Question GreenLight blinking on Motherboard

[Zi-shan12]

I moved my cpu from one room to another and then it started to shutdown on it's own, and then it won't turn on until i mess with the power cable. After some time the cpu won't turn on even if i do something with the powercable then I opened the cpu and cleaned every part of it. After reassembling it the shutdown problem is no more but there is a green light blinking on my motherboad. Please tell me about this greenlight and how to fix it.

these are my system info

Welcome to the forums, newcomer!

If you're referring to the LED's located near the ram slots, to the right, they are diagnostic LED's. Refer to your motherboard manual;

page 17,
and look closer at the motherboard's PCB to identify what name shows up next to the LED that's blinking.

You forgot to mention the make and model of your PSU.

Hi, I think I was mistaken It's the led on SSD that's blinking. Can you confirm it?

Here are some photos

Also is there any way to find PSU make and model using a software? Otherwise I have to open the whole system again to check it.
