I'm not sure what's wrong with my old desktop. All I did was shut it down like normal, after it shutdown, I then quickly unplugged my slave hard drive, but a few minutes later, I came back into the room and noticed that the power supply fan came back on. Not only that, but my computer's hard drive indicator LED and power LED was blinking. I unplugged everything and reinserted the power cable, but it still does it. I also smelled burnt plastic. Anyone have an idea of what's going on? Is it just dying because it's 4 years old and pretty crappy? I have an idea of what component is at fault, but please let me know what you think. Thanks in Advance.
