Team Fortress 2 Gibs crash my game

When I spawn Team Fortress 2 gibs in Garry’s Mod, the game crashes. I have no idea why it keeps happening, it only happens with the gibs. Has anyone else ever had this problem, and if so, how do I fix it?

Specs. Please. I could help. With Specs.

your graphics card may not be able to handle the gibs.

Windows 7 Professional 64-bit
3.00 GB RAM
NVIDIA GeForce 9800 GT
512 MB Dedicated Graphics Memory

I can run TF2 on high settings without any slowdown whatsoever, and the gibs there do not crash my game, so this is very unusual.

It could be Windows 7

The same thing happened on Vista(which I am happy to have stopped using. Worst OS ever).
