I have a Lenovo Z570 with 2 4gb DDR3 RAMs. But for some reason the laptop which used to say I had 8GB of Installed memory now says there is only 4. Recently I had opened the panel to the RAM slots to put back a dislodged RAM chip and almost immediately after that this issue started. Any solutions?



By the way I have 64 bit Windows 7. So that 32-bit problem is out of the question I Guess.
