What is the symptom of a hard drive that's crashed? My wife's Dell laptop started acting slow and noisy, like gears were driving inside. Then, upon turning it on it would show the Dell logo and the loading bar. After that the screen goes black with a cursor in the upper left hand side for about a minute. Finally, it comes up with two loud beeps and says that it failed to boot the C drive (I believe). Is it dead? To add,It does allow me to get to set up however. We end up having to manually turn it off.
