White Box Problem?

[US_Skinny]

On any map I see some white boxes, they look like light entitys because they are around any light on the map. Does anyone know the command to stop them from showing up?
I noticed this happening when I started using the DX7 insted of DX8 because it kept my game from crashing. It doesnt hurt anything, just a big bug that is distracting.
My specs are: AMD 64 2800+, GF4 TI 4200(May be the problem), 512 PC3200. Ill post a SS if anyone wants.

I get the same problem the thing I do to get rid of them is to switch DX mode ingame. like start in DX 7 in the game then switch to DX 9 and then back to DX 7.

Whats the command to change it in-game?

just go to console and type Mat_dxlevel 80 or 8.1 then go back to 70
