The problem with your Antec CPU is that it fails to start after the most recent shutdown.
I have an Antec CPU which failed to start after the last shutdown. The start button doesn’t work; only a small white light on the graphics card is on, and nothing else functions. It looks like the SMPS might be the problem, but why would a white light appear if there’s an issue? I even tried using a hot air gun to dry it out, but it didn’t help. Anyone can help me understand why it doesn’t start?
A white light doesn't mean the PSU is working properly. It basically just means there's some amount of +5V power. Nothing more.
I'd want to know a lot more about what's going on with this PC. Like what the parts are -- you tell us nothing about them -- and whether the event that made this PC look like it was in a car crash was something that preceded this. Running around with a heat gun randomly is not a way to fix anything PC related.
I'm not familiar with a car crash, but this resembles the image from when I viewed it 😅. It's an Antec NX291 cabinet equipped with an i9 processor.
The Antec Atom B650 is a garbage unit that I don't suggest using in any system with a dGPU. The CPU cooler you're referring to seems to be a model with a very small 92mm fan, which isn't sufficient for keeping an i9 cool.
