  • A second idea if you cannot source another gpu; Change PCIe slots. While I believe your video card is going bad or at a minimum: overheating: consider moving it to the other x16 slot on your mobo as it IS technically possible the slot is having issues. It also doesn’t hurt to spray your case out with canned air to get the heat capturing dust out.


  • While I call it init, many will assume I am referring to the boot init, but I am actually referring to the bios initialization (init).

    That said, most BIOS inits go in this order:

    • Power Detection check. If enough power, proceed.

    • CPU program link, CPU calls the BIOS to basically wake up and run the bios program.

    • Ram Detection check. If RAM is present, the BIOS will use about 64k to load from ROM to RAM (called the bios reserve area) that then does the next steps.

    • Hardware Detection check. Identifiers of the hardware are detected, enumerated, configured and initialized.

    • Boot Sequence is initialized whereby the BIOS does a handoff to the bootloader.

    It’s during the hardware detection phase when the display is initialized by the gpu and you often see it displaying the bios version, then counting RAM. If the gpu is working BUT the display out isn’t, it’ll actually continue to boot 100% of the time (it doesn’t care). If the gpu hardware itself doesn’t respond correctly to the BIOS request however, it sends the hardware detection of the BIOS into a loop or shuts the system down, never getting to the final step: boot sequence.

    Depending on the bios type, it may or may not show numlock. I’ve also seen it act differently on UEFI enabled systems than when it’s set to classic bios. So, it just depends.

    Regardless, see if you can source another pcie gpu for testing this. It only takes a minute and tbh, it doesn’t hurt to have a cheap used pcie vid card in your pc tools for such things.

    Good luck!


  • I agree with Brkdncr, this sounds like a video card issue.

    I’ve had this problem multiple times before. The combination of display glitches and the fans spinning but no numlock or keyboard functionality simply points to the video card first.

    In short, during POST of the BIOS it attempts an init to the display, fails and then stops attempting the boot sequence. It, the video card, is just as important during init as the motherboard registers, RAM and CPU all starting.

    So, start with video, see if it works without the 5700XT and using the onboard or some other cheap pcie card. If that fails too, then it’s most likely the mobo as assumed. This just doesn’t sound like a mobo issue though.
