Week Old Computer Stuck in Boot Loop with Occasional Boot Success. Poss RAM?

I built a computer for my brother about a week ago and the first week it booted up fine.
Recently it's became tempremental in booting up, 1 out of 20 times is successful, the rest it gets stuck in a boot loop. It's only sometime successful when hard resetting (unplugging as well) or visiting the BIOS.

All drivers are up to date, checked for hard disk failures/issues, cleared the CMOS and defaulted BIOS settings/BIOS is up to date.

There's a EZ Debugger on the motherboard which when boots LEDs cycles through CPU, DRAM, VGA and then BOOT. At the moment, the only LED light that skips is the DRAM. During the loading (smaller circles circling in and out of view) it freezes after about 3 cycles and then boots into the blue screen automatic repair. Before it would successfully cycle these 4 LEDs and boot into windows no problem, albeit after the first few days would take twice as long (10-15 seconds).

I've removed the RAM sticks, and booted it up cycling 1 RAM stick in each of the 2 slots. I did this with both and it still does the same thing. Skips DRAM LED and boot loops. I booted it up without the sticks and the computer doesn't boot up, but the DRAM LED lights up and stays there, which is what's supposed to happen, signalling there's no DRAM detected.

The BIOS shows the RAM sticks installed as well as brand and speed so it detects them. When the computer boots successfully, it cycles all 4 LEDs and there's no issues from the RAM when the computer boots successfully.
  • MSI B450M PRO-M2 MAX Motherboard
  • Team Group Dark T-Force 16GB (2x8GB) DDR4 PC4-25600C16 3200MHz.
The Motherboard supports base RAM speeds up to 2400MHZ, which the RAM seems to be happy running at, up to 3466MHz overclocked (not yet ran it at higher speeds). Unsure whether this may be a problem that could cause this, or if the RAM sticks are faulty, or if the motherboards DIMM slots are faulty... or something totally different...

EDIT: Ran memtest86 for 4 runs (around 3 hours) and no errors popped up. Also unplugged all components I could (If CPU/VGA/RAM the motherboard doesn't go to boot so can't test them). Still froze on boot so plugged them all back in (and replugged all power connections just in case one was loose) and still the problem persists. Will order some motherboard compatible RAM to see if this solves it.

To ensure it's not OS/software, which minus the DRAM LED skipping I'm thinking it may be. So just going through some of the automatic repair options, repair re-install or worst case a total clean reinstall of windows.

EDIT 2: New RAM made no difference, still boot looping so did a clean reinstall with windows and the computer works fine until I install Adrenaline/drivers for the GPU. Made a new topic as this is no longer relevent https://forums.overclockers.co.uk/t...s-with-adrenaline-causes-boot-loops.18893032/

Too much text to read all, if you don't have spare parts it's a bit of a mare to figure out... Try it out of the case on cardboard, try 1 ram stick, try with everything discon as possible (inc power sw/reset/hdd light etc.. Different gfx if possible and different psu

Sorry edited it down. Was trying to get as much info of what I tried to troubleshooting but I ramble.
I've unplugged a few components but the computer doesn't boot when certain components are unplugged, the EZ debugger doesn't boot until it detects CPU/RAM/GPU so wouldn't know if that solves the bottom. I will try it everything else though.
Don't have spare parts unfortunately nor do I really have the funds atm to buy a bunch of parts to test but as the motherboard is suggesting it may be something to do with RAM was just going to buy and try another stick of ram in there. Already tried with 1 ram stick, interchanging both the slot and the stick of ram.
