I had 4 GB of RAM and i just bought another 4GB stick of RAM. I had 1 more empty slot open so i ended up putting the new one in there. I launched up my PC and it still says 4GB RAM installed, i have Windows 8.1 and i heard when u install a new RAM it updates immediately. I also tried putting the New RAM in the slot my other RAM was in and it was reading it also. I dont know what to do anymore.. Please help.
