Such as this one. These errors piss you off the most.
Why? I don't know. It seems to be happening on the new ASUS P5AD2 Premium motherbords that I have with the new PCI-E 6800 Ultra's, with BIOS version 5.40.02.25.03, drivers 61.76's. I'm installing the 61.76's because the 61.77's kick out to a black screen after a WinPE install (I'm guessing because they are not signed... Though, I'm waiting on official word from Walt first...). It's a odd error, to be sure, and fortunately for me, it only happens every so often, like 1 out of 4 installs. But, to me that is frequent enough to be wary.
The error happens at the 34Min mark, and/or the 33Min mark. During which time, a correct install will have the screen "flicker" black about 3 or 4 times for about a half second and then continue on. I take it the Nvidia drivers are being installed/loaded or unloaded during this time and the install bluescreens because it reloads/unloads/reinstalls the framebuf.dll driver file. An incorrect install has the screen flicker than "BSOD!".
Since this problem happens sporadically, and ONLY when the Nvidia drivers are being loaded as well, I suspect that it is the loading/unloading of the drivers (if it does such a thing) or it is the Nvidia hardware.
