Have you tried updating your video card/graphics card driver/s?

Edit:

You can also try posting here Team Fortress 2

Might find someone that's had the same issue & may be able to help better

You can set the graphics to their minimum settings and if this does not work then you definitely need to upgrade your GPU CaNNiBoWel. Also, make sure that your machine is well cooled if you are planning on upgrading your hardware.
