Just listing the components isn't helpful. When you turn it on, does ANYTHING work, such as fans and such? Have you verified that you plugged the power supply into the correct headers/plugs? If it doesn't even turn on the power supply fan, have you checked if the power supply circuit breaker / fuse hasn't tripped / blown?

I have built a lot of systems from components, but many people have problems doing so because they don't utilize due dilligence in making sure that all the i's are dotted and t's are crossed properly.

I have plugged all of the cables in. The fans start working but no display shows up and the speaker dosent beep at all.

It's the problem in Motherboard. Does the indicator (power/hdd) blink? if it does, the motherboard needs to check or replace

Try changing the power supply. The right amount of power isnt going in to power the computer up.
