I recently upgraded my CPU and everything was working perfectly yesterday. However, after switching to a new case and power supply unit (PSU), my PC won't turn on at all. I tried switching back to my old PSU, but it still doesn't work. The system powers up briefly with the fans spinning for a second before shutting down and restarting. Any ideas on what might be wrong?

It sounds like you might want to check the power requirements for your components. Make sure your PSU can handle the new CPU you've installed. Also, double-check that all the cables are properly connected—sometimes they can become loose when changing cases. If that doesn’t solve it, try disconnecting and reconnecting your RAM as well.
Good call on checking the power consumption! If you bought a PSU that's 100W over what you need, it should be fine. Just ensure all your connections are secure. Sometimes, a loose cable can cause these kinds of issues, so it’s worth a thorough check.
