You must take out all of the old ram as the max out for this system is 2 2GB memory cards. Put one in the slot closest to the cpu, then skip one and put the other. Since there are 4 slots 2 should be of one color and 2 another color. Boot the system up and it should work. If not then you didn't check the specs and got the wrong memory sticks.
THANKS! i wasn't quite sure how the slots were divided ( i knew they were split into 2 groups of 2, but wasnt sure which was which, so i hadnt tried that. ill go check that now!
EDIT: ok, after trying that, i still cant figure out if its worked, because now there is no signal for the video :/ what could i do to fix this NEW problem?
