Hi, I recently swapped my power supply unit (PSU), and since that change, my computer restarts after just one or two minutes. It still works fine in those first few seconds, but then it crashes again right back to the beginning. This crash feels normal because all fans are spinning, not a total shutdown. Once it's restarted, everything stays up until I power off, and it won't go back on again until I turn it back on. My old PSU was 750 watts, and my new one is 700 watts, so the new one has plenty of extra power. When I switch to the new PSU, the fans spin a little louder for a split second at the start, just like when you put gas in your car right before it starts moving.

Even brand-new components can break down over time, so putting the original power supply back might still cause a problem.
