razer blade wont turn on issues with usb port

i would like to fix my razer blade laptop but it had an issue with the usb port didn't work at times and then it quit working all together and it had issues with turning off when you shut it off it go black but the green light would stay on and what happen was when you leave it like that it would heat up very hot and then it show a red light and i turned it off one time an i forgot i didn't shut off an what happen was it mostly heated up so hot that it broke a part i was wondering if i could get help fixing the problem or would i just have to get it repaired.
