After several monthes of flawless performance my Wii has stopped starting up. Everytime I turn it on, a black screen shows up with "Exception (DSI) occurred" and a code dump. I have a hardmodded launch Wii on 4.0U softmodded according to the stickied guide. The problems started a few days after last time I used the console (watched a film). Yesterday I turned the Wii on again and the error showed up. After turning it off & on again it passed both bootmii and preloader and went straight to the System menu but everything worked correctly from then on. Today it just straight up shoves the "Exception (DSI)" screen no matter how many times I turn it off & on, take out the SD card or pull the plug. Any advice?
