I replaced the ram on my motherboard, and I used the layout that the manual indicated, 2 x 8 gb of corsair dominators, using the 2, 4 layout. Now when I boot my computer the screen stays black until it gets into the user screen selection right before your in windows, so you can sign in. there is no screen to push f2 or del. I tried pushing it and it does not go into bios. I thought maybe, if it is ok to used a different DIMM layout. or perhaps it is not my memory. anyone have any ideas please help.
