My Wii takes forever to load programs, and when I hit the Home button on the WiiMote, it not only takes forever to return to the Wii Menu, but it also loses connection with the remote. Could this be a sign of an nearly-bricked Wii? And if not, is there a way to fix this?

Some programs also won't load, and I have to end up unplugging my Wii because it freezes up. D=
