Yes, YES, YES!!  I have had this problem on BOTH an A500 and A2000.  Don't
ask me why, I guess it's a crappy socket or something.  Used to drive me 
bananas until I found out what the culprit was!  
 
What I eventually did that solved the problem, was to take the Agnus chip
out entirely, and clean/treat the pins with "Cramolin".  No problems since.

Cramolin is this incredible elixir that you can buy either as little bottles
from Monster Cable (as I did), or at electronics supply houses.  In the 
form I use, the red-colored liquid cleans and de-oxidizes the contacts,
and the blue-colored liquid coats and 'molecularly fills' the metal
surfaces afterwards.  I treated both the chip pins and the socket contacts.

Cramolin is amazing stuff.  Everyone who does _anything_ with hardware
should have some.

Hope it helps!
