Lose video output randomly then system freezes

My desktop lately will randomly blackout and lose video signal as if a video cable came unplugged. I will continue to have audio and be able to talk on discord for about 5 to 10 seconds. And then my computer fully locks up and nothing works except turning it off.

When it does fully lock up I get kicked from games and call so I know it's not just loosing audio and video.

It is mainly when I play GTFO though happened other times. It is a used graphics card ASUS TUF 3070 OC.

I have ran storage test and says my drives are healthy. I'm down to thinking it's a graphics card, ram or power issue. I have a 6mo seasonic power supply that I hope isn't the issue. But the wiring in my house isn't good (100yo house) so I thought about getting a UPS or power conditioner. I'm not popping a breaker though.

Normally it happens maybe once a week but today it happened five times in a row. I lowered the settings in game and nothing changed.
