So going to cry if my Xbox brakes

Well, a week ago my xbox 360 pro worked just fine, but just 3 days ago it has started to do some kind of malfunction. First, the auto updates Achievements do has stopped working I seem to have to sign in to live after restarting the xbox to make them pop up now. Not only that but xbox live is trying a new update and it wont let you into xbox live unless you do it buut guess what? It wont freaking work. Apparently xbox live for how ever much of time was down some how at least for me >.<, but now I can't get onto live I still have to try it when I get home again but, if you guys know what happened or if I can fix it please tell me because I'm really going to be sad if I get the red ring of death and i paid 20 for no xbox live.
