So about a month ago, my G75VW just shut off one day and I've not been able to get it back on at all. I started with replacing the power supply, then the motherboard, then the DC board(where the power supply plugs in at), next I replaced the RAM and CPU(incase they shorted out.) I'm still unable to get the computer to show a hint of life, no led's, no beeps, no fans. Nothing. I've disconnected all the other computers(usb boards, hard drives, audio board, etc) and still nothing. Any ideas what could be wrong and keeping it from showing like it's got no power at all?
