    Computer won't boot with 2 monitors connected


    Hello. Recently I have changed my GPU to Sapphire RX 570. I have two old monitors with VGA connections. Previously I used to plug my second monitor to motherboard and my main monitor through HDMI-VGA adapter to my GPU. Since my new GPU have 2 HDMI connections and im usually watching something while gaming on my second monitor I wanted to reduce load on my CPU and bought new HDMI - VGA adapter. Its a bit different than my other one. Once I connected second monitor through adapter I was able to see that two monitors were working on extended mode quite good but it only lasted for around 1 min. After that both monitors went off and were displaying no signal. It went on bootloop. I could see through both monitors while it was loading through bios and even while windows were connecting to user account. But once spinner with account name were almost finished boot loop started again with both monitors showing no signal once again. Basically I cannot boot my PC to Windows when both monitors are connected to two HDMI slots in my GPU.


    Things I have tested:


    Run both monitors separately for a few hours only on new HDMI - VGA adapter. Both monitors worked fine


    Reset BIOS settings to factory defaults


    Boot into safe mode then connect second monitor


    Remove and reinstall video card drivers


    Reinstall windows


    Change HDMI adapter slots / change monitor slots


    Update Windows


    Take out GPU and reseat it again


    Restarting multiple times

    :)

    i have a problem to connect 2 monitors.

    Hi Ron,

    Thank you for posting your query in Microsoft Community.

    • What changes did you make in the BIOS? As making the changes in the BIOS is only recommended by Microsoft if done by the manufacturer.
    • How are you connecting to the 2nd monitor?
    I suggest you to follow the steps from this article below:

    [Applies to Windows 10 as well]

    Regards.
