Hi,
My PC started having problems boot looping, so in this order I did:
1. Pull out 1/2/3/4 RAM modules and lastly introduce a new, tested module from another PC
2. Reseat the CPU and replug the Graphics Card
3. Clear CMOS
4. Replug all cables inside and outside the PC
5. Unplug all exterior cables besides power
6. Use a different power outlet, use a different power cable
7. Extract the MB and screw it back in confirming all standoffs etc are correctly placed and nothing can possibly cause a short circuit
After none of this helped even reach BIOS or POST at all (no beep), I went over to a friend and:
8. Put my GPU into his PC to test (worked)
9. Put his old GPU
which doesn't require external power
into my PC (worked) (its a very small, old, i think AMD card which doesn't even have a fan)
Then I checked my PSU manufacture date and found out it was 2018-03, so roughly 13k hours of uptime, probably time for a new one.
Bought a new one, it worked for a few days and now the problem is back. (When changing the PSU I also removed the MB and reinserted it into the case)
First instance was it boot looped a few times then came on, right now the loop is endless.
I do not have integrated graphics. I have an old GPU which also requires external power. I can try and borrow my friend's old (non externally powered) GPU to test with.
The bootloop happens before POST beep, and I assume it's that it's trying to power on the GPU and fails, but I might be wrong, I heard that it needs to do some negotiation and might fail to find values if e.g. CMOS battery is weak?
I am going to buy a new CR2032 battery for the CMOS today and hope it's that. If not probably going to try and see if maybe it's the GPU's fault (doubt, it worked in the friend's PC and is fairly new), or RMA the new PSU. Have a multimeter, what else can I check or do?
Thank you.

I verified the PSU's manufacture date and discovered it was from March 2018, indicating around 13,000 hours of operation—likely time to replace it.
Purchased a replacement, it functioned briefly before the issue resurfaced. While changing the PSU, I also removed the motherboard and reinserted the new one.

GPU:
Zotac GeForce RTX 3080 Fan X3 12G Gaming LHR
The RTX 3000 line was known for significant transient power demands. It was recommended to overprovision wattage when selecting a PSU, in addition to choosing a stable unit. A 1KW model is suggested;

RAM:
Goodram IRDM X (2x16GB at 3200MHz + 2x4GB at 2666MHz) – all RAM clocks are set to 2666
It’s recommended to use pre-assembled kits rather than mixing RAM modules to ensure the total capacity is correct.

Could it be that the sudden load spikes only became noticeable and triggered loops after more than a year of operation? (I don’t recall the purchase date of the GPU, but it’s definitely not brand new, and it’s been used consistently for over a year without any problems, with the 750W PSU.) The RAM has never caused any issues either—it’s not a recent build. The only part that changed recently is the PSU, which has been in use for about six months. I tested it with just one RAM stick, and there was no improvement. If the PSU fails, I could attempt a refund and obtain a 1kW replacement unit.
