My acer ax3400 4802 desktop has a power problem. When power switch is pushed, fan comes on, but not boot up or blue light. After many pushes, power switch got blue light and boot up. Now I want to replace the switch, but don't know where to buy it. It appears to have 3 sets of 2 wires each coming from the switch and attaching to a plug on the mother board. Where to buy acer cabinet parts? Thanks for any help!
