Got up this morning turned on my machine and within a few minutes the video blew up locking the machine. The machine has been running rock solid and other than an MSDN DVD installation yesterday nothing new's been installed on this box for quite some time.

So, I troubleshoot, right? Reboot - and boom the box blue screens when it loads into Aero. Reboot again same thing. Reboot into safe mode and it comes up fine. Disable any unnecessary drivers, reboot and it still locks up (no more blue screens now it goes into Aero and after 2 or 3 seconds either blacks the screen and locks or brings back a completely scrambled screen and locks).

So, I try different drivers. In the course of Vista's release I've run about 10 different drivers all of which have worked with different kinds of quirks. None of them work now -different visual effects but same end result of a locked machine or a blue screen.

But here's what really sucks about troubleshooting this in Vista: I can boot up in Safe Mode and that works just fine, but nowhere in this fucking process can I choose to install the generic VGA driver permanently. Vista doesn't show the driver anywhere, doesn't allow selecting it nothing. So I can't at least try and boot up without nVidia drivers.

More importantly though, while in Safe Mode I can't turn off Aero for when the machine comes back up with the nVidia drivers. I suspect whatever the problem is has to do with the higher end features of the card, so running in non-Aero mode probably would at least let me continue to use the machine for a while. But I can't see a way to tell Vista NOT to use Aero when it comes back up.

I finally managed to boot up with a VGA driver by removing all the nVidia drivers one at a time in Device Manager:

  • Select the active nVidia Drive
  • Uninstall the device
  • Scan for changes
  • Uninstall the next driver

Repeat until there are no drivers left - then reboot. At this point I actually boot into the VGA driver, but upon boot Vista helpfully AUTOMATICALLY installs a new (supposedly the install default) nVidia drivers, so I can't seem to make the VGA driver permanent.

To Vista's credit it looks like this problem is a hardware issue not a Vista or driver issue as all the drivers are failing for me. I even plugged in my other hard disk that I used to run a previous version Vista with and it too fails with the same exact failure.

So now I'm looking at dealing with warranty with Dell. I know that'll be loads of fun since the machine was purchased with XP.

FWIW, this nVidia card has been the worst investment ever in a machine. The nVidia Vista drivers have been absolute crap and have never been really stable. To this day these drivers (when they were working) would cause funky behavior with dual monitors and odd 'black outs' where the screen occasionally would just go blank for a couple of seconds and then pop back as if the card was resetting itself. Until the most recent driver you couldn't even tweak teh basic video settings like color balance contrast etc. Pathetic - nVidia had only what 5 years to get ready for Vista and now they're issuing letters of apology... Now this apparently hardware failure after almost exactly one year of service is really the final straw.

I've never been one for buying high end video cards and the only reason I ended up buying the nVidia card because it was the only thing available that would run Aero...

<sigh> now the fun begins wrestling once again with Dell and support trying to get this defective card fixed/replaced. This is almost EXACTLY 1 year after I got the machine (shipped 1/26/2006) - how convenient. Luckily when I bought this machine I opted for the higher end support so hopefully this can be done in a somewhat timely manner.
