Sound card issues

Hello i have a computer which is running windows xp professional version 2002 service pack 3 AMD phenom ™ 9600B, quad-core processor, 2.30GHz, 3.37GB of RAM.br
i am using ableton live 9 with a komplete audio 6 native instruments sound card, when i use the ANA vst on many of the presets the CPU usage in ableton maxes out at way over 80%, do i need a better computer or sound card? as i am unsure how to resolve the problem as i am new to ableton and digital music production.br
Any help or advice would be very appreciated.

Hey Mark, this little free program helped me solve a lot of my problems. Sometimes bad drivers cause this sort of problem.br

thanks again that one worked and it says This machine should be able to handle real-time streaming of audio and/or video data without drop-outs. so still non the wiser on how to resolve this problembr

Does it happen with any other VSTi’s or just ANA?
