Will a Barclaycard Visa help me in building up credit score?
Payment history is probably the most significant contributor to your credit score.  Having a solid history of making, at least the minimum, payments on time will have a positive impact on your credit score.  Whether or not this specific transaction means anything to that equation is up for debate.   If you have no credit lines now and 0% for 18 months on a computer makes sense to you, then yes, making this purchase this way and paying on time will have a positive impact on your credit score.  Paying interest doesn't help your credit score.  Repay this computer before the 18 month period ends, then be sure to pay your balance in full every month thereafter.
