Einleitung
The Random Access Memory (RAM) module is one of the more common components of a computer to fail and need replacement. The RAM is used by the CPU to store information that it will need to retrieve quickly or often. Nothing is permanently stored on the RAM module so you will not lose any data after the replacement. RAM modules are "plug and play" components which means that they can be removed and replaced very easily. The tricky part is getting to them inside the computer. The replacement RAM module should be left in the package until it is ready to be installed as any foreign material that gets on or in the RAM module may affect the performance of the component If your computer is running slowly and commonly used apps and functions are showing error messages this guide will help you replace the RAM module and fix the issue.
