I know this thread is from last year, but I wondered if OP figured this out as I have near identical issue. I have a Firewire PCI card that showed the exclaim point and "could not be started" message but it disappears and reappears (sometimes working) depending on if I relocate my graphics card (AMD Radeon HD 7500) to a different PCI slot, or pull it and switch to on-board graphics.

Seems like a conflict of resources but I can't figure out any further. This is on Windows 10 Enterprise 64 bit
Just FYI... Getting your Nikon Coolscan to work on W7 x64 - Page 60 - Windows 10 Forums (sevenforums.com)

Point is I had one working on Windows 10. No longer using it now but I might be able to help.
