PC activates and then shuts down.

I built a PC for my wife and installed everything. It functioned well for a couple of days. Then she used it one day and it would turn on and off—either after a short delay or immediately. I’ve checked for issues but haven’t found a solution yet. Please let me know if you have any suggestions.

Maybe the overheating is a concern. Have you applied thermal paste or removed the plastic from the cooler's cold plate?

I completed everything and it remains unchanged even when trying to power it without the GPU connected.

It won’t stay on even after being left on overnight, so it doesn’t heat up much.

It might be a power supply issue. It seems strange that it restarts on its own.

It wasn’t on my mind before. The issue might stem from excessive power draw or voltage spikes causing a fault. @nathnbexs, could you provide details about your CPU, motherboard, GPU, and power supply?
