ok, so I tried it out of it's case and the power suply was the high pitch sound issue, it tested good on an other board... my ax45-v won't boot up at all if the 4 pin power is connected to the board, and it boots without it but it doesn't display video or read any drives, but the fan starts up... I'm just troubleshooting from my best judgement and common sense, but I'm at a point where I'm a little lost... I guess my next course of action is trying diferent cpu or different video card, wich I only have th one agp and the other video cards are pci and quite old... is there a better direction I should be pointed to??
