Usually because the new guys have asked questions that have been asked and answered hundreds of times and they could have easily gotten that info by doing a little research. That, or they come in with some inflammatory remark like "AMD is far superior to Intel" and provide absolutely no facts to back their statement up.
The reason you got attitude from me was because of this:"Or are you all just a bunch of prima dona wannabes?". Don't come in to a forums as a new guy, insult us and then expect answers. It's just not going to happen. Also, you never stated in this post what was wrong with the mobo. How can you expect help without divulging info? Tell me what is wrong and I will either try to help myself or I will try to point you in the right direction.
