Firstly I'll explain this pc worked fine for 2 years.

Asus tuf z790 D4 motherboard
Corsair 3600 ram in 8GB X4 sticks (new being the same but 32GB X4) both ddr4
Asus tuf 3080ti GPU
2 m.2 drives, 2 hhd, 1 SSD (boot)
Corsair hx850 plat psu
Windows 10
Story
Tldr I need more ram and now it 10/90 on if it boots but it doesn't work
I needed more ram for projects so I got some more
Tried going into bios before replacing the ram just to reset to default settings but for some reason I can't get into bios it would just boot straight to windows
Thought this was strange so I tried going into bios by windows advanced settings, nothing
I took the motherboard battery out and left it for about an hour (this was to try resetting bios to default)
After this I tried just putting in the new ram booted annnnndd
No display
I thought this was odd so I placed the old ram back in and booted trying to get into bios again it went straight to windows
But that's fine maybe I just got a DOA ram stick.
I'll test them in another pc but they worked fine
I went back to my main pc and realised I'm missing 3 drives (all important to me)
I checked every connection just to make sure and pulled out one drive to check if they are working and they are fine
Maybe I didn't seat the ram properly the first time so tried with the new ram just in case no boot but this time my speaker gave me an error code, great!
I have something to work with I thought (long beep 3 short beeps) it's a vga problem
I thought this was odd because the GPU just worked fine and I've never had an issue with it before but let's take it out and check it in the other pc. Worked perfectly
Maybe something gone wrong on my motherboard so I took the battery out and left it unplugged while I went to work (9 hours) came back and plugged everything in checking everything to make sure there's no bad connections and put the battery back in and the GPU and it's boots no error codes, awesome but when the windows login screen comes up the computer suddenly reboots again and then reboots 3 times before not turning back on
I tried turning it back on and I get a ram error code
So I've taken out all but one stick of ram but nothing then tried one stick of my old ram and got it to boot.
But again it turned it's self off
I started to think my PSU was the issue so out it came and back to the other computer (with the GPU just incase) everything worked fine and I tried putting it under load worked perfectly
Now every time my main computer boots most of the time I get nothing displayed
Sometimes the motherboard indicator lights are stuck on boot
Or it turns off randomly
Things I've tried and for what parts
Bios
WIndows advanced settings recovery (didn't boot into bios)
Unplugging everything and taking all drives out (didn't boot into bios)
Taking CMOS battery out (no change)
Leaving the battery out and pc unplugged to dis charge it (including holding down the power button for 20 second no change)
Force flash with usb (no change)
Ram
New sticks (no boot/random boot)
Old sticks (no boot/random boot)
1 of new then one of old (no boot/random boot)
Completely different ram (no boot/random boot)
Tried all sticks in a different pc works perfectly

Changed Rez and refresh rate (no change)
Tried in different pc works fine
Tried a older GPU in my main pc. (No change)

Reseated all connections (nod change)
Tested in second computer, worked perfectly

s there any other troubleshooting I can do that I've missed or is my motherboard or something else dead?
