PC restarts in Oola's Workshop

During the quest "The Elusive Golemancer" after opening the first door with a Worker Golem my computer restarts, this has happened every time I do this quest, I don't have any other problems with my pc or anywhere else in Guild Wars, so it has to be something in GW.dat, should I reinstall it?

its probably a glicth in the game, send a ticket to anet and they should fix it
