high CPU usage cause by "devices not found"

Task manager identifies high CPU usage. Norton tool identifies 15 devices not found appearing as: Device TypeMpKsl3a07a498Device StatusDevice is not present, not working properly, or does not have all of its drivers instal...Plug and Play IDROOT\LEGACY_MPKSL3A07A498\0000Device TypeMpKsl9d4f8e3bDevice StatusDevice is not present, not working properly

Can not locate any of these devices. All drivers updated.

Task manager identifies high usage in AOL Browser, Deferred Procedure calls and interrupt service routines, NT Kernal and System. Etc.

Help appreciated. thanks,

Postponed IRQ's? First I would suggest running System File Checker while you check your Device Manager, and maybe even your Event Viewer.

To run SFC (System File Checker), open a command prompt. To do this, open up your start search, type in "cmd" (without quotes) and hit enter when you see cmd.exe in the search results. To run System File Checker as a command, enter this into the command console, and hit enter when everything has been typed in correctly:

To open your Device Manager, type in "Device Manager" in the start search, and click on it in the results. You'll want to look for any warning symbols under any of the expandable items in here. If you see one, please post what the error is showing up next to in your next post.

To open your Event Viewer, same thing, type in your start search "Event Viewer" and click on the item in the returned results queue that come up. In here, you'll want to anayze two different kinds of logs for any error messages or warning messages; Application, and System. These logs should be located under the expandable item on the left side titled "Windows Logs"
