I am having a problem with my mother board the asus M4A77TD.
I have 2X2gb DDR 3 1333MHz modules. when I install one of them the PC runs fine but when I install both of them it does not boot only the fan and HDD runs. I tried all combinations of ram slots and did not work.
I tried each ram alone and it works so no problem with them, the only problem when they run together.
I have athlon x2 260 CPU.
