Windows Virtual Memory

I have a question for you all. Why does my laptop computer shows this message?

Windows Virtual Memory Minimum Too Low. Your system is low on virtual memory. Windows is increasing the size of your virtual memory paging file. During this process, memory requests for some applications may be denied. For more information, see Help.

Please tell me why this happens and what should I do to solve this problem. I am using Microsoft Windows Service Pack 2 Home.

Happy Fish Fry Day!

Wish you all a very happy fish fry day. Hey, what am I saying? Fish Fry? How can I fry this fish? I mean just look at it. It looks so nice. Today is Friday, but I did not had any fish. I ate soyabean with rice and Dal. This fish belongs to our neighbour. They kept their fish for a week with us. They were out of city to celebrate the new year. We changed the water every two days. What is the name of this fish? Any guess?
