A few day Ago I was doing my ususal: playing Minecraft while i'm watching Youtube on my secondary screen.
Then suddenly the PC restarts. But this is the weirdest part: sometimes the PC restarts normally, but sometimes at the time everything goes to black the GPU fan goes crazy working at full load, and remains like that as long as the PC is on, then the PC starts with the integrated graphics with the default driver, and in Device manager says that the dedicated GPU is not connected to the PC. If the computer fells onto this state, rebooting keeps the GPU fan crazy and the integrated working. Only if I turn off completely, let it off for a few seconds and booting again makes the GPU "come alive". Other odd thing is that no blue screen appears at any time, and according to my readings the GPU temp is normal for the load (~65ºC).
I've tried to change the thermal compound of the graphics and installing the beta driver, but also the same.
This only happens when i'm gaming, browsing or working is fine, and this started just a few days, and I have this GPU since december, putting even harder workloads for long time on the GPU with no problems. And nowdays playing after a while gets me the restart,
I don't think is a powerr supply issue cuz my system uses like 260 Watts, and my PSU is 430 Watts.
And the blame of all of this mess is a Sapphire Radeon R7 250 1GB GDDR5.
