Half-life 2 And Source Video Problems

[crude]

i just bought a new ati x1650 pro 512 mb graphics card and updated the drivers....cheched the game cache and everything and the half-life 2 games and also the source games displays everything weirdly....the maps all messed up and the walls and floors become seethrough...i dont know how to fix it except maybe i should go with nvidia instead of ati......can someone please help me.....the only problem i can think of is maybe i didnt uninstall the integrated graphics card before upgrading but i dont think thats the problem.....i dont even know how to do that
I also forgot to mention that my pc came with 2 gb of ram and i added another gb of ram...do you think that could be the problem???? And 1 other thing....im using windows vista ultimate

I don't know how to edit my posts, as I can't find the button, but I have FIXED THE PROBLEM!!!
It turns out that I had to install windows XP drivers to get it to work with games. I thought I'd already tried that, but I guess not.

Finally I can play Source games with slightly better graphics!!

(BTW justincase3: Thanks for the help, even though it didn't help, but thanks for trying...)
