I tried uninstalling then reinstalling the drivers downloaded from Dell's site. Installed properly, no issues, rebooting in safe mode, new hardware recognized. Reboot normally, back to BSOD. I tried installing updated drivers downloaded from NVidia's site - same result. I tried System Restore three different times, going back to three different restore points upt to a week before the error began - reboot normally = same BSOD.
Note: I'm not a gamer, not running any programs with extensive graphics requirements. Mostly industry standard apps (Microsoft Office 2003, Quicken, Adobe Standard) -- also use Macromedia Authorware 7.02. ZoneAlarm Pro firewall. avast antivirus. AdAware SE, Spybot 1.4 all kept updated - ran McAfee's stinger.exe to double check and make sure a virus hadn't slipped through - nothing.
I can boot to Safe Mode. Don't know what else to try. Should I remove the video card and reseat it?
