Hello, I bought MSI GTX 970 Gaming 4g X from second hand shop around 2-3 months ago, it worked really well until today.

When I woke up and turned on my pc I was greeted with loop of "Windows didn't load properly", so I reinstalled my Windows 10, and when I started to boot the computer random flickering, lights and artifacts. So I unplugged my gpu and plugged hdmi into mobo : Windows loaded normally. I've checked what others had to say about the problem , apparently it was smth to do with drivers, but I couldn't install drivers if my gpu was unplugged, so I plugged my gpu once again, but now in bios chose to boot with onboard graphics : System booted, but whenever smth would use (even slightly) GPU , for example : when installing drivers or loading MSI Afterburner, my computer would freeze and the only way to restart it was with reset or power buttons... After googling and searching for answers I thought Why won't I swap my GPU into another slot - so I did. It WORKED!
I installed drivers, rust and went ahead to play it. After playing for 1-2 hours I closed the game and after 15-20 mins of idling I once again opened rust and whenever server would load game would start lagging after 10secs of gameplay and then my pc would crash. I thought it was rust problem, but NO - after playing forza horizon for 20-50 secs greenish screen would appear same happened when I opened furMark for once again 10-20 secs... Does anybody have a clue what could be wrong with my pc?
