Ideas on what could be wrong.

[Rubiqcube]

Hi forum, just looking for ideas as to what may have caused this issue I’m facing. 
 

PC was working fine yesterday, and at some point last night it crashed and became unresponsive.

 

Here are the symptoms. PC won’t post at all - can’t get any display from either GPU or iGPU - no RGB lights on anything except the GPU (this is just the Aquarius branding that lights up). Still getting fans spinning on CPU and case fans, and external USBs are still being powered (aside from mouse and keyboard which are not). Power button does not work once powered, can not reset nor turn off PC.

 

Here’s what I’ve tried.

 

Removed GPU to try and post from iGPU.

Reset CMOS.

Tried different ram sticks, note both ram sticks have RGB on them - however, the main ram doesn’t light up but the secondary did. 

Is this likely a mobo just failing or a power supply? I know it’s difficult to say but I can’t see the PSU just randomly failing. But the mobo is less than a year old. 
 

Specs:
 

Ryzen 7700x 

Gigabyte B650M Gaming Plus WiFi AM5 mATX

Kingston 64GB (2x32GB) KF560C36BWEAK2-64 Fury Beast RGB 6000MT/s DIMM DDR5 RAM

Corsair 750W RM750 80+ Gold Fully Modular ATX

There should be debug LEDs labeled CPU, DRAM, VGA and BOOT (or similar). Does any LED stay lit up? That should indicate where the fault lies

Welcome to the forums!
I actually can't see anywhere on that board or in its manual which talks about debug LEDs. There is a Speaker header next to the front panel connectors which says that it's used for beep codes, but there is no indication of what any of those are except a single beep for correct POST. 
Are you certain the monitor and cable are good?

Nah, these no debug lights. Yeah, certain the cables and the monitors and cables are good. The only thing I can think of is there was a short or something last night that cooked the mobo, but it’s just all very odd. All the components are in a return to base warranty period at the moment, so I’ll probably just dump the pc off and see what they say.

Oh, so this is a new build? Can you try running only one stick at a time? Make sure to use the A2 slot for testing the RAM

Nah, not a new build. Been going solid for about six months.

It is WILD that this mobo doesn't have debug LEDs and also doesn't come with a beep speaker. If you have a spare one, or are willing to buy one, you could actually figure out what the mobo is upset about. I wonder if you can contact GB and see if they'll send you one...
However, it could still easily be the RAM, do test one stick at a time in A2, and of course wait for memory training (this can sometimes take 10 minutes)
After that, we kinda need to test each component
