FC8 trouble

[andycon]

Hello,

I'm about at the end of my rope at this point. Let me try to explain my situation briefly.

I purchased an XFX GeForce7900 video card a while back. It was working well, until it started overheating randomly. After it happened a few times, I ended up with some sort of corrupted log file which couldn't be overwritten for some reason, so my x server wouldn't load (as it needed to overwrite the old log file in order to create a new one and load the x server I guess?). At that point I was frustrated and I had been waiting to upgrade from FC7 to FC8, so I popped in my FC8 live CD, formatted the harddrive, and installed FC8. Now I'm having all sorts of video issues.

FC8 seems to have installed with the "nv" driver being loaded by xorg.conf. This just won't work for me for some reason (I'm using the onboard GeForce6150). Once the graphical part of the boot process starts (past GRUB, GRUB seems to work just fine), my monitor goes black and I can't see anything that's going on. I've tried to Ctrl+Alt+F1 to get to a command prompt, but the screen goes all corrupted on me and displays random blocks of green and white on the black screen. I've tried hitting "I" during the earlier part of the boot process to stop it from trying to load the x server in interactive mode, but before interactive mode starts, the screen goes black again, and nothing happens. If I could only figure out some way to get FC8 to install from the live CD with vesa as the driver, I could probably take it from there. I've also tried using my roommate's computer to burn the full installation DVD but it keeps crapping out on me, so that's not an option.

PLEASE, I'm going nuts here. Does anyone know a way to influence which driver is written to xorg.conf during installation of FC8 with a live CD? Or any other solution to my problem?
