How to Restore Computer Memoryby Martin Woodfield
If your computer experiences sudden slow downs with an inability to handle the processes of certain programs, you may have faulty memory (also known as RAM). Before replacing the RAM check your user manual and computer specifications to determine the type and size of the faulty RAM module currently in the computer. If you are interested in upgrading the amount of RAM as well, also check on the RAM capacity.
Shut down the computer, then remove the power cord and all connected devices. If your computer is a laptop, also remove the battery.
Remove the side panel of the computer to expose the inside. For a laptop, flip the computer over, find the RAM door near the battery port and remove it.
Locate the RAM module slots connected to the system board.
Lift the latches on the ends of the slot to release the current RAM module.
Slide the current RAM module out of the slot and set it aside.
Align the new module with the RAM slot and gently press down on it. The latches will lock down when it is in place. Replace the side panel or RAM door and reconnect the power cord and battery, as appropriate, to finish the process of restoring your computer's memory.
