Is my laptop GPU malfunctioning?

I've had this Sager laptop with a GTX 1060 for a few months, it's been running fine up till now, when I started getting random blue screen involving my video driver. Games started crashing to my desktop after 2 seconds of playing. I would play overwatch, and the second I load in, it would say "Your rendering device has been lost!". I would play Battlefield 1, and it would get Direct X function crashes a few seconds into the game. Elder Scrolls online is crashing the second the game loads. Counter strike will constantly freeze and my monitor would turn on and off.

So I spent the past few days troubleshooting, reinstalling the newest drivers, even reset windows, but I'm still facing the same issues.

I did a Furmark test, and it ran fine for a long time. It hasn't crashed on me.

I recently did a Unigine Benchmark while running GPU-Z to check for issues, it started freezing, and my laptop screen started blinking on and off, with "dead zones" in the GPU-Z log where it seems like my graphics card turned on and off. The GPU clock and load would spike, it would turn off for a split second, and turn back on. What does this mean?

Here is a screen shot of my log:

There could be many reasons, your GPU isn't properly using the VRAM it has to play games, your CPU could be dying, causing other components to fail, or your entire motherboard probably is starting to fail, plus check the computer temperature with different applications, its rare but there are cases when the application gets a wrong temperature reading, if you still can't figure it out, try contacting Sager or the manufacturers of the components.

I guess I have no choice but to send in an RMA, It's pretty hard to trouble shoot the hardware of a laptop. I just wanted to confirm if it's definitely hardware or not, thanks.
