Video Card Driver Help

[PCNoob2]

It seems like my GPU drivers are uninstalling themselves. I was getting an error whenever I tried to play Diablo 2 that said to please update my video card drivers. And I did. And it worked for like 3 weeks and now it's giving me the same exact problem.

I hadn't changed a setting or anything.

Does anyone know what may be causing this?

I'm getting http://www.blizzard.com/support/?id=adt0271p the error 25 one.

I updated my direct X. What do you think I should do?

reinstall the game, install the card drivers before the game

And the same thing is happening to my CSS.

I go to steam, I launch it, the screen goes black as it's getting ready to load, and then it all just goes to my desktop like nothing happened. No error message or anything.
