VGA display visible yet functionality restored post BIOS upgrade.
VGA display visible yet functionality restored post BIOS upgrade.
Hello everyone, I'm here discussing an unusual problem that started after updating my BIOS. It's been a couple of weeks, but I've been experiencing strange issues with Roblox—sudden crashes without any error messages. After researching, I discovered my BIOS was two years outdated, which led me to believe it needed an update.
Following the guidance, I performed the update. However, my PC didn't boot properly at first. I checked the motherboard and confirmed the VGA lights were on. I tried disconnecting the display port from the GPU to connect it directly to the motherboard. This action triggered a message about FPTM Firmware, instructing me to press either N or Y.
I initially pressed N, which brought me back to the BIOS menu. After rebooting, the same prompt reappeared. I repeated the process, pressing N twice before finally accessing Windows. Once I rebooted again, the message vanished, and the boot error disappeared.
However, the VGA light only lit up when my Display Port was connected to the GPU during startup. If I disconnected it and only used the HDMI cable, the PC booted normally without any lights. I can reinstall the GPU afterward, but if I restart with it plugged in, the VGA light comes back on.
Here are the details of my setup: Motherboard – ROG STRIX B550-F (WiFi); Graphics Card – GTX 1070; CPU – Ryzen 5 3600X; RAM – 32 GB (2x16) at 3600MHZ (set to 2155 due to motherboard limitations). Components came from Corsair.
What I attempted:
- Tried reverting to an older BIOS version (3403 → 2423).
- Removed the motherboard battery for 5 minutes and reinserted it.
- Removed the GPU, cleaned the connector, verified all connections, then set BIOS to boot with the optimise option.
- Considered reinstalling the CPU (Asus website suggested), but wanted to explore other fixes first.
Important note: I only changed or removed something in the PC before the BIOS update. Today was the only modification—just unplugging the GPU to clean it up.
Another observation: After some time, both displays eventually worked, though it took longer and I lost access to the BIOS when the Display Port was active. The HDMI port didn’t trigger any lights.
Thank you for your assistance!
