This can literally be anything.
If you have overclock start in advanced and remove all the overclock including the program for GPU overclock. I had this before and it was the afterburner which forced my card to clock. Every time I started playing something it failed after 15-20 minutes and PC restarted.
It can be a ram that's failing when you're browsing if you don't have enough ram. A friend of mine had this with 4 GBram and chrome full with 5120312 tabs. PChandled it max of 10 minutes and went restarting.
It can be an old hard drive that shuts down after you start using it. For example you have a game or program installed on it, and PCis doing great. Then you use this program installed on this drive and it jumps to BSD.
My theory is, if it is not the graphic card you should see a blue screen of death. If it IS the graphic card you cannot see it because your monitor is connected to the GPU. Meaning , you get a blue screen but you can't see it cause it's all black. Then the PC restarts.
You can know if that's the case after troubleshooting. Just plug the monitor in a motherboard slot and see what happens. If it's the card you will know. Then I suggest you clean it good from dust and shit, it can be overheating or a malfunctioning fan. If it still fails, put it in another slot, it might be the motherboard. If that fixes it you either use your low bandwidth slot 8x PCI-E or you buy a new mobo. If it's not then again, might be the overclocking software that makes an unstable clock to it. As I said, just go advanced boot, reset the clockspeed , delete the software and try again it might work out for you.
If it's not the GPU and you are still getting those restarts it might be a bad/old thermal paste that is overheating your cpu after 20 minutes of work. Depending on your system to be honest. It might also be an unstable clock that is forcing the CPU to work too hard and produce too much heat.
If you are using a laptop , then sell it and buy yourself a pc

cause it most certainly is a thermal problem.
