I have brought L4d2- Four pack so that i could play with my friends. However, it seems that i could not play L4d2 for some reason. Everything work prefectly untill after the loading screen. Once the loading screen is done, my screen starts to blackout and some random noise can be heard from then background. However after a few second or so, my computer auto restart itself. i have tried reinstalling L4d2 but it doesn't solve the problem.
