computer crash after load

Whenever I connect to a MP server, I always get about 30 seconds into connecting or less, when my computer will just freeze entirely, stopping all sounds and keeping the screen frozen. There is no activity from my hard drive, and I have to press the reset switch to reboot it. Help?

Have you re-installed it? If not try it and i’ll try helping you out, sounds like a familiar issue.

ALSO is it to all MP servers?

Do you get this issue in singleplayer also? The fact that gmod crashes your computer is pretty drastic, most likely NOT a gmod issue, does this happen in other games too?
