Help with steam, please

I am currently attempting to install and run Steam (Specifically for counter strike source, if it matters), and everything worked fine (as far as installation goes)... until i actually got to playing the game. I am able to enter CS:S normally, and the loading screen appears normal. However, once i am done loading, all of the text and the images are severely warped (To the point where they are completely unrecognizable). I also noticed that when i moved my mouse toward the right side of the screen, the screen seemed to "scroll over". At first i thought that this meant there was a problem with my 3d desktop, but disabling it did not help.

If anyone could suggest how to get this working, i would much appreciate it.

I have the same issue. I'd like to know how to fix it!

Firstly, what's Steam? It would help if we knew.

steam is a launcher app for valve games. its a distrobution method for purchasing new games also.
