Question: No signal with new graphics card?
Question: No signal with new graphics card?
So I received a new 9070 XT Nitro+, replacing the 3070. I installed the new GPU but it’s not working properly. The boot process is starting and the VGA light remains active—suggesting the GPU is seated correctly and receiving power. I swapped the 3070 back in to test, and the same problem persists now. I’m uncertain if the board was damaged during installation because it was quite challenging due to its size and weight. I’ve done a new RAM reseat, verified all power cables, and even tried re-seating the GPU, but it still doesn’t click as it did with the 3070.
Updated, I changed the bios and now the CPU light is on, while boot and VGA are disabled.
Can you access the BIOS? Are you certain the graphics card is properly placed in the slot? Perhaps re-seating the CPU might resolve the issue, as it could have been shifted during installation. If none of these steps work or you have no further advice, consider rebuilding the PC outside the case using a cardboard box. This method is known as breadboarding the PC, which can help identify any assembly-related problems.
I attempted to re-seat RAM, the CPU, and changed the CMOS battery.
The PSU stopped working, so it was replaced.
Returned to the old GPU, the motherboard fan is running, the GPU fans are also active, but the CPU light is on, the cooler isn’t working, and none of the fans are spinning.
I really don’t know what’s going wrong here.
Updated status: Repeated flashing of the BIOS now resolved the issue. The CPU indicator has stopped lighting, and both VGA and DRAM lights are active while the CPU light remains off. The motherboard fan is operating at full speed, the GPU fails to power on, and the power button does not shut down the system—requiring manual shutdown via the power source.
I'm using a specific technique to flash the BIOS. I assume you're talking about either the CPU cooler fan or the chipset fan. If you press the power button for more than 5 seconds, it should cause a shutdown. If not, there might be an issue with the motherboard. Have you tried booting without a graphics card installed? Although you won't see a display, you can still observe if the behavior changes noticeably.
Flash using a button on the board.
There is a fan on the mobo, possibly the chipset fan, not the CPU fan—I have an AIO.
I haven’t tried rebooting without the GPU.
I also think the motherboard was damaged when I tried to seat the GPU. However, I eventually managed to get it seated properly.
Here’s what you should do to diagnose it yourself, otherwise take it to a repair shop:
1. Obtain an AM4 motherboard that meets your requirements.
2. Update the BIOS to the latest version on that board.
3. Reset the CMOS.
4. Place the RAM, CPU, cooler, and graphics card outside the case in the motherboard box.
5. Attempt to power it up. If successful, install your storage and check if the system boots.
If the new motherboard resolves the problems, test the previous PSU to verify it’s dead. I believe the old RMX PSU might still be functional. When starting the PC for the first time, allow sufficient time for the RAM to initialize. This may take a few minutes and can appear as the system is inactive or producing errors.
