GMod crashes when I join a second server or exit game

[GordonZombie]

When I join another server after being on a server, or exit gmod after being on a server, I get a "hl2.exe has encountered a problem and has closed", is there any way of fixing this, as I have already uninstalled and reinstalled the game via steam. My graphics card is an Ati Radeon Xpress 200 but I will be getting a new one soon. My gmod plays smoothly in game but I need this problem fixed. I have already increased my virtual memory, could someone help.

Can sometimes be when you have a lot of addons, try clearing out addons folder and try again.

No, I will have toinstall all my addons. I even sent Garry a pm but he never replied. Please help.

If that doesnt work, Try lowering your settings.

I'm getting a new graphics card and RAM soon, will that help?

Oh, and will that mess up gmod?

[Goz3rr]

It shouldn't, But if it does, Just remove the parameters :P

After reading your post again, I though it might have something to do with addons, Try joining a server, Disconnect, And join that server again.

If I join a server, then join a server again, gmod crashes.
