New graphics card impossible to get working

Solved

Hello everyone,

I upgraded my old clunker to keep up, and I currently have this setup:

- AMD Ryzen 7 5800X
- Alaska 850W power supply
- B550 Gaming Plus motherboard
- 32 GB RAM
- MSI 1TB SSD
- An old MSI R9 270X GPU

I bought a new graphics card to move to an ASRock RX 7600XT 16GB but I can’t get it to work. It powers on, fans spin and LEDs light up, but there’s no output signal as if my motherboard doesn’t recognize it, so no display on the screen. I put the old one back and it works.

I changed HDMI and DisplayPort cables, swapped the PCIe power cable between the GPU and the PSU, updated the BIOS, updated my PC drivers, tried on another monitor, but nothing. I don’t know what else to do...

I can’t install the new drivers for the new GPU because the AMD software detects my old graphics card and tells me it’s not compatible, but with the new one my PC doesn’t recognize it, so I’m not any further...

Have you ever had a problem like this? I’m completely lost here...

Thanks in advance for your help

    Hi

    There aren’t many possible causes with a newly assembled hardware:

    1. We forget a power connector (there are at least two 8-pin sockets on the 7600XT, you need both, it’s mandatory)
    2. It is inserted poorly, for large GPUs you should not hesitate to press firmly so it fits completely into the slot.
    3. It’s dead on arrival, rare but concerns a few percent of sales (the best before concluding is to try it in another PC)

    Hello,

    Windows + R
    Type -> devmgmt.msc and OK.

    Do you have a section -> other devices?
    If yes, which device is problematic?

    What do you have in Display adapters?

     no display

    Maybe a check in the BIOS?

    I am indeed on PCIe for the graphics slot

    So still no display when you connect the cable to the new card?
    Still not recognized in the Device Manager?

    If not, any ideas about this problem!

    Wait for other BIOS opinions???

    We are dealing with a recent motherboard, I doubt the BIOS is to blame, at least not for launching a basic display.

    We stay with the 3 hypotheses given in 1; for me, it’s one of the three.

    Wait for other responses; I’m warning about the trolls....

    Seeing a motherboard with a B550 chipset, I swept through possible BIOS causes, but Kaneagle makes me think of one thing anyway:

    What version of Windows are you on? 10? because if so, your BIOS might not be in UEFI mode? The 7600XT might not work in legacy mode; the BIOS needs to be in UEFI.

      No, I’m on Windows 11 Pro. However, I haven’t checked my BIOS in UEFI mode; I’ll go take a look at that right away

      With Windows 11, if the installation was done without tinkering, it is necessarily UEFI

      I have indeed installed Windows 11 Pro with an official key, but my PC is effectively in CMS mode and I cannot switch it to UEFI.

      I get this message every time:

      There is not graphics output protocol support detected in this card.

      BIOS CMS/UEFI mode setting in BIOS will be changed to CMS.

      I don’t know what else to do... is there a mode to force it, is it my old GPU that blocks the change??

      Well, we may have found something........

      We should still try it on another PC with Windows 11.

      I did install Windows 11 Pro with an official key, but my PC is indeed in CMS mode and I can’t switch it to UEFI

      The key isn’t the issue, but the way Windows was installed. Before the release of Windows 11, BIOSs were defaulted to Legacy or CSM, without TPM, and without Secure Boot, so not in UEFI. Since the release of Windows 11, motherboard manufacturers have updated their BIOS and set by default the Windows 11 requirements: UEFI/TPM and Secure Boot, system disk must be GPT.

      Your case is most likely a consequence of that; however, a clean installation of Windows would have aborted at the initial setup, so perhaps you started from Windows 10 and then upgraded to Windows 11; or you followed one of the many tricks to install Windows 11 in legacy mode (primarily without TPM).

      Not necessarily, you have to convert your system disk to GPT (it must be in MBR) with MBR2GPT, then switch the BIOS to UEFI and enable TPM 2.0, except that then you will need to install the 7600XT to get display.......

      In short, you can still run another test: set your BIOS to UEFI, the R9 270 will no longer work, install the 7600XT and you will have control of the BIOS, and you can reinstall Windows cleanly. But if the 7600XT card really has a problem, you will no longer have control of the PC, you will need to do a clear CMOS to disengage UEFI.........I know it’s complicated.......

    Even if it becomes gibberish here, lol, I still did the command prompt invite to check and my SSD is indeed GPT, my second storage drive is MBR.

    The problem is that I can't switch it to UEFI, I get that famous error message and it restarts in CMS. I did write BIOS version in CMS.

    And since when I install the new GPU I have no display because it's probably not recognized, I can't go into the BIOS to modify it with the new one.

    It's complicated, yes ????????

      If your "C" drive is GPT that's already good.

      The error message is to signal that the graphics card is no longer compatible in UEFI because it's too old.............and your 7600 is probably not compatible in CSM because it's too recent.............the scenario is grandiose........

      Do you know anyone who would have a graphics card a bit less recent and capable of operating in both modes? like a GTX1660 for example, or perhaps an RX 570?

        Yes, as you say, it only happens to me this kind of thing, finally I would have built my PC with a new graphics card I wouldn't have had any trouble.

        I’m meeting a colleague tonight to try my new graphics card and, at worst, I’ll try to install his to see if I can switch modes in the BIOS.

        I hope it’s one of these two issues, then. I’ll give you a feedback.

        But anyway thank you for your precious help!

        Hello Flo88, I managed to get help from a colleague and I installed their graphics card (which is 4 years old). I was able to set my BIOS to UEFI mode because it was CMS/UEFI compatible, reinstalled my new graphics card, and everything works like a charm. So it was indeed a BIOS setting issue caused by my old GPU; it was automatically detected and drivers updated without any problem. A big thank you to you for all your information and for helping me resolve my issue.

        Ah indeed, some good news! Thanks also to @kaneagle StatusModerator who reminded me of this possibility of a BIOS issue, it wasn't my initial idea.

        Best wishes with your new graphics card ;-)

        "I was able to switch my BIOS to UEFI mode because it was compatible with CMS/UEFI"

        CMS? Perhaps you meant to talk about CSM which stands for Compatibility Support Module.

    Yes, I was on a 2*6 pin on the old one and now a 2x8 pin.

    Considering the number of times I’ve plugged it in and out, I don’t think I inserted it badly, but I’ll redo the test.

    Would be unlucky if it’s the problem anyway, especially since it’s well powered, the fans are running and the LEDs are on. I don’t have a second PC to test it, it’s a hassle.

    Thanks for the info

    Hello

    No, not under Peripherals tab.

    In the graphics card section I have an AMD Radeon R9 200 series (so my old graphics card)

    If I install the new one, I won't have any display because I think it isn't recognized by the PC; on my monitors it says "HDMI output not recognized" so I won't see anything.

    I used the AMD cleanup utility to remove my old drivers but the same: it doesn't work. (that's what AMD told me to do)

    I updated it, I’m clearly on PCIe for the graphics slot. Then I wouldn’t know what to look for…

    Not recognized therefore it is impossible to open the Device Manager since I have no display.

    I'm at a loss, I admit it, and AMD doesn't help me much more.

    There is only the 3 left, the rest is fine, I checked again at noon.

    I will test the new graphics card on another PC tomorrow, we’ll see... for once it would be bad luck given the price, but at least I would be relieved to know where it comes from. I’m out of ideas.
