Insufficient Virtual Memory
If you have recently installed an application that needs a huge memory, you are most likely to experience this problem. Other than that, this can also occur when you have inadequate RAM space. In case you have insufficient RAM space, you will need to acquire more RAM chips. Your pagefile size can however be increased if your RAM can still do the work. Enter Control Panel, click System and find Security. Click on Advanced system settings, point your computer 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.
