Can't change my aspect ratio in CS:S

So I can't seem to change the aspect ration from 4:3 to 16:9 anymore in CS:S. Whenever I do change it, it reverts back when I hit apply or ok and check it again. The screen now is a square in the middle of the screen with a black border on both sides. And thoughts?

Never had this kind of problem before now...

the only thing I can think of is reisntalling your CSS!

Did you do anything special to your computer recently?

Check your video drivers

yeah thats right, just can't be a fluke in the software itself :/

I would go to the video card's control panel and set everything to default and see if that was it.

[my approach is more time consuming obviously!]

Yeah... I figured it out a while ago... I'm surprised you guys brought this back up after like 2.5 months. It was a problem in the control setting of my Nvidia driver. I fixed it.

I didn't look at the date lol! gotta keep my eye on that!

It's Haplo's fault!

what did he do?
