Much as I hate to suggest shotgun debugging, if at all possible, it's almost certainly time to start swapping the individual components out with known good ones. I don't have any experience with BIOSTAR motherboards, but I would start with the RAM, as it's most likely to be that which is crapping out. What brand is it, or is it generic?
