The game crashes after playing for about 5-60 minutes on any server. This is happening for about a month now.

It seems that the time it takes for the game to crash depends on the number of players on that server. I played for an hour on an empty server before it crashed, and 5 minutes on a full one. Maybe its the number of players near you.

There seems to be a pattern that takes place before each crash. First the screen freezes but there is sound. then the sound stops. then the sound comes back for about 1-2 seconds. then the sound stops again, and the game crashes.
This pattern only happens when the game is about to crash.

I've done everything from updating drivers to reformating, reinstalling, checking desktop composition, i have a good comp. Not overheating.
