Hey guys. I was doing a driver upgrade on my Dell Inpsiron 15 laptop running Windows 7 Ultimate RTM x64.
From version 126.96.36.1992 to 188.8.131.522.
My primary display was set to 1366x768. but I was currently using the Projector Only setting in Win 7, and hooked up to an external projector via VGA-out at 1280x800.
The driver install process halted after the point where the previous driver is unloaded (black screen with blinking caret), and the new one loaded in (screen is supposed to reappear as normal). Screen did not appear, the system actually locked up.
