Hello. I recently bought several sticks of second-hand RAM for an 8.5-year-old computer, with a Foxconn motherboard. There was nothing wrong with my old RAM, it was just that it was only 512 MB. When I put it in I evidently didn't seat it properly as when I switched the PC on it gave repeated, long beeps. I reseated it so that it clicked in, but still the beeps. I tried each other stick that I had and still it beeped in the same way, even when I put my old RAM back in, so it seems that the reseating hasn't been recognised. Can anyone help me with this?
