Recently purchased MIS Pro z690-A Wi-Fi ddr 4. & I5-12600 alder lake processor.. After assembling build outside of case all worked ok. Now that I have installed in case I get cpu error message on board and will not boot. Only try’s for a short while & shuts down and try’s again. I believe that the cpu may have failed. What are my options in this case? EZ Debug cpu light stays on. No bios posting, no video out. Tried resetting bios to earlier version still no luck.

More Details help>>Posting Guide<<

Take back out of case and check again you may have moved something when putting it in the case Once CPU cooler was on did you remove it to place the motherboard in case.

You may also have a Stand off touch the back of board in wrong place of something making contact with Motherboard and case causing a shot

Alan, I have removed motherboard from case and disconnected all nvme’s as well. I did not remove cpu cooler when it was in case. All standoffs appeared to be correct. After taking out the motherboard I removed cpu cooler to check cpu, found no bent pins that I could see. I reinstalled thermal paste and reinstalled cooler . I downgraded bios as well still having same issue. EZ debug light for cpu still comes on and no video out even to check bios :(. I will try one more thing although I don’t think it will have any effect. I will try my old power supply to see if by some far fetched chance PSU is flakey. Although it was new and the same one that I used to start the system outside motherboard and all worked fine. My feeling is that either something went bad as I was installing it in the case. The biggest problem I had with that was trying to get the I/O shield to seat properly in case, had to try several times before it would set into place. I thought perhaps that in doing so I hit the flash bios button and that removed the bios setup but know I don’t think so.

The EZ Debug "CPU" LED can mean different things, doesn't have to be the CPU itself, it's just the first part of POST that can fail. So even with a PSU problem, it would have the "CPU" LED on.

You have to test step by step what the cause is.

I downgraded bios as well still having same issue.
So you used the Flash BIOS Button obviously? Update again to the newest BIOS, and make sure the procedure actually worked (an LED next to the Flash BIOS Button LED has to be blinking for about five minutes).

Updated to newest version & changed PSU.. Still no boot :(. Will try again to look at cpu to see if I can detect any bent pins. Also sent off a note to intel about issue just to see what they have to say.

If you can , try the cpu on an another motherboard
Maybe you can ask in a computer shop, to seat the cpu on a motherboard, so you can know if the cpu is faulty or not
