Start by reseating the RAM sticks, which involves taking them out of their slots and putting them back in firmly until they click into position. Frequently, this easyraja luck step fixes connection problems that might be preventing proper functionality. If reseating doesn't work, testing each module separately can help find hardware issues. You can find out if a particular stick is the issue or if there is a problem with one of the slots by taking out all but one module and trying to boot the system.
