CPU debug LED

[Kei_Li]

Hi guys, need some help here if possible please.

Recently when i power up my PC, it won't boot up normally and the CPU debug red LED will light up. I have to press the reset button on my PC before it will get back to booting normally into windows 10.
I do a normal shut down and try to power up again, same issue.

Interestingly, if i unplug the power cord for a few mins to drain off the power, plug back in and start up the PC, it will boot up just fine, the CPU debug LED won't light up.
But if I do a normal shut down and try to power up again (without unpluging), same issue happens.

I have turned off "fast start up" in the Power Option.

Using a MSI B450 Gaming Carbon Pro AC, with Ryzen 2600x.

Anyone know what's wrong?

My older PC had something similar, and a change of PSU fixed the issue, however i'm not 100% sure.
