noob needs help

I have 2 wiis and one has the 3.4u and the other has 3.1u. I have tried to install hbc on both with no luck. I have wads to install but have not been able to get the wad installer to work on either one. the 3.4 freezes up and the 3.1 resets but i dont have the hbc on it and cant play any wads. I have a 1gb sandisk formated with the format tool. so my question is what do i need to do to get this to work i have tried everything to a t and still have no luck. any advise would be apreciated.

More than likely you are using an unofficial, unsupported and thus illegal wad of the HBC. Install the HBC normally (twilight hack and HBC boot.dol in the root of your SD card) and you'll be fine.
