white streaks across players in TF2?

[Doomcat]

im getting this glitch, where playermodels, and things such as sentries and teleporters, have white streaks across them. basicly im wondering how it can be fixed:

Update your video drivers.
Do you know what graphics card and operating system you have?

 

[Doomcat]

My video drivers are updated i think, i'll try updating them though...as for my graphics card and operating system? exept that my op system is windows XP i have no idea

EDIT: found out, my video card is an Nvidia 6800

just updated my drivers, no change D: please help, i CAN live with this, but if possible i would rather have un-streaked characters

Stupid question. Is it mad milk or is it constant? (I ask because my settings are turned down so low that I don't even know what most of the graphics are supposed to look like)

Specific DX levels might also have been affected by the update.

Using DXlevel 9.0, and no its not covered in milk, its CONSTANT (if you look at the screenshots >.>) and its STREAKS ACROSS THE BODY not a constant whiteness to the character.

FOR INSTANCE: when in the character select screen, i'll see the spy, half of his body is white the other half is normal.

this happened to me in dx 9 once, switched to dx 10, fixed problem
pretty sure its just crappy shaders

er...i dont think i have DX10 installed, and even if i did, im afraid using it will kill my FPS
