    Thanks firebird,
    Your reference leads, even though not exclusively to a firm called QLogic (http://www.qlogic.com/pages/default.aspx ). Their home page shows a Support reference' but when I try to reach it, it's indicated and unsafe.
    I can't identify a reference to QLogig in my system.

    What did you do to your PC before this problem start?

    Have you installed new hardware?

    We need to know much more to be able to help you! The .sys file in question is a miniport driver from QLogik.
