Blue Screen of Death
Insufficient Virtual Memory
This error occurs after you have installed a big app. Besides that, this can also happen when you have inadequate RAM space. You can purchase additional RAM chips if it is insufficient. However, increasing your pagefile size will do if you think you could still work on your RAM. Enter Control Panel, click System and also find Security. Click on Advanced system settings, point your mouse to the Advanced tab and click Settings. This time, you can then adjust and increase your pagefile size from 1.5 up to two times your RAMs memory.
