If your computer memory is not recognised by your system, it is necessary to troubleshoot the cause of the problem. The first step in troubleshooting computer memory installations is to reseat your memory modules on your motherboard. Reseating memory modules often works to correct problems with your computer's RAM, according to Microsoft. Computer memory can be unseated over time during the general maintenance, cleaning or moving of your computer. Save time with your troubleshooting process by reseating your memory modules yourself.
Shut down your computer and disconnect your computer's power cord and any cables connected to devices such as monitors, keyboards or other peripheral devices. Press the power button on your computer to remove any remaining electrical charge from internal components. Turn your computer's power supply switch to the "Off" position.
Remove the screws that hold the side panel of your computer case secure. Pull the side panel off of your computer case and set it aside, out of your workspace. Touch the metal frame of your computer case or the metal housing of your computer's power supply to ground yourself and prevent the discharge of static electricity.
Flip the securing clip on either end of your computer's memory slot out to unlock the memory module. Grip the memory module on both sides and pull up. Gently rock the module back and forth to unseat it if the memory module doesn't slide out.
Line the memory module with the motherboard's memory slot and press it back into place. Press down on the memory module until the module clicks into place. Flip the securing clips on either end of the memory slot up to lock the module into place.
Replace the side panel on your computer and tighten the screws to secure it. Turn your computer's power supply switch to the "On" position and connect your power cord and computer peripherals. Reboot your computer.
Do not move your computer quickly or roughly when connecting its power cable or peripherals. Doing so may unseat your memory modules and force you to reseat them again.
