Solved BSOD when shutting down computer, error 0x0000009f

[Chilly]

Please assist in finding the cause of the BSoD error when shutting down my PC (or restarting).
This is a relatively old installation of Windows with the regular windows updates.
I do not have system restore enabled so restoring to a previous working state is not possible as well as I do not have exact date on when PC problems started as it is running long periods between restarts/shutdowns.

I have attached the last 3 mini dump files, is this enough and or what other information do I need to make fault finding easier?

I have recently updated the following:
graphics drivers
network drivers
chipset drivers

It looks like the outdated driver for the SUNIX Multi-I/O Card is the issue. See if you can update it from the manufacturers site.

Note : I have seen many posts linking this driver with malware. I would run a full scan with ESET just to be safe.

Thanks Golden,

Agreed, these drivers are normally hosted on dodgy sites.
I will do virus and malware scan just to be sure as well as removing the card to see if problem persists.
