Hello,

I myself build and work on computers, fix problems and other things but I thought maybe I needed another opinion. My problem is that two of my Dimm slots will not work. I have 4gigs and only 2 can be recognized. I know all my ram stick work because I have tested them out.As soon as I put a ram sticks in one of the other 2 slots that wont work it makes my screen stay black and nothing will show when I try to boot. Anyone one know if I can fix this? I just believe it's my motherboard.

The slots won't be fixable. You would need to replace the board.

Welcome to Geeks to Go.

You really answered your own question. The slots are bad and the only fix is replace the board.

There is a off chance that the slots are dirty/ contaminated, but that is slim.

Some Gigabyte boards (and maybe others I presume) can only use 2 sticks of RAM at one time even if their are 4 slots depending on the speed of the RAM. For example, 1066mhz in this board can only utilize two of the four slots and they have to use the two different colored slots. Gigabyte GA-MA785GM-US2H

Quoted from the memory support list.

Note: Due to AMD AM3/ AM2+ CPU limitation, DDR2 1066 or above speed is only supported by 1 dimm per channel.

What is the make and model of the board?
