did u changed them and tried ,if yes and still no use,did u checked u r specs to see max supported ram ?
I found the time to compare the memory modules that came with my comp. to the modules that one of them memory picker programs said what was in it. well not even close. my own fault for being lazy and not checking in the first place. needless to say they are on there way back to calif. as I am typing this. when new ones make it here ill keep you posted on the results. sorry for the delay
