White Line Splits my Screen Diagonally

When I play, there is a white line that splits my screen in half diagonally. This happens instead of the crosshair showing. This could be related to some missing textures. I would like to reinstall as a last resort, it took almost half an hour on the first install (though I wasn’t torrenting…). Please help.

Directx issue:

Your pc has installed an old version of directx.

Check if your GPU supports directx 9.0, if yes download it.

If no try to uncheck the post processing on the hud, the bloom fx and lower the graphical settings (for instance HDR antialiasing etc… )

If you google your problem, you’ll find that is quite common, especially with SFM.
I’m sure that if here you won’t find a solution, something will pop-in with a simple search.

No, that was me setting the DirectX version to 8, thinking it would give me a performance boost like it did in TF2. Thanks for the info.
