I have the Sapphire Nitro R9 380 and once I install the drivers for my graphics card there is no problem what so ever and then I do the restart and I try and launch one of my games (the game is not the problem) in the loading screen it crashes and restarts. I have tried to install the reinstall the drivers and it still happens and once I log back in the crash can can happen at any moment and it starts to happen when I even open Google Chrome and sometimes it restarts it can't reboot so it will crash straight after the crash and it would keep happening till I would hold the power button in to turn my PC off.
Can someone please help me and solve this problem.
