Thanks for the reply. Im 110 % sure its not a heat issue. My rig is water-cooled,I can run this game for 8 hours straight and both my cpu and gpu will never go above 55 deg. I have try all NVidia driver for the last 6 months with no results. I have stress this my pc inside and out, from intel burn test to memtest. U name it I have try it.Its all happen at random times.Im more feeling its FFXIV that's causing the issue. When this happens and screen freeze. I would be still on team speak and my party/FC member can see the red bar next to my name as if im lagging out. I don't know if b/c of my freezing it can act as if im lagging out which in term can put the red DCing bar next to my name. Its annoying as heck since it happens so random.
