This is the recommendation by NeedKarma 'THE EXPERT', I tried to solve the problem which was really consuming me becoming disastrous. The Problem was WINDOWS AUTOMATICALLY SHUTS DOWN.
The Recommended website given by NEEDKARMA:-
http://www.microsoft.com/security/incident/blast.mspx
It is clearly stated on this site that I should stop the process using CTRL ALT + DELETE.. The item which was needed to be stopped is 'msblast.exe'. But there was no such file like that. But I stopped the process of 'msstub.exe', which caused the computer to be saved from that kind of message box AUTOMATICALLY SHUTS DOWN. But it happened again even though I used all the three steps described on that link above...
Thanks for your attention...
