Monitor no signal but pc is running

[Helpme1235]

Hello, i built a pc a year or so, now my monitor is literally black screen with keyboard and mouse not lighting up but the pc works as well as the cpu and gpu fans inside the system. However, my motherboard doesnt show yellow light anymore when my pc starts. Is my mobo causing the problem? I recently bought RAM so it cant be that. i checked all the wire and tested with different hdmi and vga cables still it says no signal. i reset the cmos battery but it didnt work. i dont know what parts is causing the problem. help thanks!
