  • Explorer.exe - high cpu usage

    Hi,
    Since almost a year (since a windows update or program install, i can't recall it) I am fighting with the following problem:

    Explore.exe consumes extremely high cpu (typical 25-40%),
    See: http://dl.dropbox.com/u/6437966/procload-high.jpg

    Without running the file browser, processor load < 10%!
    See: http://dl.dropbox.com/u/6437966/procload-low.jpg

    Diagnose:
    When I start the server with msconfig set to "Safe Boot - Minimal", problem disappears!
    (So the Server HW itself is OK)
    When I start the server with msconfig set to "Diagnostic Startup" ("Load basic devices and services"), the problem is already there again!

    Pls help someone to find out what causes the issue.

    Server: Dell PowerAge SC1430, Xeon E5320 1.86 GHz, 5 GByte RAM, X64

    Installed programs: http://dl.dropbox.com/u/6437966/installed.jpg

    Installed updates:

    Thanks for any help in advance!

    Create a new user and login with that account. Does the problem continue? If not then it is a bad Windows profile.

        Use msconfig to start each service in order to determine which service is causing the issue.

              If you have been fighting it for a year, it may be time to format and reinstall

                That should be the last option. No thanks

                  So go into the services console and start the services individually.

                  Check your minimal services required to operate then start adding them one by one until the problem re-appears.

                  Personally i'd look at removing your AV from the server to start with.

                  Then i'd remove Adobe Reader, Mozilla Firefox, Radmin Viewer, IrfanView, UltraVNC.

                  Its a server and i wouldn't install any of these apps on one.

                  Another thing to check is that Adobe updater is not trying to update from the internet. I've seen this chew resources, typically the Adobe updater exe file though.
