Here's another thing you can do that is free.
Clean the edge connector on the toaster cards with alcohol and swab.
Then clean the gold connectors inside the video card with a fine cloth, saturated with alcohol folded over an old credit card.
Most Amigas are over 15 years old now that these connectors get dirty.
Okay....it's probably unlikely that this is the cause of your problem, but it MIGHT be, and it's a good thing to do anyway.
