Server Loading Issue

Okay,

When i click on a server and join it it downloads the addons and then freezes. My computer can take garrysmod and i have been playing it on this computer for a long time. I dont know why it just randomly stopped fully loading servers.

Once i wait for like 15 minutes i try to cancel it but its frozen. So i control alt delete and bring up task manager and end process but if i dont do it fast enough it freezes my home screen and i have to force shut down my computer.

Any Ideas? I already uninstalled the game and then re installed it.

Thanks,
RogerB

Bump - Anyone know the problem?
