I just built my new PC and installed OS windows 10 64 bits.

my spec:
CPU: Intel Core i5-6400
PSU: Seasonic M12II 620 Watt
GPU: MSI Radeon R9 380 Gaming 4GB GDDR5
RAM: Kingston HyperX FURY Black DDR4 2133MHz 8GB

while playing a game after 15 minutes I got a black screen.
I turned Off the PC and after that turned it on again and there is no signal from graphic card. from the HDMI and from the DVI

I updated the bios to boot with the on board display and it was OK.
I checked the graphic card on other PC and it worked OK , so the GPU is OK.
I cleared the bios and updated it to last version but I still get "NO SIGNAL" form the GPU.
I checked that the GPU is seated OK and all connectors are connected OK.
Again every thing worked fine till I started play a game.

right now if I boot from the graphic card I am getting "NO signal".

the Windows recognize the AMD graphic card.

I am asking for your support.
