First of all, I would definatley suggest just saying screw the darn thing.. The board sucks!
But if you're like me, you still want to find a way to do it if you can
So, I would first of all go to Biostar's Website- http://biostar.com.tw
and download the manuals for your M5ALA board and make sure all your jumper settings are correct before you trash the board.
It is a possiblity you may have moved a jumper by accident.
Then I would make sure and test the current components you have connected to the board, including the power supply.
If none of this works I would suggest doing as many other people have and smashing this POS Biostar mofoin board into oblivion and learn from the lesson.
However if you get it to start up, make sure you download the newest bios flash from pionex's website and flash the bios.. it is the ala0820d.bin flash.. I would highly suggest this..
Good luck in your Biostar misadventures!
