My pc restarts when playing games(AMD Radeon (TM) R9 380 Series)

[Jerik_]

Hi people of Earth.
I have had this problem since I first built my computer a few months ago. My computer restarts after a few minutes of playing any game. At first I though it was rebooting becouse my CPU was running a bit hot ( 75C) so I bought a aftermarket CPU cooler and now it dos not overheat under loud (50C-60C) and it still giving me the same problem. Then I downloaded FurMark to test my GPU AMD Radeon (TM) R9 380 Series which runs at a temperature of 75c under loud and it crashed after 8min. I have tried uninstalling and reinstalling AMD drivers, installing updated drivers for my motherboard, running games at different resolutions (4k,2kand 1080p) and installing new fans ( I don't know if it is relevant but I us SpeedFan to control my fans) and none of thees fixed my problem. This card is bran new and I do not know why this is happening.

I have windows 10 pro

Gigabyte G1.sniper H6

Intel(R)Core(TM)i5-446 CPU@ 3.10GHz,3201Mhz,4 cors, 4 logical prosesors

8.00GB of RAM

1TB Disk drive

And a 600W bronze sertified power supply

Thank you from the bottom of my hart fore whoever fixes my problem and thanx for taking the time to read this.

Try a BIOS update.
What is the brand and model of the power supply?

It may simply be a bad card if you have a good PSU.

my power supply is a EVGA 600B
I have updated my Bios to the latest version. Now it takes more time to restart but it still restarts.

My guess is most likely a bad power supply if not then next most likely a bad graphics card

EVGA 600B isn't a good PSU. Most likely the cause of the problem.

How hot can my AMD Radeon (TM) R9 380 Series run safely. Recently it has been going up to 80C and I don't know why. Is this what may be causing the problem?

 

[chimera201]

80C is typical for GPUs at load. That isn't a problem.

Does it update on restart?

 

[Jerik_]

Some times but it usually just restarts.

 

[FlayThenHook]

If it updates, theres a setting that ask how you want updates to be delivered.

Thanx to everyone that helped. My new power supply came today and so far so good.
