I have a Lenovo H30 series desktop computer with Windows 10 Home Premium installed - when I can get to boot. When I power up the computer the power button lights up and the CPU fan runs but there is no indication at all on my monitor. I have connected a another known good video cable and monitor and there is still nothing shown on the monitor. There is also no 'beep' when the computer is powered up - it just plays 'dead'. I have tried re-seating the RAM module, video card and checked all the cable connections on the motherboard and hard drive. Any advice would be most appreciated as the computer is out of warranty.
