Question Why does my display and peripherals turn off after boot?

[Hollow377]

So recently I've decided to upgrade my GPU and CPU, and I updated my BIOS as well to make my new CPU work with it. I got the GPU first, switched out my old one and started using it, everything works perfectly for a few days. I also updated my BIOS, everything was good. Then I got my CPU. I installed it, got to the "new cpu installed" screen and hit Y on the fTPM screen because I don't use anything like BitLocker to my knowledge. PC boots up fine or so it seems, after 30sec-2mins the display and peripherals go, I noticed this because the RGB went out and the GPU fans stopped spinning. CPU fan and 3 case fans still working though, and I can't seem to turn off the power by holding the power button. PC works fine in BIOS or in Safe Mode, which I can't get into anymore because I decided to reinstall Windows which was the last thing I did today. Things I've tried:
- I thought the PSU was at fault as it was an off brand (maybe off brand - Cronus 500FX Pro something) and thought it didn't give components enough juice. Today I switched it with an A tier one 800W (overkill you'll soon find out) and it still does the same thing, all cables are properly seated and everything went well with the installation (only good thing to happen so far lmao)
- reinstalled the same BIOS update (F58d) thinking it's gonna somehow fix it
- went into safemode to uninstall GPU drivers with DDU, tried installing them again IN SAFE MODE due to not being able to hold out 30 seconds in normal mode, and this made it so that the gpu and peripherals now instantly shut off instead of waiting a bit, nice

I also think it's worth mentioning that safe mode worked perfectly and this only happened after unlocking the screen in normal mode, but now it doesn't even wait for the screen to be unlocked
+ When I updates BIOS before installing CPU I also updated chipset drivers in the gigabyte software tool thing
+ I uninstalled my old GPU drivers before installing the new GPU and it worked fine, this happened after installing CPU and going thru the ftpm process and booting first time
+ There is a regular red blip sometimes next to the power button from one of the LED lights but it turns off after all goes down

I am pretty sure it's not the GPU as it worked perfectly fine before and peripherals go as well when this happens, but I will try switching out to my older one GTX1650 tomorrow if y'all think it's a good idea
My specs:
Ryzen 5 5600 (old one was Ryzen 3 3100)
RX6600 XT (old one was GTX 1650)
2x8GB RAM ADATA XPG
1xnvmE SSD Crucial 1TB
(I had a Seagate HDD that I removed because it's either having that or having the new PSU that's a bit oversized for my case)
and I guess the most important (the main suspect??!!) Gigabyte GA320M-H motherboard(rev.1)
Also the 3 case fans with fan splitter and stock amd wraith cpu cooler if that counts for anything

Only thing I can think of right now is driver or BIOS issues I dunno how to solve, or something wrong with the CPU or Motherboard
How cooked am I on a scale of 1 to 10? I just can't figure out what the problem is

First let's start simple
CMOS reset, take the battery out for 15 secs,
Reseat the ram,

Hello. I will try taking out the RAM tomorrow, speaking of CMOS reset, I actually just ordered a CMOS battery because I didn't have one (bought pc prebuilt). My question is, should I install the battery and perform a reset after or should I just use the CMOS jumper? I could do the 2nd one but 1st one seems a bit more easy as I've never done it before? What's your recommendation?
Also should I do these in the order you said them in? Like take out CMOS, THEN reseat both RAM, then put CMOS back and turn PC on? Thanks so much

Yes, do the first one, just take out your existing battery, no need for a new one. And yes do it in the steps I have mentioned.

If u still face issues, go to bios, disable tpm and secure boot, disable CSM, disable xmp/DOCP.

Will do and will reply to you afterwards, sorry I might've explained bad, I don't have a CMOS battery right now as it's missing, I don't know why as I bought the pc pre-built and never noticed it but now I bought some and will put them in and try your steps afterwards hopefully. Thanks

Also disable secure boot.
