This is my first build and I went to plug it in and nothing happens. The only thing I can think of being wrong was there was not reset switch that I had to plug in where the motherboard showed in the manual. The other thing was a sprinkle of thermal paste got on the motherboard and I just left it there. I have tried unplugging my gpu and starting without it. Anything would be helpful at this point. The fans spin, lights turn on and it beeps too.
