Hello,

I'm William Cigic and this is my first post. I'm not sure if this is the right place, but I ordered a pre-modded wii with a wiikey2 from modchipcentral.com and I updated the wii's firmware to 4.1u. My wii perfoms all functions fine, but when I play a backup of a game (at least zelda: twilight princess), the wii will just power off after a couple minutes to maybe a couple hours. I have to remove the power cord from the wii and plug it back in to get it going again. When the machine does power down, the power led is also off. Any idea what may be going on?

Thanks
