Question System reboots when OS loads or tries to install

[Xarkkal]

I've been troubleshooting this for about a month now, and it's driving me insane.

My computer rebooted out of nowhere, and when it came back up, as soon as the windows screen with spinning dots appears, the system reboots. Windows repair starts, and the system reboots.

I figured I needed a fresh install. When I try to install, I can select 64bit, the windows screen with spinning dots appears, and the system reboots.

I tried booting onto a Linux usb. As soon as it starts loading, the system reboots.

I have replaced the PSU, motherboard, GPU, RAM, and tried a brand new ssd. No matter what I do, I cannot install any os or boot into a live usb.

I have literally replaced everything except my processor. I feel like I'm just missing something. This processor is only 4 years old.

I have tried remaking windows 10 iso usb in Rufus and the tool, same results.

Please help!!!!

128g ddr4 and 64g ddr4 - these were both bought as kits (128g ddr4 kit and 64g ddr4 kit)?

850w and 1000w psu - when you changed the PSU, you changed the cabling?

Yes, two separate kits. The Ripjaws 4x32 I was running for almost 4 years. The 2x32 Corsair I just bought and tried today.

Yes, all cabling was changed when I changed out the PSU.

You've replaced the coin cell battery?

You've replaced the coin cell battery?

CMOS was replaced on the x570 Taichi. I have not replaced the CMOS on the ROG Strix because it's a brand new MB.

Okay, but it's cheap to do and how long was that board sitting on a shelf new before you bought it? (x570 boards started coming out in 2019, B550 2020 I think.)

Are you using a new usb? Have you checked it in a PC known to work well.

I'll try a brand new cmos in the B550
Flash drive is new. I haven't done a full install on another working PC with it, as I don't have one to test it with.

I changed the cmos, problem still exists. I have redownloaded and recreated the iso file, and tried Linux usb multiple times. I don't have another PC that I can image to test the usb on.
