Was operating 2 8800GT in SLI mode. Experienced a system hang while gaming after updating drivers and unable to do anything except a hard reboot. Noticed the well-reported graphic artifacts at the BIOS screen afterwards. Windows disabled 1 card with Code 43 and indicated the other was working properly. In trying to trouble shoot the video problem, the system chain BSODs with the "good" card installed by itself, but the one indicating Code 43 has been running by itself for over an hour with no problems. Still have graphics artifacts during BIOS splash.
Any ideas why the Code 43 card is more stable than the one Windows says is operating properly?
