My computer won't properly turn on when there is four sticks of ram in it. Only when there is 1,2,3 stick(s) in the mobo in any configuration, but when there is 4 in there it won't work. I have cleared CMOS by resting the jumpers. That didn't work. I have tested the ram in another computer and it works like a charm. I have thought of so many solutions, but all to no avil. My motherboard is a GIGABYTE GA-K8N-SLI the ram is four sticks of 512mb Corsair VS512MB400 (PC 3200) I'm thinking that I may need to buy a new board or see if I can RMA it.
