thanks for all the help, i tried switching around the ram to diff slots, and only using one stick, etc...no no avail. all the fans do turn on when i press the power button. and ive used XP pro since the beginning with no other OS installed. im 99.99% sure everything's plugged in properly. There's no 4-pin molex alt power supply on the mobo, so i know im not missing that. other than that i have the cpu power plugged in, the 24pin main power, the gpu power, all the fans, HDD, and dvd drives.
any other suggestions?
