it depends on your situation. for your average user, not so much.
now that you know what a motherboard is,

can you tell me how many usb ports you have?
the dead usb ports can either mean you have actual physically dead ports, or something is messed up on the software side.
im guessing the people you talked to already asked you to go to the device manager, so i wont say anything more
