Motherboard - White VGA light remain ON

[Pyception]

Hi All,

Need your help here. I had a power outage here earlier today and now my pc is not booting.
I've noticed constant white light (VGA) in Motherboard and display is not showing boot menu. Motherboard is Asus x570 TUF Gaming Plus.

I looked up online for help and already tried below steps.

Removed and reconnect HDMI/DP cable
Removed RAM and reinserted after cleaning contact point
Run with 1/2/4 RAM sets
Removed GPU and reinserted after cleaning contact point
Clearn RTC by contacting both pin (Didn't removed CMOS battery for now)

What else can be done to solved my problem.

Sounds like a classic case where there may have been a surge of power to the GPU.

What is your CPU and PSU?

Do try the CMOS battery. Also, have you tried different HDMI port(s), if your card has more than one?

Below is the specification-
CPU- AMD 5600x
PSU - ASUS ROG-STRIX-750G
Motherboard - ASUS x570 TUF Gaming plus
GPU - MSI Ventus 3x 3080
RAM - Kingston Fury 8GB * 4

When the power button is pressed, the fans spin and RGB lights up as it should. No display is outputted, via DP (Display Port) or HDMI. I've tried different display port plus HDMI port as well.

Have you checked the PCIe connectors for any burn marks? Try reseating the CPU (stranger things have happened). Have you tried inserting the GPU into the 2nd PCIEe slot?

My advice: pick up a cheap display card like a GT 210/610 for <1000 and rule out your 3080 as a potential culprit

PCIe connectors looks fine. Removing cmos battery didn't help either.
After doing above process something happend. One time I was testing with 2 RAM, I got the green (boot) light after white one. But nothing came in monitor.

Try disassembling draining power from all components. Wait for a while and reassemble. Try single stick of ram in seperate slots. Also check if caps lock and num lock are functional. If they that means system is booting just isnt displaying

Are you running the system without UPS?

Green led remains on (it should off after few seconds), still didn't get the output in monitor. Yes, right now it's without PSU. I've shifted pc last week in bedroom due to winter. Big mistake

Keyboard is getting light, caps/num locks working.

Sounds like a GPU issue, because the system seems to be posting. I suggest going with what I had advised.

Finally, got the ouput in monitor. Tested few times after that by shutdown/restart and seems no issue so far.
Thank you all for your expertises .
Next question is how do I test my cpu/psu/gpu apart from physical clues.
Should I run any benchmark/stress test?
