check that the mb bios is up to date. i dont know if i was looking at the same board from biostar but the bios that i looked at were for cpu code update. (version 7x ) http://www.biostar.com.tw/app/en/mb/introduction.php?S_ID=536&tab=3
if it not the same mb then check that the sata ports are set to achi not raid. if the mb and cpu have video and your also using a gpu..pull the gpu let the system boot and install the drivers it needs for the mb and onboard video first. once the mb drivers are installed and the video drivers for the onboard gpu. power down and install the gpu. then boot into the bios and make sure the gpu is set for the first video device and onboard is turned off. one other thing to check is that you have the mb and ram speed and timing set right. check that the ram is read right you may have to change the ram speed or voltage. two things to check is the cpu and ram been qal on your mb.
