Ok, this happened about 2 - 3 months ago. My computer first auto restart for god knows why when I'm playing The Witcher 3. But it restarted without a blue screen which I find it weird. And then after a few weeks, it restarts more frequently and after a few more days it happens everytime I start a game, exit a game, go into a new area in the game. I didn't get this problem before, even my old games start to have problem. So I'm assuming its not the program's problem.

And yesterday I went looking for solutions online, and cannot seem to find any that will solve my problems.
I tried using HWMonitor, stress test my GPU and CPU and checked everything in BIOS, checked my MOBO and made sure I didn't use any overclocking and everything was at default. But everytime I stress test my GPU, it won't restart but until I click the [X] to exit the test, it restarts my computer.

I installed all the updates of my GPU, double checked in the device manager and everything seems updated to the newest drivers. And that didn't work. After that, I used DDU to uninstalled every software related to NVIDIA ( drivers, PhysX, NVIDIA Remote etc...) and still didn't work. Still restarted.

Checked all the voltage and heat with HWMonitor and everything is all right, Temperature wasn't too hot. But there is a catch, it doesn't reboot when I start up my computer after "SHUTTING DOWN" the computer, but it will reboot after 5 hours++ of using it.

I took all the components out from the PC, cleaned it carefully without using water, just blowing air from the air tank or whatever it's called. Placed it all backed in and still doesn't work.

I even tried to reformat the PC, it works all right the first 2 days then after that, same thing happened. And with Kaspersky Anti-Virus didn't find any virus in the system as well.

I don't know if I did anything wrong or I did everything that I can do but I hope you guys are willing to give me some solutions and answers. Feel free to ask me anything you wanna know to what I did to try to fix my PC. I don't recall if I left out something.
