I have a gigabyte GA-B75M-D3H motherboard and a pair of 2gb kingston hyperX genesis on dual channel on ddram 3 and ddram 4 slots. I bought a 4gb kingston hyperX fury ram stick to add to it but when I plug it on ddram2 slot I get short beeps with no pattern repetedly and if I put on ddram1 slot the computer keeps turning on and off with no error beeps and no post beeps. If I connect the new one alone my computer will start, if I connect the new one and a single 2gb one my computer will also start, but I can't find a way to put the 3 all together and have my computer running. I am asking because I have a few days to contact the seller and ask for my money back if that is the case so I would like to know if there is anything I can do for this configuration to work. I don't know if I should upgrade bios, get another one of the same type and have 2 pairs, each pair in dual channel, change the order on the slots, etc. Here are some images:
