Everytime i try to execute a game a green letter message saying "Turning on" shows up after a few seconds and reboot my computer. What is going on? I tried to reinstall drivers and change some configurations. Please help me.
OS: Windows 7 - 64 bits
Processor: AMD Fx8120 Eight Core Processor
Graphic Card: Sapphire Radeon HD 7770
Power Supply: ATX 550w
The problem appears two days ago. A week ago i update the drivers of the graphic card, but the first days i played games normally. I didn't change any configuration before the problem shows up.
