System fails to power on or access BIOS settings.
Hello, you're experiencing issues with your PC that have persisted for three years. After applying a Windows update, it fails to boot and displays only a blank American Megatrends screen. The motherboard lights up the boot LED but nothing else appears. You're unable to access the BIOS or perform any diagnostics at this stage. Are there steps you can take to identify potential causes? Thanks for sharing the photo—apologies for the low image quality.
I took it a step further by disconnecting additional components from the power supply. At this point, both the drives and the graphics card are unplugged. I was able to start a Linux system via USB, but the MB no longer displays any status lights.
Hello, thank you for your feedback. Initially, I couldn't reach the BIOS because of some cables still connected. Luckily, I was able to boot Linux, which suggests the main drive might be the source of the problem—perhaps from a recent Windows update. I plan to try accessing and resetting the BIOS now. I just want to make sure the update didn’t affect my primary storage.
