I just bought a refurbished X800 Pro on ebay for my brother. The listing said it was in perfect working condition. I got it in the mail last night and wanted to test it out. I uninstalled my card, rebooted into Safe Mode, used Driver Cleaner, then rebooted and installed Cat 5.11. After the install reboot, Windows XP seems to load up fine. But, before I get to the desktop, the screen goes black. The only thing I could do is restart the computer. So, I rebooted into safe mode again and tried the whole process of uninstalling/reinstalling again to no avail. However, I did notice one thing, in device manager it says it is a X800 XT PE! I'm guessing someone tried a BIOS flash on the X800 Pro... Is there anyway to get it working?
