Hey guys, I'm upgrading my current PC to the latest 13th-gen 13700kf. Currently, the motherboard MSI PRO Z690-A has CPU red light on and is in an infinite boot loop. While waiting for the replacement motherboard to come, and I still have the motherboard with me, I'm thinking of what else could have gone wrong.

The BIOS was flashed to the latest version, and it should support 13th Gen CPU.
I've sold my old 12th gen CPU. Unfortunately, I wouldn't be able to test it with a working CPU on the Z690 motherboard(silly, I know it).
I've tested my RAM, PSU and Graphics card and can confirm they work on my 9th gen Intel platform.

Here are the things I've tried:
Remove RAM and test one by one
Reinstall CPU
Remove all power cables and plug in again.
Flash Bios again using USB and remove all components (PC booted up without any issue after the first flash and never booted on subsequent runs)
BIOS versions tried are7D25v18 and 7D25v192
I tried flashing it a few times but found the BIOS flash LED only blinked red once and never lit up again.
Reset CMOS by removing the battery and jumping.

None of these solutions works; it is still in the boot loop with CPU red light. The red light is not blinking, it just stayed on.

Would there be anything else I could try?

Result: Bent pins. Did a warranty claim and the new motherboard works perfectly.

    Did you try the PSU from your 9th gen rig?

    • ty99234 on 26/10/2022 - 15:39

      Yes, it works.

    I'm assuming everything else is existing, and you're just replacing the old CPU with the 13700K.

    Did you update the BIOS to the latest or at least a version supporting 13th gen before selling off your old one? Would've been ideal.

    If you're able to flash the BIOS again, perhaps try a different version that can still support it.

    Otherwise it's gotta be a BIOS issue, or a faulty motherboard - seems like it's a common issue with this board.

      Yes, I have. The weird thing is that the PC booted after my second bios flash but wouldn't boot in subsequent runs.

        Yeah, that's trippy. I'd personally just wait for the new motherboard to come in and save myself from a headache.

        Good luck, mate.

    Which BIOS version did you flash? And are you using DDR4 or DDR5?

    • ty99234 on 26/10/2022 - 15:44

      7D25v18 and 7D25v192

        Even though that should be fine, I'd have a go at flashing 7D25v17, since that's the one listed in the compatibility section (https://www.msi.com/Motherboard/PRO-Z690-A-DDR4/support#cpu). I don't think it's likely the issue though, but it'll only take a few minutes, especially if you don't bother unplugging all the components (although I'd probably unplug the GPU so you don't have to listen to the fans).

    What Causes Red Light on Motherboard Problem?
    Damaged hardware- If any of your hardware is damaged or corrupted then you may encounter this red-light issue. Hereby, check for the faulty hardware and try fixing the problem by repairing or replacing the affected hardware.
    Lose or broken power supply cable- Another reason triggering such an issue on your Motherboard is a loose power supply cable connection or damaged cable. So, if found the power cable to be the culprit behind this problem then try dealing with the situation by replacing the damaged cable or plugging it properly in case of a loose connection.
    Misplaced GPU or CPU- Sometimes, your misplaced GPU or CPU may trigger red light issue on Motherboard. Therefore, when such a scenario appears, check if the CPU/GPU is placed properly on the Motherboard. In case found improperly placed, try tackling the situation by placing it back properly in its place.
    Overheated CPU- At most times, running your system for a long time may overheat your CPU which can further result in showing the red light issue on your Motherboard. Therefore, such a situation can be handled by cooling down your CPU or system by substituting the hot air with the cool air.
    Drained CMOS battery- If the CMOS battery you are using is drained out completely or gets dead then you may get into this problem. So, when such is the reason behind your problem case, try treating the issue by replacing your CMOS battery with a new one.
    Damaged or Misplaced RAM- Another possible reason causing this issue to occur is damaged or misplaced RAM. If the RAM is not properly seated or is damaged then you may face this red-light issue. Hereby, check for the RAM. If found misplaced, reseat it properly to fix the problem. In case damaged, try replacing the RAM with a new one.
    The issue with the hard drive- In most cases, an issue with your hard disk may drive you into such problems. So, when such is the cause found behind your problem scenario, try dealing with the issue by replacing your hard drive.
    BIOS issue- An issue with the BIOS can also cause the red light to appear on the Motherboard. If the BIOS is wrongly configured then it can trouble you with this problem. Therefore, when found fault in BIOS, try resetting it correctly to get rid of the issue.
    Faulty Motherboard- If the Motherboard itself is at fault, then also you may encounter a problem with the motherboard. In such a case, you need to replace the faulty Motherboard with a new one to fix the problem.

    With so many CPU inserts / removes, I am guessing bent motherboard pins :/

    • ty99234 on 03/11/2022 - 16:48

      Sorry about the late reply. You are absolutely correct! There were a couple of bent pins, so I made a warranty claim.
      I got the replacement motherboard a few days later, and it worked perfectly.
