we need to know more about your wii.... sys menu and things loaded on your wii....

No need to pull the cord from the back, just press the power button for 5 seconds and the Wii will power down.

Download -- CB2_BB_SysCheck_1.6.1.zip

Backup and format your SD. Extract the files to the Root of your SD.

SD in the Wii , Click the SD Icon on the Wii menu -- Load boot.dol. Syscheck should start.

Paste the results here.
