external hard disk

chyets

my external disk cannot be detected in my own desktop and i try out with my friend and the external harddisk can be detected in their computer. It is my computer problem or what? or because computer do not supply enough power to the hard disk? the hard disk is 2.5" and it can be detected before i install a new graphic card
