Its a urgent matter please help. When I am starting a game say metro 2033,Enemy front, etc, after playing for sometime my display goes off. Though when I am playing fifa14 nothing happens, runs smooth for hours. When the problem happens I have the only option to restart the pc or shut down. It's a very weird problem, I have tried every possible way, I checked the connections, cleaned the dust, formatted to win7 64bit, nothing helped.
My configuration
sapphire hd 7770 1gb gddr5
8gb ram
Core2duo 2.80ghz
Please help
