okay so I just got a 1g stick of ram in the mail. its ddr pc3200. I was using 2 sticks of 512 pc3200 before. when I put one stick of 512 and one stick of 1024 in together it doesnt boot into windows, but if I just put the 1024 stick in it works fine. when I looked in the bios it said everything was fine. can anyone help me? the mobo is an asrock p4i65G btw.
