Asus — laptop is working slow

Address: Mumbai City, Maharashtra

one month back i bought g551jk dm053h. even though it has got 4th gen core i7 processor in it, its working slow. From day one only felt it was slow i thought its performance would get better with time but it did not. earlier i was using acer emachine which has got core i3 in it. this laptop tranfers file in usb or harddrive very much faster than this asus laptop i m using.and this asus notebboks sometime even laggs.my laptop serial no. is EAN0CJ01299641H
