Question Power LED stays on after shutting PC down

[lukas9936]

Hello,

I recently built my first PC and everything seemed to be working. But today I ran into a problem I can't find a solution for on the internet.

Whenever I shut my PC down, my Power LED on my case shuts off and then less then a second later the LED will light up again (my PC does not turn back on or sth like that).
Sometimes the LED will start by flickering a bit at first, but it will always go away after a few seconds.
Also weird: if I completely shut my PC down by turning the power supply off manually and then turning it back on - with the built-in switch - then the Power LED will remain off.

Now I am not sure if I should be worried about it or not, but my PC did not do this the last few weeks.

What I've tried so far:

• Turned fast boot in windows off
• Checked if any cables were shorting to my case; none did
• Removed the Front Panel Headers for the Power LED - LED turned off - and pluged them back in - LED immediately turned back on.

I'd super grateful for any help or advice,
Lukas

try changing the polarity. unplug the LED, flip the plug, plug it back in.

Hmm, when I do that the LED just wont do anything at all, it just stays dark (even when it is supposed to be on - when the system is running)
