ASUS motherboard features VGA white illumination plus a green boot light that stays on solidly.
Hi everyone, I recently assembled my first PC and everything worked fine at first. During the initial boot, I encountered an issue with the VGA light on the motherboard, but resolved it by removing all RAM modules and leaving just one in the A2 slot. After that, I was able to access BIOS settings. Now I successfully installed Windows 11 and booted into the desktop after updating via the M2 SSD. I left the computer idle on the desktop so Windows could complete its updates in Settings. Once the updates were downloaded and installed, it required a restart. After that, the process stopped, and now the computer won’t boot at all. The VGA light is still blinking white solid, while the green BOOT LED appears. There’s no signal on the monitor. According to the manual, a stuck VGA light usually indicates a GPU problem, but I don’t think so. Despite having an M2 SSD inside, the system doesn’t recognize it. My specs are: Ryzen 5 5600X, AMD RX 6600 Eagle (Gigabyte), 8GB RAM (ASUS TUF GAMING B550-PLUS), Kingston Fury 32GB RAM, 750W PSU (switched from 550W), Crucial P3 Plus 1TB M.2 SSD.
What I tried:
- Swapped RAM sticks
- Removed the GPU and used a different PCIe slot
- Reset BIOS and CMOS (including removing the battery)
- Updated BIOS via ASUS Flashback, but it didn’t work
- Tried disabling CSM in BIOS for Windows 11 installation
- After resetting CMOS, the system restarted back to defaults
I’m unsure what caused the problem. Could be a software glitch after the update, or possibly a GPU issue despite the manual suggesting otherwise. It’s been two days of troubleshooting, and I’m still confused. Any advice would be greatly appreciated!
Have you explored another GPU model? The boot indicator will turn off if the system fails to load a storage device. After checking all previous solutions, the only remaining suspect is your GPU. Would you mind confirming whether the GPU was bought new or previously owned?
Feel free to mention a brand new setup—no refurbished or recycled parts. Would it help if we check the GPU before opening Windows? I used to run on Desktop, Edge, and YouTube, but after the Windows updates I restarted my PC and noticed this issue. I don’t have another GPU available.
The VGA Light indicates a problem with the GPU, preventing the system from displaying properly. It might stem from a faulty display cable or monitor, but more likely the GPU or motherboard is defective. After trying various solutions, you should consider swapping in another GPU. If the issue persists, the motherboard could be the culprit. ASUS has recently faced quality concerns with their AM5 boards.
You should check this as part of troubleshooting. A faulty HDMI cable may trigger the VGA light and prevent proper display. For older monitors, switching to a new or verified cable/monitor can help.
I visited the repair shop a few days ago. I'll share the issues I encountered and wrap up the topic soon.
They mentioned a GPU issue might be the problem. Changing GPUs resolved the issue, working smoothly with Windows and proper drivers. After shutting down and turning off the VGA light, the screen still didn’t appear. Any suggestions? It seems to work better with another GPU. They recommended replacing it.
The system functions properly on another GPU but encounters issues with this one. Simply swap it out. If the advice from them aligns with your findings, I support their suggestion.
