[SOLVED] Power light is green on motherboard but system is not turning on ?

[pell380]

Last night I used my PC and turned off in the morning when I turned on my PC it was showing no signal I checked there was a orange light on mother board all fans were spinning showing a POST error.

I thought it's a GPU issue so I removed GPU then inserted it again. Now mother board power light is on but when I press PC case power button nothing is happening, system is not turning on, no fans spinning, and no RGB. On first start up there was just a display issue but now it's more than that 'cos PC is not starting up.

I tried to remove jump start PC nothing happens. Is it power supply issue or a motherboard issue ? How to check what it is at home before going to shop ?

full system spec? include brand and model of the psu

Usually there are LED's on the board to help with diagnosing the issue of a faulty hardware, provided the board isn't compromised. Not all boards have them which is why we as for build specs. Please list your specs like so:
CPU:
Motherboard:
Ram:
SSD/HDD:
GPU:
PSU:
Chassis:
OS:
Monitor:

If the PSU in your build has been in service for a while, please parse the age of the unit apart from it's make and model.

My PSU and GPU are used and old, all other parts are new. GPU would be like purchased when it was new it is my friend gpu who gave me after he switched to new GPU and PSU was bought in used as my old cx550 corasir was dead but it was on older PC. Then I bought this antec one using almost 2+ year but would be older than that.

Do you have access to another GPU to swap in for troubleshooting?

Not other GPU I have tried to remove GPU and then press power button nothing happens system is not powering up

The system lacks an integrated GPU, so it will not start without a working dedicated GPU installed. Swapping the GPU is the easiest way to isolate the problem.

What's the point of adding or swapping a GPU when PC is doing nothing on pressing power up button

Can you borrow a friend's PSU to test with? How old is your current PSU? It looks like your PSU has a 3 year warranty.

Earlier it was, from what you stated. Swapping the PSU is the other thing to check.

This sounds more like a problematic PSU than a problematic motherboard. Until you put a significant load on the PSU, even smaller things like an LED on the motherboard lighting up is not a surefire sign the PSU is OK.

Of course, having another system to swap parts and test would be better.
