Disclaimer: I am a complete novice at building a pc. My friends recommended me the parts and my brother helped me put it together.

I bought a new graphics card (rtx 4060 ti) and a new psu, and everything seems to be working together for about a week with no issues. Two days ago my windows updated at night and I turned off my pc. Next day, I tried playing a game and 5 minutes into it my graphics card turns off (the fan stops spinning) and I get a black screen. I turn off my pc and turn it on again and the graphics card works but one of the fans start working then turns off. As soon as a start up another game the fan starts up for a second, then the card turns off and the screen goes black again. I stopped playing games for the day but other functions like zoom calls, browser, etc. still work despite one of the fans not spinning.

This morning, I turn on my pc again, and the monitor says it’s updating windows. A few seconds after that, card turns off and screen goes black without even reaching the log in screen.

I made sure to check the drivers were up to date, and they are. I don’t think it’s a psu issue since it’s new and it’s been working for a week before. I think it’s a windows issue but I can’t even access the log in screen now. If you guys can help I would be very grateful!
