Graphics Issues / Glitches

ElvenshaeElvenshae Registered User regular
So, this started about two weeks ago while playing Fallout: NV.

There was a particular NPC (the Sunset Sasparilla guy) where, every time he would come up to talk to me at a particular Powder Ganger camp, I would get these weird graphical glitches. Partway through the conversation, parts of the screen would become dotted with pixels of random colors. Within about 30s after that, they'd develop into lines, and then everything would crash. This did not happen when I ran away from the camp and let him meet me somewhere else, so I figured it was one of those lovely F:NV bugs.

I later read about F:NV having some issues with nVidia cards, so I updated my drivers with the most recently available full release from nVidia.

Then, this morning, the same thing started happening in World of Warcraft - random pixelation turning into horizontal lines with a crash.

I rebooted my computer, and the same effect started happening on just the Windows desktop - though in this case, the pixels were closer together (clustered at the top of the bottom bar).

So, I rebooted into safe mode w/ networking, downloaded and installed Avast (I usually run Norton, for what good that does me), and let it do a virus check, which came up clear. While the virus check was running, the horizontal lines largely covered the entire screen.

So, I come to you knowledgeable types. What troubleshooting steps should I be taking next? My gut feeling is that I might be looking at a dying video card, which would absolutely suck right now. Seriously, it could not be worse-timed.

Running Vista x64, 2x 8800s of some stripe in SLI mode.

    Update: So, I took the cards both out, blew them down with some compressed air, cleaned out the case a bit (I'd done this just a couple a little while ago when I replaced my CPU, so it was pretty darn clean), and put the cards back in in reverse order (the bottom card on top, the top card on bottom).

    Windows (via Device Manager) is now reporting that one of the cards is not using any resources because it has an error. Unfotunately, right-clicking on it does not give you a "Troubleshoot" option or a "List Errors" option, so I'm still digging.

    They're 8800 GTs, BTW.

    And now I can't get Avast to shut up and go away.

    Sounds like they are going bad, not a virus or anything. Try using each card separately, to see if you can see which one exactly is failing.

    Yeah, that's kind of my fear.

    Okay, so it turns out the error is "This device is stopped because Windows cannot load device driver."

    So, I went back to nVidia, downloaded their most recent driver, had it do a clean install.

    When my computer starts up, I can see the BIOS splash screen, then Windows loads.

    The nVidia control panel tells me that I have an SLI capable system. Turning SLI on causes the nVidia control panel to crash, which does not save the SLI congifuration information. Upon restarting, Windows had to boot into Safe mode.

    I uninstalled both cards' drivers, and loaded them up with the defaul VGA adapter, and then made a (what I hope is) a "no, seriously" clean install of the drivers. It now recognizes both cards as 8800 GTs.

    I'll now try restarting into normal Windows mode to see what happens.

    Yep, sounds like one is dead. Which ever card is your current secondary, put it in the primary slot, and don't put the other card back into the system. If it still has glitches and errors, then that card is dead.

    Go into settings, disable sounds.

    ...and I thought of how all those people died, and what a good death that is. That nobody can blame you for it, because everyone else died along with you, and it is the fault of none, save those who did the killing.

    Hah! No, I meant more like, I downloaded Avast as a second check for viruses, just in case my primary AV program missed something. Avast didn't find anything, so I wanted to turn it off and uninstall it (since running multiple AV programs still isn't, as far as I know, recommended).

    I couldn't find a "Shut down" option in the Avast control panel, I couldn't end the associated processes, and I couldn't uninstall it because it was running. I ended up uninstalling it while my computer was in Safe mode. :D

    Turning off SLI results in a stable system - so far, at least. More testing is required to ensure which card is going bad - because it's not entirely bad yet, and will run for hours sometimes before borking, but I think I've got my answer. Thanks for the help!

    Now to research video card upgrades. To the Build Thread!
