It indeed does to me! There obviously is something special with
this machine, I think you would do us all a big favour if you
tried to figure out what it is. For example just replacing the
power supply could be an interresting test, and it would be good
if you could measure voltages and ripple before and after
the exchange.

Above you also said:

It may not be a unique problem with this card, but it may very
well be a systematic fault with all those cards which makes
them work badly in an otherwise totally acceptable environment.

I think it is time for the this community to figure this out
and, if my fears/suspicions turns out to be right, take those
card producers in their ears.
