Hi, we need some more details. Did this start happening all of a sudden, i.e., it was working fine and then it wasn't? Or did you just install the card and the software for the first time and it's not working?
Go to the Early Startup Control menu (hold both mouse buttons while booting), and select Boot without Startup-Sequence. Then type:
set echo on
execute s:startup-sequence
You'll see the startup-sequence run line by line - where does it get stuck?
