I have reseated the CPU, reseated and replaced GPU, checked each stick of RAM and a memory check, reset BIOS to default, and tried to do a clean install with a live USB. No luck.
It posts to BIOS no issues. I can usually get it to the grub but as I try to boot the OS it just stops and reboots to BIOS. I either just get the Linux splash screen for a minute or if I boot it in recovery mode it runs script for a bit and boot loops.
It doesn’t give me any errors but finally got it to give me this below. A boot loop is almost always RAM but I am wondering if the CPU is bad

Seems like you have tested most of the stuff what about the hard drive. It works fine if you run from the usb with something like knoppix but not if you run from the drive? Your output doesn’t mean anything to me I just hadn’t heard you say anything about the hard drive. Or verify all was well booting from another source.
I plugged in a live USB. It loads the grub but if I try to load the live version or comparability version it stops during loading and reboots to BIOS
Gotcha, that’s all I got, good luck!
Thank you 🙏. I’ve tried everything I know to do. Compatibility mode should have fixed it if it was a software / driver issue.
All I can come up with is the CPU is bad. Not impossible but that generally doesn’t happen
