I had been using DNA Drivers for my X800 XL, but decided to go back to ATI's official Catalyst drivers. I unistalled the DNA drivers through the remove programs panel and it asked to restart, which i let it do. POST goes fine, Windows XP loading screen comes up, but at the point where I should get the log on screen, all there is is a blank screen.

Windows is still there...I type in my password and hear the log-on sound, but still no video. One time it managed to boot into Safe mode. I tried installing the Catalyst drivers, but halfway through installation it told me I was missing a video driver. I restarted and now I can't even access safe mode. I tried rolling back to the original BIOS that came with my motherboard (Asus A8n-SLI Deluxe) which I know is stable. No luck there. For some reason it seems windows can't control the video card, even though the card works fine up until the log in screen. I tried putting in an old PCI card which I know works fine but still get the same problems. Windows is there...I can log on...but no video. Is there any way to get video back without reinstalling windows? I'd prefer not to lose all my data.

After doing a repair install of Windows, I am now able to access safe mode (with video). However, normal boot still lacks video. I tried running Driver Cleaner to get rid of all video drivers, but after doing that and rebooting into safe mode, I can not install any video drivers. I get a message saying to install DirectX and then another error reading - something about an INF error. I try to install DirectX but it tells me it is already there. It seems like the best I can do is to burn all my data to discs and do a fresh install of windows (which would be a royal pain considering how many programs I would have to reinstall), but I'm worried as to whether this is merely a Windows issue solvable by a fresh install or if this is a system/motherboard/videocard/BIOS issue, in which case doing a fresh install wouldn't fix anything and I'd be stuck with a rather expensive pile of junk. Any ideas before I wipe the drives (I have two 80gigs running in RAID0, using the RAID controller that is part of the Nforce4 chipset, if that helps)?
