Hi. My problem is on many games when I have vsync set to on my whole computer resets it, either upon the game loading or a short while into the game. Games it does this on are Sleeping Dogs, Far Cry 3, CIV V ,Watchdogs & Grid Autosport, amongst others. If I switch vsync off and leave all other settings as they were, on these games, I can play for hours without any issue. Games don't just crash or the computer freeze, it resets like I have pushed the reset button. Windows reloads back up, without any errors, such as disk checking and the computer just runs normally again,after logging back into windows. Not at pc now, but my specs are an i7 processor, 16gb ram, 6gb Titan graphics, on board sound, an Asus gamers republic motherboard and 2 x 256gb ssd drives. It also has crossair water cooling, the sort that has no maintenance required. The pc is hooked up via hdmi to a 43" Sony Lcd android smart TV. I never have any system problems when doing anything on the pc, it's lightening fast and everything is stable. Windows 10 on pc now, but same issues with Windows 8.1. Any ideas, thanks.
