Fix ASUS Anti-Surge was triggered to protect system error during boot in Windows 11/10
ASUS Anti-Surge is a protection feature on some ASUS motherboards that is designed to protect the system from unstable power supply and power surges. When a power surge is detected, the computer shows the “ASUS Anti-Surge was triggered to protect system” message on system startup. If you cannot boot into Windows due to this error, use the following fixes:

- The PSU may be faulty
- Reset BIOS
Let’s start.
1] Check the power supply of your home
The problem may be with the wall socket. It might be faulty. To check this, connect your PC to another wall socket in your home and turn it ON. If the error screen does not appear this time, you need to change the wall socket because it can also damage other electrical appliances in your home.
2] The PSU may be faulty
If the above fix does not work, the PSU unit may be faulty. The error message also shows that the Anti-Surge was triggered due to an unstable power supply. Take your PC to a professional computer repair shop to test the PSU of your system. If it is found faulty, consider replacing it.
3] Reset BIOS
You can also reset your system’s BIOS to the factory default settings and see if it helps. To do so, enter the BIOS and find an option to reset it. Before proceeding, note down all the BIOS settings, so you can reapply them after resetting the BIOS. Different computers have different keys to enter the BIOS. You can refer to the user manual of your computer to know the right BIOS key.
That’s it. I hope this helps.
