I just tried to install an new VisionTek HD4870 card on an ASUS P5Q Deluxe.
I previously had an eVGA 7900GTO card.
After I installed all the ATI drivers and rebooted, Windows Vista x64 starts booting, but then goes to a blank screen. I can boot the PC in safe mode, but I can't get it to work in normal mode with ATI 4800 driver installed. I can boot into normal mode - but only without HD4870 drivers installed (just plain VGA mode).
Has anyone had a problem like this before? I tried the latest hotfix driver without any success.
