Hi my new pc.

12900K with NZXT KRAKEN X73

2x16GB DDR4 KINGSTON DDR4 3600

RTX 3090 Ti Gigabyte

Aorus Z690 Elite DDR4

SEASONIC 1300 PX PRIME PLATINUM

whenever i turn it on all the leds and fans turn on for a half second then turn back off again, repeat. I cleared CMOS battery. Unplugged GPU. Removed 1 stick memory the same. So what now? What part are bad? Also reseated cpu and still nothing.

My friend come with hes mobo Z690 and all parts working fine with hes mobo. So i went to shop and they exchanged me Aorus Elite Z690 to other example. I will report later.

All working fine with new motherboard. And insane low temps on 12900K. GREAT. But had weird stuttering in Far Cry 6 benchmark but now working all fine.

Is this possible that first motherboard was faulty? Shop exchanged me to other example and it booted fine , when first motherboard was shutting off during start.

Yes, it's possible. Does it matter? No. The shop gave you a new one that does work, so what was or wasn't wrong with the first one is immaterial.

I wonder how he manages to afford all this super expensive equipment. He's like a Pierson's Puppeteer constantly rolling into a tight ball from anxiety.

are you actually building these new systems?...maybe get someone else to build it for you
That might actually be the best for him. Someone that is good at building and tuning a pc to just build it for him and then he can actually game instead of making threads that would best be answered with "turn it off and back on again".

Hey, let the poor guy do whatever he likes. Ignoring his threads requires literal zero effort.
It's not like he argues with knowledgable people and calls them stupid like the guy who microwaved his GPU.
