Custom sounds yes..
Running game at 1024 textures..
Resolution 1024X768
This is what usually happens when I lockup. It is very random remember. The screen will freeze, sometimes my desktop mouse pointer will appear and I can move it over my frozen AH screen. I can hit any random button on the keyboard and you will her the "dunk" sound, like an invalid keystroke. In order to get rid of the locked screen, I have to hit the power button on the computer. Sometimes, I need to hit Ctrl+Alt+Delete to get that pointer I was talking about to appear. I've only got 19 processes running, just the vitals to keep the computer stable.
I guess I can try running the game in 256 textures, but Im sure it will lock running that too.
