my pc said "oh shit"

First it was the random shutting down, then it was the fried power supply, and now.. well.. my home PC just decided that it's had enough. I'm not sure what happened, or why it happened, but I'm going to assume the random popping noise and the processor fan popping off, as well as the fact that nothing connected to the motherboard powers up.. probably means the computer is dead. So, I broke down and ordered a new one, lets hope this one doesn't sound like an aircraft carrier at all times and is a bit more willing to live.
