turns black but i can see and move my mouse cursor, and when i press Ctrl+Alt+Del it works but the problem is there is NO Task Manager, it only displays Log Off, Change Password and Lock This Computer. I also cannot use System Restore because i dont have any restore points..
ive searched through the net all of them said that to fix this is to type eplorer.exe in Task Manager, but i was really disappointed because my Task Manager is gone.
Hoping for you guys not to give up on my case, cause all of the sites ive been through already gave up on me and stops replying

i'm new to this forum. My task manager is missing. If i press ctrl-alt-del, usually there is a menu that contain:
-Lock this computer
-switch user
-log off
-change a password...
-task manager
But now the Task Manager is missing! I don't know why! My computer is not just used by me, my brother and mother usually used it. I ask them but they said they don't know. Then is tried to search the task manager from 'start'. There is "View running process with Task Manager". I click it, but then show up a letter "Task manager has been disabled by your administrator."

I have a desktop, windows 7 ultimate. I now have a problem where when I enter my desktop it starts off completely black HOWEVER the mouse pointer is still there and can still move.After a few minutes the desktop taskbar pops up but it doesn't respond and stays like this. It's at this point where i decde to manually shut down my computer.I can ctrl+alt+delete but the task manager does not appear. I can enter safe mode.it might be a virus. It might be a driver problem but I didn't do any updates and I didn't do anything different.

when I load windows in normal mode, its really busy,whether im browsing or just trying to open up a file or folder, as in the blue circle item spins around constantly. I have left it long periods and it still hasnt done whatever task. I try to do control alt delete to end the task and it cant even load task manager However, in Safe mode it runs like a dream, no problems whatsoever, except that because the sound drivers aren't loaded its not much fun and want to try and get normal mode back.

I am attempting to change the look of task manager in such a way that the bars which indicate the CPU / RAM usage under the Performance tab are a rainbow instead of all green. I had initially thought I could do this by opening up taskmgr.exe with a program such as resource editor, editing the appropriate bitmaps (103, 104, 125), and then saving them.
Of course, when I tried to save, I ran into the classic "System error code 5: Access is denied" message. Same old same old. I took ownership of everything relevant already (I think...?)
So then I thought, why don't I just make a copy of taskmgr.exe, edit that one, change the bitmaps in there, overwrite the original file with the copy! This resulted in task manager not being able to load at all. In order to restore functionality, I replaced the new taskmgr.exe with a copy of the original from my desktop.
This makes me think that there might be some sort of hash function that wasn't checking out or something, but I don't know why there would be one.
