Hey everyone,

I'm not positive if this will solve the problem you all are experiencing but I did find a solution.
I was playing a game and I started having the max cpu issue and the game was lagging out. A thing I noticed was that the sound was all crackly as well. I opened process explorer and found that audiodg.exe was hogging all my cpu. I looked it up and they said to turn off the sound enhancements to cure the problem. I did this and it solved the problem. I haven't had issues since.

To turn off sound enhancements, right click on your volume control, then go to playback devices. Select your main audio output device and click properties. Go to the enhancements tab and check off "Disable all enhancements". Or you can fiddle and tinker around to find out which enhancement is actually causing problems.

That is not going to help i assume as it did not help me, i would like to ask if u were playing online or no? because after reading every ones post i only see the problem happening when some app is using the net.

Now i am trying to install Windows Vista n then going to up grade it to Windows 7 n not clean install W7 so lets see what happens. I have 2 laptops so will try n update as much as possible

It made no difference whether I was playing online or not. But I know for a fact my problem was with audiodg since after I turned off the sound enhancements, my problems went away.

Well guys i installed vista and then windows 7 over it, TO my notice it was a useless thing as i realised that The Windows Updates are causing of CPU usage problem. Only thing i have to figure out is which update is causing the problem... will start fresh in the morning n try to figure that out. IF some one wants to start early Can uninstall their updates n try n figure out which one is the cause LOL.

I have a familiar problem. It occurred when I tried to play an mkv file. The cpu goes to 100%. I looked at the processes and found out that explorer.exe is responsible and uses 89-97% of cpu!! The problem stops once I log out and log in in my account (or restart).

CPU was at 100%

Hi there

I realise this is an old thread, but after Googling my problem this was the most useful thread I found, in my opinion *is* still useful, and it helped my solve my problem (it appears).

I had similar problems as described just recently with Windows 7 of CPU at 100%. For example, my Windows Media Player Network Sharing Service was hogging a lot of CPU, also saw Task Manager at way high CPU whilst it was open, had Firefox and some other applications maxing out the CPU for no apparent reason, I've also seen the HD Audio process hogging CPU. I stopped many Services and disabled a number of items from startup.

In the end, the problem seems to be because I had recently changed to the 'High Performance' power plan, which in Control Panel > Power Options > Select a Power Plan > Change plan settings > Change advanced power settings > Processor Power Management > Minimum Processor State > Plugging in (which is what I have most of the time), the setting was set to 100%. So it seems that this setting is causing my CPU to *overwork* somehow (seems silly to me).

Changing the Power Plan to 'Balanced' seems to have fixed the CPU maxing out problem...! Yay!

So I wanted to share it on this thread as it seems to have helped a lot.

Cheers
Matt

Hello,
I got this off the Microsoft website and this works!
So, first goto start and type msconfig.exe (or just msconfig).
Mext, go to the startup tab and disable some services (except microsfot services.)
