1. Computer has no display and you get a beep code. In some motherboards it is a long beep sound.
2. Computer always restart that might cause BSOD, General Protection Fault error messages, Illegal Operations, Fatal Exceptions, etc.
3. Computer fails during O.S. installation or other program installation fails.
If one of the above are the one you experience on your computer, that is the time you need to test your computer memory. If you have 2 or more memory installed on your computer, test it one by one so then take note the results for each memory.
