Possible that the card ould be the problem but doubtful, however make sure you have the correct drivers installed for it.
Check the pulse width is correct for your drives in motor tuning.
Could be the parallel port is just putting out 3.3volts and the old computer is 5v. If thats the case possibly your breakout board is not happy with the 3.3v. If that is the case then you could get a PCI card that puts out 5v or get a breakout that is happy on the lower voltage.
