well i got 2 MDD's (1.25ghz DP and 1.25 Single processor) i've been trying to get at at least one of these to work but i just can't seem to figure it out. they both do the same thing and only thing i can think of is is that the ram isn't compatable. they both start up and seem to run (no chime) and after about 10-15 seconds the fans go max speed? this happens with or without the ram installed so i think it might be tied to this? i've tried both pc2100 and pc2700 and neither seems to work. i sure hope it's not the processor or motherboard . i've searched but couldn't really find anything that could help. if anyone knows anything that could help. thanks.
