I am experiencing when my power supply is plugged into the vms4.1 i get the crackle popping noise. but it goes away when the power supply is unplugged. I have replace the power supply with a new one and the noise still persist. but only when the power supply is in use.

thank you for your reply. it is currently plug into a adp power surge unit. and what do you mean ground lift??? currently i am using only usb power which is working fine.
so as i stated before brand new power supply same result as the old power supply crackling sound as soon as i plug it into the vms4.1. if i unplug the power supply the crackling noise goes away.

On one hand it sounds like a latency issue - you have the VMS4.1 ASIO buffer set too low. This is a common cause of pops/clicks.
On the other there may be a ground loop issue, which is why ground lift was mentioned.
You say you're using a VMS4.1 but also mention a Creative card. Which one is crackling?
If you're running VDJ on a laptop, try unplugging the laptop PSU (running the laptop on battery). Does the noise stop?
Have you swapped the VMS4.1 USB cable for another? Have you tried using another computer?
