AMD R9 M275X

AMD R9 M275X not loading when I turn the machine on. Have to disable then enable for it to show it's working. Tried some games that were suppposed to work and they are slow as the second coming. I'm guessing it isn't working. Tried updating drivers, I get error code 174. This may be due to the recent windows 10 update... Having issues getting games to load before update. so want to throw machine off my balcony.
