Hi, can someone please help me. I just built a computer and when I tried turning it on, the monitor does not show anythign. All my components such as graphics card, CPU and fans are working. I also checked the plugs and they are in the right place however there is no sound or anything that shows on the screen. I read a post which said the motherboard is broken however I hope this is not the case as I only bought it yesterday. Can anyone please tell me what is it that I am doing wrong?
