When your computer crashes, the appearance of a blue screen means something is wrong with your hardware. Also known as the "Blue Screen of Death," its appearance can signify that you have a problem with your memory. Even if one stick of RAM memory is faulty, it can affect how your computer performs. Although a blue screen can be caused by many different occurrences, checking your memory is important for ruling out faulty RAM.
Click on the "Start" button and open the "Control Panel."
Type in "memory" in the Control Panel's search bar located at the upper right hand corner.
Look for "Administrative Tools." Click on "Diagnose your computer's memory problems."
Choose "Restart now and check for problems" to run the scan immediately. Wait for the computer to restart and then follow the instructions. When the scan finishes, the diagnostic tool will let you know if RAM is the cause of the blue screen error.
