Insufficient Virtual Memory
You have huge probabilities of experiencing this problem if you have just installed an app that needs huge memory. Another reason for this is your low RAM space. Unless your RAM is enough, you will have to purchase additional RAM chips. Your pagefile size can however be increased if your RAM can still do the work. First, go to Control Panel, click System followed by Security. Click on Advanced system settings, point your mouse to the Advanced tab and click Settings. This time, you are able to adjust and increase your pagefile size from 1.5 up to two times your RAM’s memory.
