There are only old posts with this topic but they are quite old. Since upgrading to Y18 the sim freezes and sound loops in the middle of a race (reboot is only way out). I haven't been able to see a pattern yet, but it always happens when I am in a cup/series race usually featuring quite a few cars and when it's important that the game is stable.

My setup is:
CPU: Q6600 (not overclocked) - no overheating issues
MB: Asus P35-DQ6
Mem: 4GB
GFX: Nvidia 9800GTX
OS: Vista x64
Wheel: G25
Sound: Motherboard sound

Any thoughts on how to troubleshoot this?

Whats your PSU?

Do you get this in other games?

It's a 620W Corsair, I made sure I spent decent money on that just in case. No other games freeze like this which I find odd if it were to be a HW issue (Crysis, BF2, GTR2 etc).
