Maximus Z690 Hero won't post; stuck on Q-Code 00

The fans spin up briefly and that's it. No signal going to the monitor; Q-Code is stuck at 00. Q-LEDs are off. Unplugged everything from the motherboard except the power cables; same thing. Was able to do a BIOS flashback; no help. Any ideas?

Any chance overtighten cooling solution (cpu heatsink), back it off 1/4 turn on the screws.

Hello,

As above,

Check motherboard stand off screws aren't over-torqued

Reseat CPU whilst checking for any bent pins, then remount cooler whilst ensuring even mounting pressure

If no joy, remove the motherboard from the chassis and retest

Using Corsair 150i Pro RGB with the proper stand off screws. Did it anyway and reapplied thermal compound; no joy. So you guys think it is CPU related? I was using the same CPU and RAM with another motherboard( Asus Prime Z690-P) and it was working fine. Updated the BIOS and decided to try the XMP-2 settings on the mobo and the system died; reset bios, etc. nothing helped. Now I am getting the same problem with the new mobo; CPU KIA? i7-12700K.

Given what you're saying above, it sounds like the CPU needs to be RMA'd, yes.
