Drivers
 

Alright, so i just installed a new nvidea card, and when i did, windows did some automatic download of drivers. Due to my steam problem, however, steam reccomended downloading new drivers. So i went to the Nvidia website and used their auto-download service, being 99% sure that it would tell me if the driver was already installed. After installing it, however, mozilla firefox popped up with this text when i tried to run it:

nvidia display driver files from different (incompatible) versions of the driver have been detected. NVIDIA OpenGL acceleration is disabled to maintain system stability. to resolve this problem, update the NVIDIA display driver. The latest driver is available at http://www.nvidia.com

So i have a few questions.

1. What's the problem?
2. Did i need to uninstall any old drivers?
3. How can i resolve this?

...Sorry for being such a technoob x.x

uninstalling old drivers isn't necessary but it is possible to get the wrong drivers by mistake. usually the drivers windows installs are fine.

what card is it?

Nvidia GeForce 9400GT.

So i might've installed the same driver twice? How can i fix that? x.x

dun think it was the wrong one, though, cos nvidia pointed out the correct card and all that.

it wouldn't install twice, it would just install over the old one but it should be fine. you can try going to device manager and uninstalling the driver. it should find it and reinstall it itself after you do. if it doesn't just run windows update again.

oh yea, what operating system do you have? that's what happened when i got the wrong drivers. for some reason the url was messed up and it gave me the wrong one.

Windows 7. But that really doesnt explain the firefox errors...

Also, should i restart? it said i should before the driver would take effect.

EDIT: Gahhh, Civ IV isnt working either... can i just restore to a previous version? if so, how? x.x

Double edit: About to uninstall the drivers so they'll reinstall themselves. just wanna make sure... you're SURE this'll work?

gah, sorry, had to go afk.

uninstalling should fix the problem of firefox detecting two and like i said if it doesn't automatically reinstall then you can just run windows update and use that one.

oh restart before you uninstall or anything.

okay, one last thing...

theres no chance of a bsod if i restart, right?

Make sure to install the drivers that correspond to the correct architecture of your operating system.

what do you mean by that? o.o

32bit or 64 bit. i'm guessing you're on 64 bit though.
