This bug happened twice already in the past few days. It happens when I switch map. First, black screen and then after a few second PC reboots without warning.
I can play other games just fine, so I’m guessing it’s something related with guild wars 2. My graphic card is Asus R7 360, 14BG of RAM & Phenom II X4 945 processor.
Related issue: when loading maps, desktop will flash for a split second just when you’re about to load map 100%. I think this started happening with Ember bay update.
