Dell laptop running Windows 7. Suddenly started having an issue with slow startup, freezing. If I wait long enough (maybe 40 minutes) eventually it will seem to be okay, but then will freeze. Also got a warning saying that the system needed to shut down to prevent damage. Ran a Dell diagnostic and got a code 2000-0142. Also got a code 0xc00000e9 when trying to run system repair. So apparently the HD is bad? I tried removing the HD from the laptop and attaching it via USB to another computer, and it seemed to work fine, was able to access files. Another weird thing is that the taskbar suddenly looks "old-fashioned", if that makes sense. Just looking for some direction here, is the laptop toast?
