Garrysmod Underwater Checkerboard color issue

[Nomad]

Hi, when i go play Garry's Mod and in some maps i go underwater, i can see perfectly fine but i see a black and purple checkerboard color when submerged. I Have hl2, hl2:dm, hl2: e1 and e2, TF2, L4D, hl2:LC, CS:S, Portal, Portal 2 (oh its unsupported...). I have pretty much most of the games, and they are all mounted for GMOD.

Sometimes as well, i will be able to see in the water except a transparent black and purple texture is above it.

I have ran those games at least once, i have tried the texture fixes but to no avail. What should i do?

here is a ingame photo of what i sometimes see
