Basically while playing some games the entire system would freeze, I couldn't do anything and holding the power button didn't work either, I would have to pull the power cable. I noticed this happen a few months after buying the 3070 gpu, but I wasn't really sure if the gpu could cause this to happen. I decided to have all the temps and clocks on my second monitor so I could spot some kind of anomaly during the crash, because my screens stay on and frozen, but temps were all low and nothing weird.

So the game I was playing back then was stalker gamma, I decided to turn down the graphics to about medium and never experienced a crash again, so I figured it had something to do with higher graphic settings, but a few weeks ago it froze for the first time ever on CS2. Then it happened a few more times, and I noticed it was only when a molotov was thrown in front of me. But it didn't make sense, because I play cs with the lowest graphic settings, and I've had hundreds of molotov's thrown in front of me, it only started happening now. My system never did this until I installed the 3070, but even then, it seems like it's completely random. There's no error code on the mobo, my computer doesn't even act as if anything went wrong when I reboot.

My main questions: Is it possible for the gpu to do this? How likely is this to be the gpu's fault?

EVGA is the brand of the unit while 850W is the advertised wattage of the unit and Gold is the advertised 80+ efficiency rating. What is the model of the unit? How old is this unit?

If you think the GPU might be at fault, try and source(borrow, not buy) a reliably built PSU that has 1KW of power for the entire build and see if the issue persists. If it persists, then try and use DDU to remove all GPU drivers(Intel, AMD and Nvidia) then manually install the latest GPU driver sourced from Nvidia's support site in an elevated command, i.e, Right click installer>Run as Administrator.

BIOS version for your motherboard?

My bad, its an evga 850 G3, I wouldn't be able to get a psu from anywhere other than buying one, and I did use ddu already to clear and install the latest drivers, it made no difference. Bios version is 2606
