Thanks to you both for your replies.
I am pretty sure it's not the case; it snaps in just fine but when I loosen the screw (to the case) the card can wiggle back and forth about a 1/4 inch each way. Believe me, once I get it working I am VERY careful not to kick or bump the box in any way.
Nicos, what other info do you have? If its not too extreme I'll give it a shot next time this happens.
(If it hoses my board it gives me a good reason to get a newer one without too much drama from the wife
)
Thanks again, guys....
