About six months ago my computer started shutting down suddenly at night or during the day, even though I wasn't using it much. At that time, Windows 10 was already installed. It keeps restarting sometimes, or it just freezes on the screen with nothing happening after. I thought upgrading to Windows 11 would help and fixed nothing. I tried looking in Event Viewer but couldn't find anything useful. Any help is welcome! The PC uses an ASUS TUF GAMING B550-PLUS motherboard and an AMD Ryzen 7 5800X processor with 3801 MHz speed. It has an NVIDIA RTX 3060 GPU, PVB432G320C6K RAM in two sticks, a Samsung 970 EVO Plus for one drive, and a Samsung 840 EVO for the other. I have already tried changing power cables and reinstalling Windows 11 from scratch. I don't know how to read logs or check anything else besides Event Viewer, so any help would be great.

Was the issue still there when I changed the battery?

Yes, the computer still turns on when I swap out the old power supply for a newer Thermaltake Smart 750W 80 Plus unit from another PC.
