Having the exact same issue here. Nearly identical, except for the fact
that I'm experiencing it on Windows 10. I've tried Windows 7 as well,
thinking it was 10's fault, but with no success, as you might have guessed.
The card doesn't seem to be sharing its IRQ on my system, and it looks like
it spammed interrupts, as Windows was starting, until it was disabled by
the kernel. Again, this only happens with the official drivers, so there
must be something that they utilize that the generic drivers do not.
