Low Virtual Memory
In case you have recently installed an app that needs a huge memory, you’re probably to experience this problem. Aside from that, this can also happen when you have inadequate RAM space. Unless your RAM is enough, you will have to buy more RAM chips. On the other hand, increasing your pagefile size will do if you believe you could still work on your RAM. First, just go to Control Panel, click System followed by Security. Follow the order of the areas you should be going: Advanced system settings, Advanced tab and Settings. You can then increase your PageFile up to two times of your RAMs memory.
