thanks for the reply das stig....already tried a new hdd and both got power(spinning) but still not showing up in bios. i cant swap out dvd because dvd is ide only and hdd is sata only. i tried swapping sata cables/ports, checked bios config, and even reset mobo by taking battery out/in and still not showing up. i see 4 empty sata slots in bios. every other piece of hardware shows up fine. the only thing i didnt do is update bios. is it possible that just the sata ports burnt out? also, if the dvd ide port works, can i use a satati ide adapter for my hdd? (f.y.i this is main hdd with o/s) thanks again.
