Don't you just love error 43? So helpful and informative. "Windows has not started this device because it reported an error". Gee, thanks. I had this a couple of weeks ago on my laptop's Nvidia 8600M, but the screen still works at default resolution using the standard Win 7 VGA driver (VGAPNP.SYS). The laptop, of course, was just a few months out of warranty. :(( It would probably cost more to repair (BGA mounting) than to replace the laptop, so I shall struggle on for a bit as it is - everything works fine at 1440 by 900 - I just don't have the eye candy, and I can't play videos - no hardware acceleration. I have connected the second screen via USB. I.m just glad that VS2008 doesn't need H/W acceleration. :sigh:
