r/buildapc on Reddit: Everything seems to work fine but red VGA light is on
July 4, 2023 -

Specs:
Mobo: Gigabyte B650 Aorus Elite AX
CPU - Ryzen 7950x
GPU - MSI RTX 4090
RAM - G.Skill Trident Z5 Neo RGB 2 x 32 GB DDR5
PSU - MSI A1000G

So here is the problem: I just finished building my pc and everything seems to work, I got it to post and everything in the BIOS look correct, it detects both SSDs and the PCIe slot that the GPU is in. However, the red VGA light on the motherboard is on and I don't know why. My worst fear is that either the GPU is dead or that the PCIe slot has been damaged, but I feel like if that was the case, they shouldn't be detected and show up in the BIOS (please correct me if this is wrong). I have checked both ends of the 12VHPWR cable that connects the GPU to the PSU and they are tight. I also had the click when I inserted the GPU into the B650 so that should be properly secure. All of the lights on the GPU light up so clearly it is getting power. I've also done the BIOS update for the mobo and the VGA light is still on. So now I don't know what else I should do. Is it something to do with the GPU drivers that I have yet to install or something like that? Any help, info, or advice would be greatly appreciated, thanks.

Are you able to boot to desktop? The VGA light usually means there's a problem with the graphics card or the output device. A few things you can try: Swap out your display cable for a new one or using different ports on the GPU and your display. This is often overlooked but might solve the issue. Make sure your output is plugged into the GPU and not the mobo. Ensure the GPU is seated all the way, and that the clip is not loose. Ensure the GPU power cables are all plugged in properly, especially if you are using the splitter. Try reseating the GPU as well just in case If you're able to get to desktop, try installing the GPU drivers. If you don't experience any other problems, then I personally wouldn't worry about it.

June 7, 2021 - I've tried an HDMI connection to a different monitor I've tried different VGA power supply cables. I have tried resetting cmos. I've disassembled everything and put it back together. No change I have also put together my old set up with the new PSU and the GPU is recognized no problem. I've also used a completely different set of RAM. No change. The parts should be compatible, right? I've not seen any issues there, but I might be wrong. So far, it seems the motherboard is the culprit or maybe I am wrong?

tried (in the case your CPU has an iGP and you had the display cable plugged into the GPU) plugging into the display output on the motherboard and seeing if integrated graphics works ... Cool. Thanks. Going back to your op: I heard that this light usually has something to do with the GPU · Are you certain that the light which turns on is next to the "VGA" label? (there are printed labels next to each debug LED) There are 4 debug LEDs right next to each other (CPU, DRAM, BOOT, VGA) and all 4 of them are red on your motherboard.

i have a problem when i turn on my pc VGA light stays on and no boot but when i wake up my monitor my pc boot fine (but that don't always work) and sometimes i press the reset button and it works but it used to boot and wake my monitor just fine i tried everything i tried to change my display port cables i changed my motherboard i changed my psu and nothing worked but when it turn on my pc works fine and i game with no problems

specs
R5 3600x
nzxt n7 b550
rtx 2070 super
psu coolermaster v850i gold

I have the same problem and a number of departments have confirmed that the problem is in the screen because when the computer starts up, the motherboard checks all the parts and makes sure there is no problem, and when it reaches the VGA stage, it discovers that there is no screen due to the screen being delayed at the beginning of operation. To avoid this problem, turn on the screen first and then turn on the computer.

R5 3600x doesn't support integrated graphics.

That's why the VGA yellow led is on and your monitor won't work.

Old motherboards had onboard integrated graphics so they won't need special processor to work. The situation changed since the new motherboards don't have integrated graphics, hence you need to rely on the CPU for this function. But as you know, is about money, producers found a way to skim the market, specially NVIDIA, who first entered the GPU market and since then, they have the monopoly.

Anyway, installing a GPU circumvent the problem. I would not purchase NVIDIA due to their monopoly, and the fact that they set the price they wish. Instead, I would try Intel GPUs. Intel has recently entered the market, I I believe that their prices are competitive.

Cheers.

September 4, 2024 - The VGA light on a motherboard is a diagnostic LED that lights up when the motherboard can’t detect a graphics card or can’t communicate with it effectively. If the light stays on, this is a sign that something’s not right with the video output from the computer to the monitor. Each motherboard manufacturer like MSI or ASUS has its own system for LED indicators. For example, an MSI motherboard may show a solid white or red light, while ASUS might have a blinking light.
