Lately I have been having a real big problem with my wii. To start, it has difficulties turning on. After several attempts, it finally succeeds. I mostly play ROMs on it, and when I go in to Homebrew and then in to SNES9XGX it loads fine but after 1-2 minutes (in games or even on the game selection screen) I get a lack screen with a bunch of hex code and it says it is dumping the memory. This then requires a hard reboot. I haven't changed anything recently, it just started out of nowhere.

Thank you for your help!
