I built my computer a day ago. I turned it on and the computer is powering one everything.
All the fans are working, there is power to the motherboard, graphic card is working. The problem is that nothing is coming on the screen. No message saying that OS is not found or anything. Monitor is in idle form. I thought it was the graphic card, brought another one and tried it (not working). Thought it was the motherboard and brought another one and tried it (same problem). Thought it was the memory (samething). Thought it was the cpu (samething). Its not the monitor. Tried different monitor samething. I don't know what's going on. Any computer genius out there help me.

The only thing you didn't mention changing was the data cable to the monitor. Perhaps there is a bent pin or something.
