What Plaz was trying to explain (I think):
If your A1200 works without the Blizzard installed
and
with the Blizzard you get a black screen it's probably the cpu (68060) contacts on the card. The 68060 probably has a cold solder contact that needs resoldering. The problem may not even be visible as it could be under the 68060 itself.
If you're not good at de-soldering such a big chip and resoldering it; send it to Amiga Centre in France (Jean Jacques Boulet can do it for you).
