It's a computer that was built by my cousin and given to me as a loaner. Now you're telling me to start with the power supply but I mentioned twice that the power supply cooling fans are spinning but even though they are you're telling me that it still can be defective? I've had a power supply go out on me in one of my other computers but it was a simple visual solution because it burnt up. But this is nowhere near a concurring problem unless the problem is internal because the cooling fans on it still work. So to answer your question about the power supply, no I don't have anymore laying around.
