hey guys. i hope anyone one can help me on this one.

i don't know why but my cpu is reaching 100% load while im not doing nothing... im using vista ultimate edition and i use a gadget to monitor the cpu usage, and it fills out 100% on every core. im using a Intel Q6600 @ 2.4GHz.
but when i open the task manager, the cpu usage drops down to normal again... but when i close the Task manager, it goes up to 100%.

i don't know why it does this, is it because of a windows update? cuz yesterday i wanst having this problem. i was planning on instaling CRYSIS, and the windows recommended an update (before i could play the game i must download the update) so i did, i left the computer doing the update.. and today when i instal CRYSIS, i see that i have a problem with the CPU usage...

can anyone help me plz? i just don't know what to do ..

tks in advance

Did you format the drive when you installed vista? I didnt the first time either and I had the same problem.
I ended up re-installing vista (did a complete format this time) and the problem went away.

this is not the first time that this has happened to me... its the second time.. the first time i formated the system partition and instaled windows again.
my dad had the same problem. and he did something to make it go away but he doesnt remember.. do you have any other suggestions besides formatting?

tks

1. Press ctrl+alt+del to run task manager, there you can see what app in particular is running the CPU at 100%

2. If you can't get to the bottom of it that way then un-install the update. Do this from control panel, programs, view installed updates

Reply to notherdude

tks .. ill try that.. i really appreciate it =)

Reply to flash_mz

nope.. i tryed ctrl+alt+del but when i do that ... the cpu load goes down so i can't see if it's a program that's consuming it...

and i un-installed the last update before this problem and it still persists =(..

anymore suggestions?

Reply to flash_mz

Try shutting down any suspect programs, such as that AVA search for example. Maybe it's stuck in some sort of indexing loop. Shut down all running programs one by one until you hit the right one.

I'd also scan for spyware. Try another free one such as adaware if spybot doesn't see anyhthing.
Also try shutting down Kaspesrsky.

If all else fails try a system restore.

i tried to shut down the programs and the problems still persists... im donwloading ADAWARE now... what do you think the problem may be?

Reply to flash_mz

Not sure. Hard to say until you narrow it down. Something is running. Either a program or some windows process. Could be virus or spyware or it could be something simply malfunctioning, either hardware or software.
Try booting into safe mode (press f8 after startup, just before windows starts to load) and see if it is happening there.

Reply to notherdude

Another idea: start task manager, highlight 'explorer.exe' and then 'end process'. Now, still in task manager, go to file 'new task (run) and type 'explorer' and hit enter. See if you still have problem.

Does the PC seem slow and unresponsive during these 100% episodes? Is it happening all the time and after every boot?

Do you still have the windows old folder? If you do, then that means you didnt format. It caused me problems even when I deleted the folder. There was some kind of conflict, even loading a webpage was 100% cpu usage and dog slow. I couldnt deal with it anymore. I formatted and the problem is now gone.

I had a similar problem which seemed to be a running battle between UAC(User account control) and Zone Alarm. Could try disabling UAC and see if that makes a difference.
Also check your power managment options as my Q6600 was being throttled right back, and seemed to be using an excessive amount of processing power.

instead of alt ctrl del, try ctrl + shift + esc, this goes striate to the task manager instantly so might catch that rogue usage

I'm thinking whatever program you are using to monitor CPU usage may not be working properly... So another thing to do is try a different program to monitor CPU usage.

Great point. I should have told him to look into this at the outset. I think he's gone now though.

Reply to notherdude

hey guys... im sorry for the delay i was on vacation without any internet available... im gunna try out everything you said
ill keep you posted

thanks =)=)

Reply to flash_mz

my UAC is disabled and i downloaded a probram to see the cpu usage and it still tells me that im using 100%.
when im on safe mode the cpu usage is normal.
the strange thing is that when i use the task manager, the cpu usage goes down to normal.

the pc seams a bit slower with the 100% usage...

i have no ideas now =(

Reply to flash_mz

the program i used to see the pc usage is called ''cpu usage viewer'' its a freeware.

what are your suggestions on programs for catching spyware or viruses... i always thought that KASPERSKY could chatch any virus =S... hmmm...

Have you tried the above suggestion?

Try turning off the sidebar.

Try turning off aero.

Kaspesky is very good but in these cases it's always best to try several anti-malware programs. Try the free online versions. Adaware and spybot and AVG all have free versions.

You also might try running 'hijack this' and then post your log.

I'd also update all my device drivers if that has been awhile. Particularly your video and audio drivers.

Also, in task manager turn off ALL running processes and programs which will allow you to turn them off. Try to get your system running with almost nothing running in the background. You can't hurt anything turning them off. Even your anti-virus, just unplug from the internet/network when you do.

So it is clear dnetc.exe is the problem. I also see it in the hijack log as : O23 - Service: distributed.net client (dnetc) - Distributed Computing Technologies, Inc. - C:\Windows\dnetc.exe

I am not familiar with it myself but a quick Google seems to indicate it can be part of windows update, part of legitimate distributed computing projects like folding at home, AND part of illegitimate distributed computing viruses and worms!

On my Vista ultimate 64 I have no dnetc.exe anywhere on my c drive! Hmmm..

Have you installed any distributed computing projects like folding or seti? Assuming you have not:

1. Try turning it off from within the window that pops up when you ctrl+shift+sec. Just highlight it and select 'end process'. Does it then stop? Does it stop and them come back on? Or what?

2. Click the windows button/orb in lower left desktop and in the box type: "msconfig" and then hit enter.

3. Click the 'startup' tab and see if dnetc is in the list of programs set to start up automatically. If it is then deselect it and reboot and see if you still have problem

4. If dnetc is NOT in your startup list then something else is starting up and then running dnetc.exe. So list all of the things in this startup list and perhaps we can figure out which one is the bad guy.

5. If none of this helps you may have a deeper sort of virus and we can cross that bridge if we get to it.
