Windows 7 has High CPU Usage and slow performance

Anonymous

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.

    Explorer.exe has a number of other processes associated with it.

    It's most likely a sub-process or application that's running in the

    background and taking all the CPU resources, which could be

    the cause of your PC running slow.

    To find and display what could be the problem try Process Explorer:

    http://technet.microsoft.com/en-us/sysinternals/bb896653.aspx

    SysInternals Forums: http://forum.sysinternals.com/

    Worth Reading: The Case of the System Process CPU Spikes

    http://blogs.technet.com/markrussinovich/archive/2008/04/07/3031251.aspx

    Once you have Process Explorer installed and running:

    In the taskbar select View and check:

    'Show Process Tree' and the 'Show Lower Pane' options.

    Move your mouse cursor over any column in the right hand pane

    and right click and check the following boxes:

    'Command Line' and 'Version'.

    Next expand the process named 'Explorer.exe' (click on the + sign)

    In the column on the left named 'CPU', look for any high CPU usage.

    Next click on the CPU column to sort the processes by %CPU usage

    (Highest to Lowest).

    Now move the mouse cursor over any process, you should see a popup

    with some detailed info.

    With the mouse over the process that's using most or all the CPU %.

    click on that process to highlight it, Now that  it's highlighted,

    right click and from the options listed select: 'Search Online'

    This should display what out there on the web about that process.

    You can also double click on any process to open up a more detailed

    'Properties' window.

    Note: some entries like Explorer, System/Services, and

    Svchost entries may need to be expanded to show the detail (sub processes),

    in this case click on the + located to the left of the entry.

    An alternate method using Process Explorer is to double click on the

    Graph located just below the Menu bar.

    This will open the 'System Information' window, which has a larger display

    of all three graphs.

    Move your mouse over any spike in the CPU Usage graph to see what

    process/application or service was the cause of the spike.

    You can also Double click on Explorer.exe and in the popup window

    select the 'Threads' tab, does any TID (thread id) have a high

    CPU percentage (displayed to the right of the TID #)?
