System freeze at level start

[table]

The last two attempts to play the game have ended with a complete system freeze near a level start. I don't know the name of the level, it's the second occasion you're flushed down a pipe and enter the level from water. Crash #1, As I emerged from water - PC froze with sound looping. Crash #2, At immediate level start, still in water - push ball to proceed - PC froze with sound looping.

On both occasions I had to power down the computer with a long-press on the power switch. I've played virtually every FPS and FPRPG released on the PC in the last seven years on this machine without a single CTD, freeze or blue-screen.

Here's "Launch-backup-2010.11.30-23.51.28.log" (the last time I attempted to run the game):

I'm currently playing UT3, Bioshock and Singularity, all demanding Unreal engine games at my monitors native res and at full quality, without problems - my computer has never frozen before.

There is also a AllowD3D10=False right below, you may want to try setting that to True.

That won't work in Windows XP will it?

I haven't had any problems with the latest Unreal engine with UT 3, Bioshock, Singularity (a shovel-ware console port with texture streaming problems before the first patch) and the rubbish Blacksite: Area 51, Legendary and Turning Point. Steam and every Valve game works well and I even managed to play through Crysis and Crysis Warhead (very slowly) several times without a single freeze, blue-screen or CTD.

Only The Ball has ever made my computer freeze.

No that won't work on XP. Alot of the UE3 games you mention are old UE3 games though, you could try to run a new UE3 build and see what happens. You can download the UDK at www.UDK.com, it is basically a UT3 demo.
