Right where to start i've custom built a pc into my tv stand n it worked like a dream but the main fan was facing the wrong way anyway i turned it round and put it back n after doing so i noticed one of the wires to my power on switch had broken away i've tried replacing the switch with all new wire n switch but its just not turning on i've checked with a volt meter n both the pins and wires before the switch have power running to it, i've also pulled it all apart and checked for any parts shorting out the board but still nothing its like its just being stubborn
