This is not particularly an ubuntu problem (it is related to hardware in general), but I have found this a helpful community, so I am going to seek advice here.
My church's laptop (XP Professional) which we use to store sermons and project song lyrics onto our screen, has recently taken a turn for the worst. The computer is getting a PXE error on start up. I have found various articles about this on the internet (see bottom of post) and they all seem to point to one thing. A hard drive problem. It is possible that the hard drive is just busted, but I have a lot of people depending on me, and I would like to restore it if at all possible. My hopeful thoughts are that it is simply a bad hard drive connection that I can remedy by snapping or plugging something back in. This is probably not the case, but if it is, I would like some experienced advice for checking that the hard drive is connected properly and fixing the connection if need be.
The computer makes crazy buzzing noises when I turn it upside down while it is running, and it makes unusual noises when attempting to boot as well.
EDIT--By the way, I am able to boot from a CD. I have booted it up with my 8.04 live CD, and gparted does not detect the hard drive, so that leads me to believe that is the cause for the problem.
EDIT2--Actually, now, after the live CD was irresponsive and I had to force shut down. The computer boot message is
"A disk read error ocurred
Press Ctrl+Alt+Del to Restart"
It now even refuses to boot from a CD.
