Hi I was building my new computer, but after building it and connecting everything, I would turn on my PSU, but my motherboard would flash the lights it came with and just not do anything, my gpu would not light up at all and the fans wouldn't spin, the PSU fans didn't spin either. The RAM, lit up tho, and that was it. It just didn't post at all.
