If your computer is running low on RAm, there are several steps you can take to fix the issue;
1 - Close unnecessary programs: If you have multiple programs open up at once, close the ones you're not actively using to free up memory.
2 - Check for memory leaks: memory leaks occur when a program doesn't release the memory it's using, even after you close it. you can use the Task Manager (Windows) or Activity Monitor (Mac) to check for memory leaks and close any affected programs.
3 - Increase Virtual: Virtual Memory is a feature that allows your computer to use hard drive space as if it were RAM. You can increase your virtual memory by going to your computer's settings and adjusting the page file size.
4 - Add More RAM: If none of the above solutions work, adding more physical RAM to your computer can increase its memory capacity. Check your computer's specifications to determine how much RAM it can handle and purchase the appropriate amount.
It is important to note that adding more RAM required opening up your computer and may void your warranty, so proceed with caution.
