my wii bricked suddenly was perfectly okay the day before

my wii bricked suddenly today. power button takes a few times before turning yellow.
after it powers on, i see a flicker of flash and then black screen.

i turned the power off and then restarted it again and it got to the multi mod manager screen but then i couldnt get my wii mote to work. i am at a loss. appreciate any kind of advice and help to fix it.

read on several forums that it could possibly due to a faulty bluetooth module or even wifi module. but i am have a feeling it could just be a corrupt file or bootmi.

if it's gonna help the last thing i did the night before was played some videos on mplayer ce and then i shutdown from homebrew straight. my wii mote batt was kinda dying though.

thanks for reading all!
