When I click the shortcut to run TATW, my computer just hardlocks to the point where nothing responds and the only solution is to hold the power button to shut it down. I've tried clicking the .bat file in the main folder and the same issue happens.

Same issue has happened to BFBC2 but other games run fine (Witcher 2, Medieval 2 kingdoms)

Specs:
Intel i5 2500k
2x2gb Vengeance RAM
Ati Radeon HD 6890
Asus p8p67 motherboard

Is there any diagnostic program that I could run to help you guys out?
