You have done good job trying to solve the issue. I would try with another power cable, but it seems that there may be a hardware problem with your PC. Are there any noises coming from the computer, when you press the power button? Looks like the PC is not getting power. This may be caused by a power port problem or a motherboard failure. Have in mind that these problems are often repairable. I would suggest you to seek help from a technician.
