Thread: Freezing problems

I haven't been able to find any answers anywhere else, so I was hoping you guys would be able to help me.

Last night TF2 began freezing on me after playing for a little while. This hasn't happened at all before last night, so I'm wondering what's going on. After playing for, I don't know, anywhere from 15 minutes on into the game, I'll just freeze and the sound will loop. I can usually get out of this by hitting the Windows key, and from the desktop I just kill the TF2 exe with Task Manager.

The weird thing is, I'm still sort of in game sometimes when this happens. If I go to the desktop and try to bring TF2 back up, I'll hear everything people are saying, and I can still type to people in game. I can also fire my weapon and reload and still hear the sounds, but all I'm able to see is the desktop.

I've verified the game files, but it got stuck at 100% for a while and I just cancelled it, because I figured that probably wasn't even the problem anyway. I thought maybe my laptop was overheating, but if I go back into the game after I freeze, it waits a while before doing it again. I figure if it's overheating, it'll happen minutes after I'm in the game. Last night was the first time this has happened, but it's done it every single time I've played for any decent amount of time today, so I'm wondering what could have changed.

If you guys have any idea of what's going on, please let me know, I'd appreciate it.
