Hi guys. Yesterday, when my computer froze, I had to unplug the computer. Suddenly, when I turn on my computer, the pc hangs on the hp splash screen. I tried pressing f10 for setup, nothing happened. Insert a cd into the disc drive, nothing happened. Whenever I unplugged my Seagate Barracuda 7200.11 500 Gigabytes, it could pass the splash screen. But, when I plug the hard drive back in, I could hear the drive spinning normally. Originally I thought the hard drive was dead, but I'm not sure. I bought my pc back in 2008. Can anyone help me?
