Display issues appearing with a black screen and red VGA light.
I recently assembled most of the components for my PC and haven’t managed to resolve the red VGA indicator problem on both the motherboard and graphics card. I installed a new motherboard, CPU, RAM, case, and cooling fan for the GPU. The old setup had the GPU running smoothly just a few days prior, but it’s only been about a week and a half. When the system starts with fans active, the GPU doesn’t function properly—just lights up. Plugging in the mouse triggers it to light up as well. Specifications: Motherboard B650 AORUS Pro AX, CPU Ryzen 7800X3D (8 cores, 16 threads), CPU cooler EK Nucleus AIO CR240, GPU ASUS TUF GeForce 4080 RTX, RAM G. Skill Trident Z5 (2x16), DDR5, PSU EVGA Supernova G5 750W, case DeepCool CK560. Estimated power draw is around 606 watts, which should be sufficient. All connections were reattached carefully; the GPU was removed using pins and sockets cleaned. I tried a replacement GPU (MSI GeForce GTX 1660 Ti) but it still shows the red light. Need guidance on possible solutions.
Red VGA light indicates the machine stopped during post-processing while testing the GPU. It doesn’t necessarily mean a faulty GPU, but it suggests the issue might be related to the connection. Verify that everything is securely connected and properly installed. Repeated attempts can sometimes remove any dirt from the connectors.
I completed these changes. Reversed the RAM positions and then flipped them back after testing. Updated the HDMI cable, relocated the SSD to a different slot, and the PC started up successfully. Adjusted the BIOS to use legacy CSM support, and it appears to function properly. The GPU fans activate only when necessary. I’ll keep an eye on any issues and update as needed.
What type of SSD are you using? Please specify. For drives over 2TB, switch to UEFI mode instead of legacy. Here’s a quick guide:
1. Create an installer USB with Windows Media Creation Tool; ensure your PC is running Windows.
2. Remove the SSD from the machine.
3. Connect the USB stick and enter BIOS settings. Change boot mode to UEFI and set the boot device to the USB. Save changes and power off.
4. Insert the SSD into the appropriate slot (likely M.2). Restart and launch Windows installer—your drive should appear. Let me know your progress.
