About two days ago when i got on my 360 slim it made me download an update before i was able to do anything else on my system. at the time i thought nothing of it being that i get system updates from time to time, so i thought this one was a normal one. Once the update had finished and i began to use my system it was running super slow, and then it came up with a screen saying that the system had either something corrupted on it or it was missing an update and that it had to restart. so i restarted it thinking that it may have not fully downloaded the update. then it did the same thing this time sooner then before, and it made me restart again.so i gave it a day hoping that it would fix itself. It didnt, so i cleared everything off of it and re formatted my memory unit and it is still doing it online and offline. does anyone know what it is that i need to do because all i have right now is an expensive paper weight!!!
