Vista won't run graphics card
I'm having a problem with my PC, where Vista will no longer run my GeForce 8800 GT. It says it's disabled because of a "problem."
This started happening when I restarted after a Windows Update, and the display went all wonky. It's low-res, which I think means it's reverting to my motherboard adapter. Things were a bit wonky otherwise (freezing, my Rogers Online Protection program not launching), so I reverted to a restore point before the update.
However, things are still not working. I'm not freezing anymore, but my Online Protection doesn't launch correctly (but it does eventually), and my graphics card isn't working.
I'm also getting the kind of artifact you see in the attached image showing at startup, both here, at my Vista load screen, and at the BIOS screen.
What gives?
Worst-case scenario is that my graphics card is fried, but it seems unlikely because I haven't been giving it any heavy use lately (not much in gaming) and the problem started with a Windows Update.
I've updated my graphics driver, I've done a virus/spyware scan, etc. I'm not all that keen on hardware problems.
Can anyone help me out? What should I be doing to try to get Windows to switch to the graphics card? If it can't or won't, does that mean the card is screwed? Is it just a coincidence, or can OS updates mess up graphics cards like this?
WTF?
