First look on asrock Bios IF the Hard disk is display, just press the F11 key on PS2 qverty keyboard, must shown the all drivers connected.
IF no one HD is displayed, the MS will never booting..
Open on bottom the HD and check if the powercord and sata cable are connected OR then open the MS panel and check this cables too ( maybe they have changed the HD...)

First have to booting from the HD and then if all is working again, start to upgrade the hardware.
let me know...you have also my skype ID if you need online help
