Computer stopped working and now powers itself on and off rapidly

I just built a new computer and it had been working for a few days. Now whenever I try to start it it just keeps turning itself on and off every few seconds. It never stays on long enough to get to bios so I can’t check that, but all the fans work and the motherboard lights up, but the ram stays unlight. My motherboard the Asus 299x-e gaming gives me a q code of 00 but the book is vague about what that means. I have tried resetting the ram and using the CMOS jumper but it has not fixed it.

If you can find friend who also have X299 board then try install your CPU to it,

CPU
Check HSF, or maybe redo TIM + no broken pin + redo HSF seating.

PSU
Are all connector work? try use other PSU.

00 is CPU not installed or incorrect version, since its been working for few days then I suspect its motherboard or PSU
