Computer won't display anything on the monitor

[AILeXx]

Turned my PC on like normal and it boots up same as always but my monitor doesn't turn on for me. I've checked to ensure all cables where connected properly and even purchased a new cable to ensure that wasn't the problem. Monitor still won't turn on. *Solved* Had to reset CMOS

Do you see any visuals during POST? Can you verify your computer does completely turn on?
