Well, let me say it clearly. I do not know anything about computers and the only reason I am here is because my system is malfunctioning. Please help me. It says that I have a device error when i switch on the windows. Earlier my elder brother used to do something, but now he is abroad and he cannot help me. It was a friend of mine who told me to get help from this site, and I am new to this forum thing. Please help me. Also what are these BBCode and Signature? What is this poll thing also? Please tell me as i am totally new to these things and all.
