I finished building my PC recently. when I turn on the monitor when the computer isn’t on, there’s obviously no signal and I see the bouncing logo, but when the computer is on, it says that there is no signal, and that my monitor is going into standby mode, and the display turns off. my gpu seems to be working fine, and I reseated my ram. What should I do?

    Does the motherboard have any LEDs? If you don’t have a motherboard speaker, the motherboard sometimes shows LEDs to display an error code.

      It does. I notice that the CPU light turns on briefly but turns off. Is that bad?

        You should lookup your motherboard manual or something to see what the LEDs mean. From what you say here, it sounds like the POST might be failing due to the CPU. Maybe try reinserting the CPU.

        It could also be that it posts but then it should display and let you get into the bios. So not sure. It’s hard to diagnose without more info.

          The light means that the CPU is not detected, but it turns off quickly

            Try reseating your CPU, check the pins to make sure you didn’t bend one. Taking some photos and zooming in can help you get a better look.

              According to the manual all of the lights are supposed to turn on briefly.

                Sorry got busy and work. Any luck? None of lights stay on?

                If not I would just double check and reseat everything, and for shits and giggles pull the cmos battery for 30s and put it back, if you haven’t already.

                If nothing else works I would be thinking about RMAing the mobo.

                  Only the boot light stays on even though I have a boot device. (And am trying to boot into bios)

      The boot light turns on, which according to the manual means I don’t have a boot device, which is weird since a) I’m trying to boot into bios, and b) I have a fedora USB plugged in
