Fire, Blood, and Swep icons not working!!!!!

I can see smoke and hear the fire noises when I ignite stuff, but the fire doesn’t show up! When I first got Gmod it did, but now it only does once in every hundred times I play it.

It’s the same problem with the blood too, but I see tons of little red squares instead!

Also, with Sweps, I always see a little piece of paper (script?) instead of the icon for it at the weapon-switch scroll thing at the top.

I have the Orange Box, HL2DM, and CS:S Blood and fire work in all of them but EP2 and I’m not even sure what it’s supposed to look like in TF2 (Glowing orange blobs surrounding their bodies??).
