I have a Wii that is a couple of years old that I am having problems with - there have been no mods done to the system at all. The Wii was working correctly though had not been hooked up for the past month. When I went to set it up today, black screen only even though power was on and you could hear the drive. All wires are connected correctly. I unplugged the Wii from power adapter for several minutes and initially it would freeze at the Health and Safety screen with no option to Select A to continue. After unplugging it again I was able to get it to the main menu but when I tried to go to Wii Settings it brings up a black screen stating that the system files are corrupted and to refer to the Operations Manual for troubleshooting. Any suggestions on what to try next - if anything?
