Changing the memory in any desktop computer is a relatively simple task. Follow these steps to make it quick and easy upgrade of the memory in your computer.
You'll need memory modules. Depending upon your upgrade, you may be adding to existing memory already installed, or you may be completely removing existing memory and doing a full replacement.
The first and most important step is to close Windows and power down your computer. Doing this will keep you and your computer safe during this upgrade.
If you have a Dimension 2400 or similar computer, then your computer will open this way. Just pull down the latch and then slide the left side panel of the computer toward the back and it comes off.
Most folks with OptiPlex machines will find that their computer case opens this way
This is also an excellent opportunity to help your desktop computer run cooler by evicting dust bunnies from the inside of your computer. Yuck! You can use canned air or just a vacuum cleaner.
To remove existing memory modules, push down on the locking tabs located at each end of the memory. Then lift the memory up and out of the way.
Make sure you have the slot(s) in the memory lined up with the notches in the slot in the PC and apply firm pressure to seat the memory into the slot until the locking tabs snap into locked position.
This video shows a close-up of one end of the memory slots. Note that each memory module slides into a notch at each end. You can better see how the locking tabs work to hold the memory in place.
Now put your computer case back together. Once it is closed up, check all of your computer's connections to make sure that none worked themselves loose during this process.
When you power up your computer you should see a message letting you know that the amount of memory has changed. Press F1 on the keyboard to continue..
CONGRATULATIONS! You just successfully upgraded the memory in your desktop computer
