What are the signs of low memory?
Signs of low memory include poor performance, low-memory or out-of-memory notifications, and display problems. For example, if you try to open a menu in a program when your computer is low on memory, the program might respond slowly or appear to stop responding. If the menu appears, it might not respond when you try to click an item or it might not display all items. If you click a menu item, the menu might also disappear and leave a blank area on the screen instead of displaying the contents of the document or file you're working in.
