Hi. Welcome to the forum, the DUC. (It used to be known as the Digidesign User Conference, a long time ago. Hence the duck in the top left corner.)
I think you need to provide a little more info if you are to get any useful input. Like:
Your PC. OS? Specs, what type of connections does it have?
Do you use Pro Tools or other software?
What type of work do you use it for?
Budget, more specific?
What exactly is not working for you now?
