In Linux Hell

My Red Hat server has not had X running on it for months. Whenever I would upgrade, it would be unable to start the X server, and would give indications of a hardware problem. I bought a new video card for it, with no joy.

I recently decided to upgrade to Fedora. It stopped as it was trying to load the X upgrades, with a fatal error, telling me that it was either bad media (the CD passed a media check), inadequate disk space (it’s an almost-empty eighty gig drive), or a hardware problem. I replaced the motherboard with a different kind, thinking that the problem might be in the AGP section. Same result.

The worst thing is that since it only did a partial install, I can’t boot it any more, except in rescue mode from the CD. All of my data is still there when I mount the partition, so I’m trying to figure out how to back it up and just do a clean install, in hopes that this will finally get me around whatever the problem is. Does anyone have any thoughts as to other options, or just what the issue might be?

[Update a few minutes later]

Is there some way to get it to bypass the X installation, so I can at least complete the Fedora upgrade, and then try to fix X separately? For instance, if I do an install instead of an upgrade, is there some way I could deselect those packages, but still preserve the data in /home?
