I recently got a Wii off of ebay, it had no video. From what I know it wasn't modded. Well I fixed the video output, but it says the system files are corrupted after I click A on the startup screen. It runs in maintenance mode, and I tried formatting it there, but it kept formatting for about an hour even though there was only a few blocks of save data. Once I leave the settings the screen just goes black, same thing happens if I reset it. Any help would be appreciated.
