A bad laptop memory module can wreak havoc on your machine. When this part is failing, or has failed entirely, your laptop could demonstrate a wide variety of signs that can help you diagnose the problem. Fortunately, replacing a bad memory module is a simple, step-by-step process. Using our guide can help you every step of the way.

Now, to tell if your memory module is the likely culprit behind laptop problems, look for these signs:

• The computer will not boot, but beeps constantly. Replacing the memory module will often cure the problem.
• Your computer blue screens, also known as the “blue screen of death.” If the error shown is IRQL_Less_or_Not_Equal, your memory needs to be changed.
• Frequent crashes occur when you are trying to use programs that are memory intensive. Video games, for example, might tax the system too much to play. Crashes that occur during normal operation can also be related to the memory module.
• The display is distorted and video card problems are not suspected.

If you want to test RAM before replacing it, there are diagnostic tools you can use. It is also possible to use a simple process of elimination test. Power down the laptop and remove the memory module. If you have another available slot for it on the motherboard, try it there. If the problem corrects itself, your slot is bad and not the memory.

Should you discover that the memory module is in fact bad, just purchase a proper replacement and follow our guide for installation. If you suspect a motherboard issue, you can also replace this part yourself.
