Memory installation troubleshooting tips
Diagnosing the Problem
If the above programs indicate your memory sticks are functioning, but you still suspect a RAM problem or if you need to find which memory module is the problem, you can try removing the modules and placing them in different slots. Installed RAM
Fixing the Problem
Press harder when inserting modules into the memory slot.
Make sure the notches in your module are lined up with the keys in the slot, then press down using 20 to 30 pounds of pressure. While this may seem like a lot of force to use on a small module, it's necessary to properly "seat" the module. If installed properly, the clips on the side of module should snap into place on their own and a thin portion of the gold pins — 1/16th of an inch or less — should be visible (about the width of a line of pencil drawn on a piece of paper).
OS memory limitationsThe problem may not be due to your hardware. It could be your operating system, because there's a maximum amount of memory that a Windows-based operating system (OS) can accept.
Double-check your power cords
Make sure all your power cords are plugged in. We get multiple calls about memory not working when the computer just needs to be plugged in!
Double-check internal cables
Did you accidentally bump one of the wires or cables inside your computer while you were installing your modules? A loose hard drive cable can prevent your computer from booting up properly. Make sure all cables are firmly lodged in their sockets.
Update your BIOS
If your computer is older, it may need a BIOS (Basic Input Output System) update in order to work with today's technology. Don't worry — updating your BIOS isn't as difficult as it sounds. To update your BIOS, contact your system or motherboard manufacturer and they'll direct you to where you can download the software for free.
Test each of your memory modules one at a time
When you find the sticks that are bad you can order replacements. It is possible all the memory modules are damaged if your computer experienced a serious power surge.
If all the memory modules appear bad, then the problem is likely with the memory slot itself.
Try testing each memory module in each of the memory slots to find if one of the slots is faulty. To fix a faulty slot you would need to replace your motherboard.
Make sure the indention on the bottom is lined up correctly with the slot
Excessive heat in your machine can cause a variety of problems.
Failing Power Supply
Random reboots can be cause by a failing power supply.
Dirt and Dust
Dirt and dust can also cause issues that look like memory problems. It is a good idea to clean dust out of your computer at least once a year, more often if you have furry pets.
