The surge likely damaged the power supply, causing the error you're seeing. The ASAX Steel Legend B450 with a Ryzen 6 CPU might be affected by such issues. Consider checking for other signs of damage or contacting support for further assistance.
Your keyboard might be sending the key for Instant Flash, possibly with a quick shortcut like F8 or F10, or the BIOS could be damaged and require a new BIOS written via programmer. Avoid pressing keys while starting the computer. You can download the latest BIOS, unpack it onto a USB drive (format it fat32), insert the drive, and try again if the issue persists. Instant Flash will recognize the USB file and may prompt you to program it.
