Installing additional physical memory significantly boosts the performance of laptop and desktop computers. Adding more memory causes applications to run faster and operating systems to boot quicker. Upgrading physical memory is not difficult and can be completed in only a few minutes. Follow these steps to safely upgrade the amount of memory in your PC, Mac or laptop computer system.

Things You'll Need

• Computer owner's manual

Instructions

1. Consult your computer or laptop owner's manual to determine the maximum amount of memory your particular system can take. The manual will also tell you what type and speed of memory you need to buy (512MB of PC2100 DDR-266 for example). Purchase the new memory online or through a local computer retailer.

2. Turn off the computer, unplug it from the electrical outlet, open the case, then touch something metal to eliminate static charge. If necessary, refer to your owner's manual to learn how to open your particular computer case, MacBook or laptop memory cover.

3. Locate the memory slots on your motherboard. If you don't have a free slot, remove one or more of the existing memory modules by pressing down on the plastic end clips that hold the memory in place, then gently pull the module out of the slot. In a laptop, release the metal clips on each end, then remove the module at a 45-degree angle.

4. 

   Line up the notches of the new memory card with an open memory slot on the motherboard, then snap it into place by pressing down on one end and then the other. Close the latches or clips on each end. Insert laptop memory at a 45-degree angle, then press the module down flat until the clamps lock it into place.

5. Close the case or replace the memory cover, then plug the computer or laptop in and turn it on. If it starts to beep, the memory is not installed correctly. If this is the case, repeat Step 4 to ensure the memory module is aligned properly and securely snapped into the memory slot.

Tips & Warnings

• When handling computer memory, avoid touching the gold or silver contacts, which can damage the module. Make sure the module notches are lined up properly with the motherboard when installing memory cards or you will damage the circuitry.
