My PC stop sending signal to the monitor. It starts but dont make any sounds, no even show the startup screen. I´ve clean the RAM and check the CPU but i dont know what else can be causing the problem.

Hi @genisaro , Have you checked that the monitor is working (try OSD menus) and that the monitor cable is OK? Is the CPU fan working? Are the keyboard lights on? Check if you have a “speaker’ connected to the 4 pin connector next to the RAM (see image). If none there then connect one, if you can That way you might hear “beep” codes which may help to find out what is happening, (or should that be not happening) if it fails to pass POST.
