My Screen goes blank and then recovers from time to time lately

With my Samsung R580 "touch of red" notebook' the Screen goes blank and then recovers from time to time lately.
When it happens it goes blank for a few seconds, then I get a message that the Display driver has quit responding and recovered
or similar message. Then the screen comes back on.
Does this mean the driver is bad or is my dedicated GPU going bad?

 

1. Have a look in Event Viewer > System Log which might give some info.
2. Check for a newer graphics driver.
3. Check the temperatures. Run HWiNFO > Sensors and set it to logging the readings to a file so you can check afterwards.

I have the most current driver. So I rolled back to the old one and I mean it was old as the resolution was not good. Then I reinstalled.
Now I'll watch what happens.
The temps show:
High was 59C for I5 and system.
High was 39 for GPU

What's normal?

 

I am having the same issue with my Samsung r580. I have random pixelation and had to boot in safe mode and disable the 310m driver in order to get Windows to boot to a clear desktop. Display driver NVIDIA Windows Kernel Mode Driver, version 188.64 stopped responding and has successfully recovered.

 

59C for the CPU temperature on idle looks OK based on my experience with other Samsung notebooks. The GPU is surprisingly cool.

I would be looking for full load temperatures below 90C for both CPU and GPU.

What would be the high temp side to watch for? 90C?

 

More than 90C is getting uncomfortably hot. Newer Intel CPUs are set to start throttling themselves at 95C.
