Recently I've been encountering an issue where I'll be doing minimal tasks such as using safari with less than 4 tabs open. In the background I have photoshop open but not currently doing anything with. As well as aim and MSN and sometimes itunes. All of a sudden the whole thing slows to a crawl and I get the urge to throw it out the window. So i open the task manager and take a look and my CPU is at 100% (physical memory is around 30%). In the task manager i sort it so the highest CPU eating processes are at the top and they continue to jump around. for instance, safari might have 12 then 2 then 15 then 22 etc. I try ending a process that I'm not using and another process just spikes higher. if there is any drop, it's only down to about 92%ish. And it will behave like this until i close everything and start over.

I've never really had this problem until recently and the computer isn't that old. I bought it in May 2010. It's a HP G62-144DX with a 2.13GHz Intel Core i3-330M Processor and 8GB of RAM. My windows experience rating is a 4.2 with my processor and memory being a 6.2. According to speedfan, my temps average in the 30s to 50s degrees celsius.

Any suggestions? Is it possible that I've picked up some malware or something?

<<Is it possible that I've picked up some malware or something?>>

Of course, it's possible...but "possible" covers an awful lot of things that aren't factually true in a given situation.

Can you post a screenshot from Task Manager which reflects this high CPU usage, as reflected on the Processes tab?

had to wait for another spike but I knew it would happen sooner or later. here are three shots to reflect how it jumps around every second

It seems to be some kind of system process hogging the CPU when I'd think it would be photoshop or sony vegas, but they are usually practically nothing in comparison.

http://www.whatisexe.com/process/mcchsvc.exe.html, I would uninstall McAfee and use Microsoft Security Essentials as my AV.

Svchost.exe processes can be a number of things...if you want to see what is running under svchost, then take a read at:

I think mcafee installed with some software I got recently. If I'm not mistaken, it was doing it prior to that. But I'll uninstall it and see if it helps. I read something about seeing what service it is connected to and stopping that service when it spikes I'll try that the next time it does it.

More than likely you accidently installed McAfee Security Scan during a Java update (the most common place I see that download added in). The real problem here is that your AV (Microsoft Security Essentials) and the McAfee baseline scanner are both consuming large amounts of CPU. MSE is not the most efficent/fast antivirus on the market, and you could cheaply replace it with something much better. If you are a Comcast internet customer, they provide Norton Security Suite for their subscribers at no cost, which provides a free and infintely superior experience compared with Microsoft Security Essentials. Also, Norton software runs with one of the lowests resource footprints of any AV on the market while not sacrificing on protection and not harassing you every few minutes.



If you really want to be sure about the McAfee software being removed, try this:

Go to Start ----- > Run and type appwiz.cpl and press enter

This will open App/Remove programs (Programs and Features). Uninstall all McAfee products and restart your PC.


download and save the MCPR (McAfee Consumer Product Removal Tool) http://download.mcafee.com/products/licensed/cust_support_patches/MCPR.exe


If you are running Vista/7, make sure to run it as an administrator.


If you want to remove MSE in favor of a better security product, follow the instructions the same except use the MSE removal tool (should you encounter any issues removing it) which can be found here:

so I'm still having issues but this time the culprit is the audiodg.exe file

so I'm trying to use camstudio to capture my desktop to create a tutorial in photoshop. These two programs, along with a couple of tabs of firefox, were the only programs I had running. I had even closed all of my IM software. Now I expect camstudio to use up a lot of CPU but while it had half, the audiodg.exe had the other half.

I googled it and found a hotfix for a memory leak with the audiodg file (it happens sometimes where I'm playing music, it lags and the music comes out all alienlike for a few moments until the cpu is freed up a bit) but is a cpu spike the same thing as a memory leak? I wasn't sure.

I'm going to test on the desktop to see while doing the same actions, if the audiodg file spikes on another computer. And it doesn't jump up abnormally high (goes from 00 to 02 to 03 and back to 00) but the desktop window manager goes up to in the 30s (dwm.exe), but still not a constant 100% that causes the computer to lock up. Camstudio will range in the 30s and 40s but I expect that.

Did the removal of McAfee help?

That process is a Windows 7 audio driver when you player any music files. Showed up on my system as a Local Service http://www.neuber.com/taskmanager/process/audiodg.exe.html

No, it still spikes. I'm at my wits end here.

Some of it I figured could be related to firefox so I created a new user profile and disabled the plugin container (since it eats a ton of CPU). It's better. However, getting that under control, let's say I were to go watch a youtube video that lasts more than a couple of minutes. About midway, things start to get a little sluggish and my audio get choppy. I look in my task manager and the process that is eating all the CPU (remember, firefox plugin container is no longer there), is relating to audio. After I close out of the video, after a few moments, things go back to normal.

I did as instructed here, however it seems to have not made a difference. I've checked my drivers and they all say up to date.

I found a hotfix for an issue relating to audiodg.exe from microsoft, but I wasn't sure if I should try it. It's located here. My physical memory is never an issue and hardly goes over 40%. It's my CPU that is driving me up the wall.
