First off my wii is modded with a wiikey2 and i'm currently using Softmii custom theme with 3.2u. My problems started this evening after work. I logged into the Check Mii Out Channel and it turned off instead. Then 5 min later it did the same thing, then again a few minutes later. It seems to do it randomly but usually after clicking a button and it fades to black and doesn't come back. I'm not sure if clicking is normal coming from the wii after exiting to wii menu but mine makes little clicks maybe 4 or 5 times right after the main menu loads up. But not every time. Sometimes only once when the greyed out empty channel screens blink on just before the menu loading. Then once more. But other times it clicks more times as if it's looking for something. I'm not even sure what the clicking might be or if it's common across all wii's. Earlier today I did install and erase several channels and have been trying out shortcut channels for apps residing on my SD card. Perhaps something got messed up during that process as they warn before use. Anyway, I had no issues before installing all the custom channels so I'm thinking that has something to do with it. If anyone has had similar issues with random shutdowns or knows what might be causing my wii to shut down and knows of a solution, I'm All Ears! Thanks for your time.
