Hi, One of our PC, attached to laser stamping, start to show (Windows 7) startup failure. It start repairing but at end message appear, can not repair. We installed new windows on other PC and attached again the disk but again same message. We changed the hdd with fresh OS installed but no hope. The hdd work on other PC ok but not with this motherboard. Also it do not go setup of BIOS. BIOS is Amercan Megatrend. Is this problem solve able or only need to change the motherboard.
