Comp turns on, but shows nothing.

My mom's comp died a few days ago, but before it did, it said that "system32/drivers/ntfs.sys" had become corrupt. I'm trying to start it up with a disc to repair that file, but I'm getting no visual (I'm assuming it's just not producing any information for the monitor to display). I guess what I'm trying to get at is, that she has at least 10 gigs of irreplaceable files on the hard drive. What could I do to get them onto another computer? I have an external HD with plenty of room, but with the monitor showing nothing, I can't move the files. Can anybody help? She's really upset about it.
