[SOLVED]Everyone times out when I connect [Gmod]

[irontires]

Im running a Garrysmod dedicated server off of my computer . When I connect to it, everyone that was currently on my server times out. They then cannot reconnect to my server for at least 5 minutes because it shows that my server is not responding. Ports are forwarded and open. After that first not responding session the server runs fine with no issues until I change the map, or restart the server. What could be causing this issue? Any help would be greatly appreciated!

Also I have a few people that when they connect to my server, they sometimes get stuck on Retrieving server info then their game crashes.

Well, when you connect to a server your computer probably freezes long enough for the server to stop responding, thus everyone accept you loses connection.
