Of all the components in your computer, random access memory can be one of the most uncertain. If you have a laptop equipped with an optical DVD drive, you can bet that this will be the first piece of hardware that will fail, but this is something that is easy to deal with. A hard drive failure can be catastrophic if you do not have a data backup strategy, but at least you get warnings most of the time. Bad RAM is more of a headache because it directly interferes with the overall performance of your device.
Why Does RAM Fail
RAM is not supposed to last forever; in most cases, it will last longer than a hard drive but not as long as the processor or power supply. In general, you can count on RAM functioning perfectly while your system is still under manufacturer’s warranty, and it may not give you any headaches for a few more years. The problem with defective RAM is that it can be a bit difficult to detect.
Symptoms Of RAM Failure
When your PC freezes or unexpectedly shuts down, bad RAM may be at play if it performs optimally upon rebooting the system but gets sluggish later. A strong sign of RAM failure would be corrupted files that were recently created or edited.
There are various ways of diagnosing RAM chips; one of the easiest methods is to remove some of them and test the performance of the machine. Windows has a built-in tool to conduct memory diagnostics that tells you if errors are detected, but this requires physical confirmation by means of testing the individual chips. A better method is to run benchmark tests and use special diagnostic tools.
