Wierd Problem

[Hellfire1190]

I have this really wierd problem. Randomly only when i join a zombie mod/horde server my game will crash. It either wont load the server and freeze up or it will load the server i will play for a little while then the screen freezes and whatever sound was being played at the moment starts to play in a continuse loop. Theres no telling when it will happen either, and the only way to fix it is pull the plug on my computer (press the power button) and manula shut the computer down. Someone please help. If it happenes again i can see if i can post some sort of error message if any pop up.

I'm not much into technical problems, but something like that used to happen to me in Gmod and on CS:S when uploading it from Hammer. I reinstalled Gmod, and it was cleared. (Most likely a bad file you got from a server, buddy.) And for the Hammer solution, I have no idea if it works now, I just save my maps into my CS:S map folder and go to create servert o upload them. All I can say is reinstall to something like that, maybe someone else on the forum knows what's happening to you.

Sorry if I couldn't help,
