The only time I had such a problem was once when the card was 
really overheated. It worked again after it cooled down for a while.
Only tuning was affected (playback worked). So, it probably is the 
demodulator which stops working (hence the tuning errors).
I only had this problem once and I had 2 cards in slots next to each 
other at that time.

Do you have an old card (1.3) or one with a new tuner (1.5, 1.6, 2.1)?
I think the old demodulator created more heat. They were even
connected to the tuner casing with heat conducting paste.
