Since yesterday, when I'm in a game (in this case modded Minecraft), my monitors will randomly disconnect/black screen after a few seconds when I'm in game (a server in this case). Today, I've done everything I'm able to do to try to fix the issue. I've uninstalled and reinstalled my graphics card drivers and Windows updates and some other things. Nothing has helped. So now I'm at a point where I think it's my graphics card being defect, or my power supply isn't good enough. I got my graphics card in March 2025 to replace my on-board card. Was having issues at first but changed the settings and it has been doing fine until now. The power supply gives 550w, and my graphics card requires 550w. I've always found that risky but a year ago when I asked tech support it said it should be fine for now, with maybe need to get a new power supply in the future. The graphics card I have is a GeForce RTX 3060. So I'm wondering, is my graphics card defect or do I need a better power supply?
