Windows 7 has High CPU Usage and slow performance

Hello all,

I've searched the forums, but was unable to find anything relevant.  I recently upgraded to Windows 7 from Vista.  It was running fine for about a week then all of a sudden everything started running very slow.  I checked the the processes tab in task manager and I am constantly running at 70-80% CPU usage.  I think this is very high considering the computer is only a few months old.  It seems like others are having this problem as well, but no real solutions.

I have turned off file indexing as well as disabled the HD audio device. 

Please help!

Here are my hardware specs:

AMD 9550 Quad-Core

64-bit

6GB Ram

Thank you in advance for your help.  I am ready to toss this thing from my second story window.

I think the answer might be the Windows Media Player and Windows Media Network Sharing Services as zxypher suggested.  The fix for that is to adjust were the Windows Media Player services search for media files. 

It seems to be a bad problem for me as well upgrading from Vista to Windows 7.  The default search location for media is set to C:\Users\ instead of down in the My Music folders.

Go into Media Player.  From the menu -> File -> Manage libraries -> select each library (music, video, pictures, recorded tv [if you have]) and check the paths that it is managing and make sure it is not too close to the root of the C: drive.  For example, it should be something like c:\users\Jim\Music and c:\users\Public\Music BUT NOT **** c:\users as they will cause the whole directory tree to be re-indexed over and over (when you surf the web or change any files in your profile).

If you have multiple users who login to the computer, you may need to repeat the process for each user if all users have added managed folders which are actively changing on a regular basis.

If this is your issue and you do it correctly, then the high CPU should drop in minutes (or seconds down to nothing).

This is the CORRECT way to adjust the WMNSS/WMPNetwk.exe process issues.

    Mine is a clean install. I have pandora one, firefox, and MS Antivirus running (plus taskman and Resource monitor).  And no, before anyone asks, MS AV is not running a scan.

    My CPU goes between 40 and 80 percent.

    I'm running Win7 Pro 64bit. Dual Core Intel CPU w/8GB of RAM.  Dell E6500.  Nvidia

    It doesn't do it all the time, but when it does, it just goes to ____ in a hand basket.

    I've monitored various aspects of the system trying to catch the culprit.

    From everything I can tell, it's a driver issue of some type.  Driver latency climbed through the roof (DBC Latency Checker).  My normal Latency is 500 or lower. When this happens, my latency is all over the place, spiking up over 4000.  DPC Latency Checker @ www.thesycon.de

    Anyway, it magically resolves itself. I've tried stopping services and just about everything else I can think of.

    It's so random. I've got the latest drivers, etc.

    As I write this my CPU has been fluctuating been 30 and 50%. Incredibly high considering what I have open right now.
