    PC Boot issue

    Relevant Specs:

    MOBO: Asus ROG Maximus XII Hero (WI-FI)
    Cooling: NZXT Kraken Z73 360MM
    CPU: Intel I9 10850k
    RAM: Corsair Vengeance LPX DDR4 3200Mhz (2 x 8GB)
    PSU: Honestly, can’t remember the brand, but it’s 1000W
    GPU: Asus ROG Strix GeForce RTX 3060 V2 OC Edition
    NVMe/Boot Drive: WD Blue SN550 2TB
    OS: Windows 11 Pro

    It all started with what should have been a simple RAM upgrade installation. To be clear, my PC worked just fine before I started this process, booted almost instantly never had any issues. I removed the Corsair, and replaced it with 4 x 8GB sticks of the G.Skill Trident Z RGB 3600MHz. It took three tries to get the PC to boot after installing. Finally it boots and Windows loaded up, checked to make sure it was reading the RAM properly, it was. So I restart and try to go into the BIOS to adjust the RAM speeds. It just would not allow me to enter the BIOS menu for some reason, after about 15 failed tries and multiple troubleshooting methods, I take my PC apart, reseat everything, and remove the CMOS battery for an extended period of time. I turn the PC back on and finally get into the BIOS. After adjusting the RAM speeds to 3600MHz in the BIOS and saving, the pc restarts as expected and the mobo goes through multiple checks and eventually lands on the A2 error (IDE Detect, essentially a boot drive error). My boot drive was working just fine prior to changing my RAM Speed to 3600MHz in BIOS. So I shut down, remove the CMOS battery again and swap the old RAM back in to see if it will at least boot just in case the new RAM was the issue. It still throws the A2 error, I cannot even get back to the BIOS menu even after resetting the CMOS battery, my monitor just stays idle and the PC doesn’t post. I did also try removing the NVMe and reseating it after I got the error. I’ve tried everything I can think of along with whatever I could find on google with the tools that I have at my disposal.

    Any insight as to what could actually be wrong or some solutions I can try would be greatly appreciated, I’m beyond frustrated and I’m not sure what else to do at this point.

    I know you have removed the battery for cmos.
    What happens if you use the CMOS reset button on the back of the board
    Top left hand above the bios flashback button (do not press the flash back button)
    Why are you trying to push your cpu so far

      When you removed the CMOS batter did you also long press the power button to discharge any residual power?
      Usually a user needs to turn off the pc & remove the power cord, remove all devices, remove the battery (if a laptop), remove the CMOS battery, log press for 30 seconds on the power button then leave it for 30 minutes.
      Once complete reinsert the CMOS battery, laptop battery, power cord & all previously connected devices & turn on PC.
      Did you earth yourself before opening the PC? If not & you touched the HD then static may have damaged it.

        Yes, I did remove all peripherals and drain the mobo by holding the power button for several seconds. I did also try using the reset button on the board. Still getting the A2 error on the mobo. The m2 drive is covered by a plate, at no point in the process did I touch it until the end when I decided to try reseating it, so it was already giving me the A2 error before I ever touched the drive. I was careful to ground myself before touching anything as well. I’d say I left the CMOS battery out for at least an hour before putting everything back together and giving it another try.

          So still no bios ?
          What monitor do you have 4K
          If yes do you have an older monitor that is not 4K
          Try that

          Are you earthing yourself with a wristband?

          Have you tried the retry button

          Have you tried putting the M2 into another M2 slot

            Is it possible that the “IDE Detect, essentially a boot drive error” message indicates that the system has reverted itself the HDD access mode to IDE (instead of AHCI or RAID)?
            This may be the result of the system been disconnected from the power source-due to the memory being replaced.
