I have a PC which I built about 2 years ago and it randomly restarts without warning, only when playing graphically intense games or during intensive cutscenes. Smaller games like Orcs Must Die or South Park or just surfing the web will never cause a restart, but Mad Max or Witcher 3 will.

CPU: AMD FX-8320
GPU: Gigabyte R9 290
PSU: 600W Corsair
RAM: Crucial Ballistix 8GB
MOBO: AMD, not sure beyond that
OS: Windows 10 64-bit

I have checked multiple issues already:
- It's not the CPU overheating
- It's not the GPU overheating
- It's not the power strip or outlet

I have checked the event log and it's showing the restarts but I'm not sure what the problem is, there's nothing in plain English. I am not very computer savvy when it comes to building and stuff, so if you have any suggestions try to keep them simple.

During cutscenes or gameplay, my PC will randomly restart. No beep, no BSOD, just restarts out of nowhere as if I pressed the restart button. There is one particular cutscene in Witcher 3 which triggers it in the same place every single time. It is driving my mad and it has been going on for months now. I'm at a loss and I have no idea what to do in order to fix it.

I had planned on switching to an Nvidia GPU soon anyway so I ordered one and am hoping that will fix it. Replacing the PSU is my next stop and replacing the CPU after that. Please, if any of you have any suggestions or know how to read the error messages in the event log let me know, it would really bring down my stress level. I just want to game!
 
If you're not overheating, then it's likely you have a bad power supply, or at the very least a power supply that can't deliver the needed power for your setup. The Corsair CX series PSUs aren't the greatest, and a CX600 could potentially be taxed too much with an R9 290 and an 8 core FX CPU, especially if either or both are overclocked, both components are pretty power hungry.

I'd say try replacing the power supply before swapping out a graphics card. An Nvidia card might solve your problem, simply because it uses less power than the R9 290, but it might not if the power supply is outright defective and can't put out the wattage it's rated for.
