Hello! I have a problem with an old motherboard D845WN, it run with 256mb ram. I inserted SAMSUNG 512MB PC133 DS SD RAM and it beeps 3 long (I have 2 of this single and pair in same beep, nothing on the screen,just the winchester led on).I tried another 512 MB RAM its SS(SDR 64x8 133/P4 512M AUM 4009) and the same 3 beep.I change the videocard and the same 3 beep. On the homepage of the motherboard it can runs but it can't !! What is the problem and what can i do?
3 beeps means no memory, so either the memory is faulty or it is not compatible either with the motherboard or between modules. Try each module on it's own see what happens
