My computer (specs in sig + latest version of snow leopard) started running sluggishly, and just today froze constantly. I decided it was time for a reboot. Because i was unable to boot from my HD normally (constant freezing) I had to boot it in safe mode. From there I was able to backup all my files (luckily) and proceeded to insert the mac osx install DVD. I was able to get through 1/5 of the installation when it suddenly stops and gives me an error "cannot find suitable support files" or something along those lines. I then go to disk utility to check the permissions, or too see if something else is wrong, but the HD doesn't show up at all. Next I go to the 'startup' utility only to find that my HD isn't even on the list anymore.. Un-bootable. Is there anyway to get the HD to show up again, or is it completely *#%^+ ?
