I had this question answered earlier concerning no power to MB. I've checked the jumpers on the MB and still nothing happens. I have a Biostar M7CND-A02 with 420 watt PS, 512 MB RAM DDR, 52X CDROM. This is a newly built system that I've done myself; however, the power was on earlier yesterday am. It never came back on around 7PM EST last nite. Everything in the case in brand new. I want to think its the mb before I go and get another. Also, my uncle placed an ASUS mb in the case and we never got any further than the post screen. Could it be the wires in the case itself that causing all of this and why didn't my uncle's mb work? Could it be the memory?
