How to Reseat a Desktop Memory Module

These steps show how to reseat any kind of desktop memory. There are many kinds of memory a PC might use, but the reseating process is identical for all of them.

Power Off the PC and Open the Computer Case

Memory modules plug directly into the motherboard, so they're always located inside the computer case. Before you can reseat memory, you must power down the computer and open the case so you can access the modules.

Most computers come in either tower-sized models or desktop-sized models. Tower cases usually have screws that secure removable panels on either side of the case, but will sometimes feature release buttons instead of screws. Desktop cases usually feature easy release buttons that allow you to open the case, but some will feature screws similar to tower cases.

Now it's time to open your computer's case. For screwless cases, look for buttons or levers on the sides or rear of the computer that are used to release the case. If you're still having difficulties, reference your computer or case manual to determine how to open the case.

Remove Power Cables and Attachments

Before you can remove memory from your computer, you should unplug any power cables, just to be safe. You should also remove any cables and other external attachments that might get in your way.

This is usually a good step to complete before opening the case, but if you haven't done so yet, now is the time.

Locate Memory Modules

Look around inside your computer for the installed RAM. Memory will always be installed in slots on the motherboard.

Most memory on the market looks like the module pictured here. Some newer, high-speed memory produces more heat, so the memory chips are covered by a metallic heat sink.

The motherboard RAM slots are usually black, but I've seen yellow and blue slots as well.

Regardless, the setup looks essentially like the picture above in nearly every PC in the world.

Disengage Memory Retaining Clips

Push down on both memory retaining clips at the same time, located on either side of the memory module, as shown above.

The memory retaining clips are usually white and should be in the vertical position, holding the RAM in place in the motherboard slot. You can see a closer view of these clips in the next step.

Verify Memory Has Properly Disengaged

As you disengaged the memory retaining clips in the last step, the memory should have popped out of the motherboard slot.

The clip should no longer be touching the RAM and the memory module should have lifted out of the motherboard slot, exposing the gold or silver contacts, as you can see above.

If the memory module came completely out of the motherboard slot, then you simply pushed the retaining clips too hard. Unless the memory slammed into something, it's probably okay. Just try to be a bit more gentle next time.

Remove Memory From the Motherboard

Carefully remove the memory from the motherboard and place it somewhere safe and static free. Take care not to touch the metal contacts on the bottom of the RAM module.

As you remove the memory, take note of the one or more small notches on the bottom. These notches are asymmetrically placed on the module (and on your motherboard) to help ensure that you install the memory properly (we'll do this in the next step).

Reinstall Memory in the Motherboard

Carefully pick up the RAM module, again avoiding the metal contacts on the bottom, and slide it into the same motherboard slot you removed it from in the previous step.

Push firmly on the memory module, applying equal pressure to either side of the RAM. The retaining clips should pop back into place automatically. You should hear a distinctive 'click' as the retaining clips snap into place and the memory is properly reinstalled.

Verify Memory Retaining Clips Are Reengaged

Take a close look at the memory retaining clips on both sides of the memory module and make sure they're fully engaged.

The retaining clips should look just like they did before you removed the RAM. They should both be in the vertical position and the small plastic protrusions should be fully inserted in the notches on both sides of the RAM, as shown above.

If the retaining clips aren't fitted properly and/or the RAM won't set in the motherboard slot properly, you've installed the RAM the wrong way or there may be some kind of physical damage to the memory module or motherboard.

Close the Computer Case

Now that you've reseated the memory, you'll need to close your case and hook your computer back up.

As you read during Step 1, most computers come in either tower-sized models or desktop-sized models, which means there might be different procedures for opening and closing the case.
