hi. I have a big problem.

my wii doesn't work. when I try to switch on, I see some words in a black screen but I can not read that bcause of the words not clear. It is like "the sytem files are corrupted...." I'd like to fix that but I can't.

I started my wii with sd card than I installed HBC and bootmii than I tried to restore my wii from NAND backup but it did not work. It says "press a+b+x+y" but it doesn't work. just start,reset and eject buttons work in that screen.. how can I do?
please help me...

-restoremii v0.6
-in the bootmii info ; ios 60 v24.30
If you need more please ask me...
