Tascam FW-1804 detected only if power cycling PC (Win 10 64bit)

[MattP]

As title, my FW-1804 audio interface will be detected only if I power cycle the computer. Otherwise, if I simply turn on the sound card while I'm using the PC, it will not be detected. Restarting the PC or the sound card won't change anything. It needs the PC to be turned off and on again. After that the green firewire light indicator will turn on and the card will work just fine.

I know we're talking about 15+ years old FW audio interface on a modern Windows 10 machine and for this reason I've expected to be some issues, but I still wanted to know if exists some kind of solution for this.

Thanks

Update: Just power up everything this morning, now is not connecting in any possible way? Am I missing something with these units? I'm genuinely confused now.

Solved thanks to a gearspace user that had the same problem and replaced 10 capacitors from the power supply. These were the caps:
