After I see the Xbox splash screen the screen goes dark with the circling (waiting) icon, but it takes a long time to load up after that before dashboard is displayed. Someone told me I was hacked because everything started slowing down. Also, I am unable to update my games, it looks like it wants to download but then it gives a msesage stating it can't and this code 397F-0000-D080-0200-8007-045D. Everything I try is slow, getting on xbox live, playing multipy player games, sending messages all move slow now, very slow to the point I don't want to use it.
My network connection is fine. Any help is greatly appreciated.
