About three days ago, i went on my computer and it wouldn't boot up, several hours before it was working perfectly. So I turn on everything and both the Power LED and Loading LED (red light that indicates the computer loading something) are both on, and my F: drive light is blinking. My Hard drive does not spin either. Usually i hear a beep noise, but it doesn't and just hangs there, with a blank screen. I searched on the internet and mostly says to try and unplug some of the memory/components and turn it back on. It doesn;t do much. But when i unplug my hard drive, not from the motherboard, but from the hard drive, it starts to spin, But it still doesn't turn on. So whats going on?
