PC randomly shuts off & won't start up for at least an hour + Doesn't turn back on when restarting

Hi there, I've tried a few different things to fix this. Below is my event viewer log.

My system and hardware:

Windows 10 (My PC is able to run Windows 11, but I prefer Windows 10)

Corsair RM1000x (2021) 1000 W 80+ Gold Certified Fully Modular ATX PSU

Intel Core i9-13900K 3 GHz 24-Core Processor

MSI MPG Z790 CARBON WIFI ATX LGA1700 Motherboard

MSI SUPRIM X GeForce RTX 4090 24gb GPU

G.Skill Trident Z5 RGB Series (Intel XMP) 64GB (2 x 32GB)

The problem:

My PC shuts off without warning and won't turn back on afterward

When I try to restart my system, it boots down normally, but does not start back up

What I've tried:

1- After the shut off and failed attempts to turn my PC on using the power button, I flip the psu switch to the OFF position, then unplug the psu cable.

1a- From here I've tried plugging in the cable + flipping the switch, and turning on the PC. Any sooner than ~1 hr, and the PC won't turn on still

1b- Hold down the power button on my PC tower for 30 seconds, plugged in the cable + flipped the switch, pressed the power button again, nothing

2- Tested the outlet (a surge protector power strip) that the PSU is plugged into - work's perfectly fine. Also, to note, the total power draw from the power strip doesn't exceed it's max load

3- Tried plugging the PSU into different outlets

4- Unplugged and re-plugged every pc part inside my tower from the PSU

4a- PC still didnt boot up

4b- Afterwards, I removed the GPU, memory sticks, and basically dissembled the PC in order to air dust as thoroughly as I could.

5- Removed two of my SATA 2.5 SSDs (Crucial MX500) that were giving me problems (around the time this started happening, I remember that these two were not showing up in device manager/diskpart)

5a- at first, only one sata ssd was causing issues. I assumed that it probably failed- and read that a failed disk could cause boot up issues. So I took it out of my tower + the sata cable to the motherboard & PSU

5b- I turned it back on after like an hour, and it worked, but then my other SATA ssd was not showing up suddenly. Now these are both removed from my PC tower. I never reinstalled them.

Notes:

• I don't THINK I'm overclocking anything (I'm not the most informed when it comes to the technicalities)
• The only tweaking I've done in the BIOS is my memory settings
• I set the default settings to the actual speed it's meant to run at (6400 MHz)
• My drivers are up to date. It's possible I could have missed something
• I have hit the BSOD a few times with the following code
• DRIVER_POWER_STATE_FAILURE

Please feel free to ask any questions. Just an FYI, I haven't tried booting up my PC since it last shut down on me only because when I turn it on, it'll either shut off on me, or I'll put it to sleep/turn it off myself, and it'll be another cycle where I can't turn it back on again after for a few hours.

If there is any info you'd like me to provide (dumps, logs, etc.) LMK and I'll boot my PC up and try my best to gather the info as needed.

EDIT:

• Totally forgot to add the fact that my motherboard has a "LED hexadecimal debug + EZ debug LED indicators" - here were my collective results (sometimes, only the hexadecimal codes appeared)
• E0
• 4F
• A2 + White LED

Thank you so much!
