to echo the point on the PSU - you NEED a more powerful PSU for this card. I have an A1200 with a Microbiotics 68030/50 with (if memory serves, been quite a while since I used the computer - sad) 32mb RAM in it - I used to get all sorts of quirky (non-fatal) problems with it until I upgraded the power supply - then voila, rock and roll.
Before tearing apart your card, RAM, etc. etc. - get a higher power PSU and test first. It likely won't be cheap these days - but it is certainly the simplest solution and likely the optimal one.....
a stopgap (NOT permanent!) solution may be using an A500 power supply - I believe those had slightly more power than the A1200 ones, even though they otherwise look fairly identical.
good luck!
