PC Crashes in Gridania

Hi,

i'm having a serious problem,

Whenever i go near the Gridania Inn, i have a 50% chance that my computer crashes... My moniter goes black (as it had no input), pc is still running but no reaction at all. The only thing i can do is to force my pc to reboot.

Someone got any ideas why that is happening to me?
