[SOLVED] MSI B460M System Stuck on VGA Led after shutdown, but reboot is working fine.

[arena7]

Hi, I have build this PC 1 month ago and it was working properly.

Build Specs:
MSI B460M PRO VDH WIFI MATX
Intel Core i3 10105F
ADATA - XPG GAMMIX DDR4 1x8 GB
Crucial BX500 250 GB SSD
Galaxy GTX 650 1 GB (Form OLD PC)
Antec VP450 Plus 450W PSU

I swapped the VGA cable of the GPU with HDMI cable and it was working without any issues initially and then the issue started, while powering on the system debug VGA led is turned on and then its not going into boot mode, so i have turned off and on the system several time on that day and it didn't workout.

After the next day morning replaced the HDMI cable with VGA cable and then when i power on the system it start normally without any issues and restarting the system also works fine, but when i shutdown the system and turn it on again it gets stuck into the debug VGA led turned on.

And its not working for the whole day and i have to wait till next day morning to start it and its started normally without issues then repeats the same like if i shutdown it gets stuck on the debug VGA led turned on.

Please guide me to diagnose the motherboard and its connected peripherals.

And below are things i have tired so far:-
1.Swapping the single RAM stick with other slots.
2.Cleared CMOS using the jumper pin.
3.Re-seating the GPU in the PCIE slot.
4.Replaced the old VGA cable with the GPU and removed HDMI cable.

Kindly help me guys.

I would definitely try a different graphics card. Buy one. Borrow one from a friend. Or, take it to a shop and have them test the system using one of their own cards. Given the very old age of your graphics card and the relatively new age of your other hardware, it's very likely to be a failing card.

It could however be a PSU issue as well. How long has it been since that power supply was originally put into service?

Do you have the MOST recent motherboard BIOS version installed? If not, it might be a really good idea to update to the latest version. The fact that things work again if you wait a while though tells me that something is either overheating or trigger protections of some kind, so that makes it a lot more probable that it's the graphics card or power supply in my mind.

@Darkbreeze Thanks for reply man.

Will definitely try a different GPU and the PSU was started using from Apr-2021.

Motherboard Bios version: 7C83v14 and they have released a new updated version 7C83v15.

So then, pretty unlikely to be the power supply. Still possible, but probably not as high on the list as the graphics card, which is very old.

If you can update the BIOS just to eliminate that possibility, probably a good idea, but I suspect that this is definitely due to the age of the card.
