What POST Codes were displayed just before the 0x1C POST code appears?
estava normal 00 depois deu 40 ai agora antes de de aparecer o 1c aparece 1e depois 1C ai desliga ai fica ligando e desligando .
I hate to say it, but these codes indicate that the BIOS is unable to properly initialize the Peripheral Controller Hub component (PCH, essentially the chipset). The system cannot operate without the PCH component working properly -- and this is why you are seeing the system being powered off shortly after you see these POST codes. Since this is an indication of a hardware component failure, you likely are going to have to replace your motherboard.
