Try adding in your launch options:

-dxlevel 80

to drop the dxlevel down and see if it helps.

How do you do that

[Dog]

Right click on CounterStrike: Source in the Games part of Steam.

Click on Properties....

Click on Set Launch Options

In there add:

-novid -dxlevel 80

and click OK.
This drops the DX level to 8.0.

You could try other options as well such as

-novid -dxlevel 81

whcih sets DX level to 8.1

-novid -dxlevel 90 -width 1024 -height 768

which raises the DX level to 9.0 with a screen width of 1024 and height 768.

Play around with various settings until it is stable.

BTW, -novid turns off the video when you start up the game.
DX9 has better quality of graphics compared to DX8 or DX8.1
What is your graphics card?

I have a nvidia geforce 7300 video card
