This started happening a couple of weeks back. The issue is intermittent. Whenever I'm playing a game, the PC automatically restarts. Sometimes it happens within 5-10 minutes. Sometimes I can play for hours without any problem.

I've already ran memtest and prime95 and didn't face any problems with either RAM or CPU.

I've mostly faced this problem while playing Sniper Elite 4, but on couple of occasions it happened while playing Destropolis - a rather lightweight twin stick shooter.

Earlier this month I was playing Spider-Man without any problems.

Now I'm wondering if the GPU is going bad or if the PSU is going bad and is not able to provide enough power.

Is there any way to conclusively understand which component is malfunctioning before I can start the RMA process?

You say you have 4×8GB RAM. I had an issue where I had 2×16 GB for sometime. Later, I wanted to upgrade and got another 2x16 GB of the same RAM for a total pf 4×16 GB and my system started to randomly reboot. Taking out the two new RAM sticks stopped the random reboots. Some RAM manufacturers recommend using RAM from the same package (i.e., for the same 4x8GB, all 4 sticks should be packaged as one). If the above is your setup, I would start by installing the RAM that came within the same package and go from there. If you want to have 32 GB, I would recommend installing 2×16GB. Also ,keep in mind that it is highly unlikely that your CPU and/or motherboard supports quad channel RAM evening you have 4 slots for RAM.
