What is QLFCOEI.SYS and how do I solve a 0X0000221

Hi,
My win10 pro system with the follow (see pic) error message.

I tried to find QLFCOEI.SYS so as to identify its identity' but failed. I can't locate it.
What's wrong?

A google search turns up many hits.

Here is one:
What is qlfcoei.sys ? | System Explorer

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.
