Also, you might see the error for the first time if you extend or decrease the RAM capacity from your PC and instantly turning it on. For this, I would prefer changing back everything you have done to the computer to save the data as well as the backup. Let it be any new driver installed or any new software installed, just uninstall them as soon as possible to not get the same type of error again.
