client wont connect to lan server

[ckob]

Ive got one computer that wont connect to my server over lan I have 4 computers and 3 of the 4 will connect for some reason when I try to connect to my server ingame it starts up the game then goes to the games intro and main menu hope someone can help...and yes I did search for this already.

are you getting any error messages from the server?
its not a newer/older patch then the server, right?

nope I dont get any error this is what happens

i click on my server in the server list ingame and click join

the game exits out and loads the game client but then blinks and starts back with the intro ,splace screen and boom the main menu again but if I try to connect to any other server it works fine. I know this is some sort of hardware issue atleast I think it is I was just wondering if anyone knew
