Temporary (Listen) Server help

For about up to 7 minutes after my server starts anyone can join and my server will be fine but after 7-10 minutes when i see “__________ has joined the game” the game will freeze or it will go back to the main menu and freeze. I can’t even CTRL+ALT+DEL to end garrys mod so i have to restart my pc. If anyone could help me it would be nice.

How many users are there when that happens?

I usually have 1 or 2 on (because it’s not a popular server) and then they join and crash it :confused:

Try reinstalling Gmod, or atleast cleaning it. If that fails, try scanning for viruses, or unwanted spyware. If not still, or computer might need a tune up.
