How to fix error error-bios-failed-to-connect-interrupt in Windows 11

Solution Steps

1. 1 Restart your computer and press the key to enter BIOS setup (often Del, F2, or F10). The key is usually displayed on the screen during startup. This allows you to access low-level hardware settings.
2. 2 In the BIOS, look for settings related to 'Interrupt Request' (IRQ) or 'PCI/PNP'. You may need to set 'Reset Configuration Data' to 'Enabled' or 'Yes'. This clears the previous interrupt assignments and lets the BIOS reassign them.
3. 3 If you recently added new hardware, ensure it is properly seated in its slot. Turn off your computer, unplug it, and reseat the hardware. This can fix physical connection issues.
4. 4 Update your motherboard chipset drivers. Go to your motherboard manufacturer's website, download the latest chipset drivers, and install them. This ensures the operating system can properly communicate with the BIOS.
5. 5 If the error persists, consider resetting the BIOS to default settings. In the BIOS, look for an option like 'Load Optimized Defaults' or 'Reset to Default'. Save and exit. This can resolve configuration conflicts.
6. 6 After making changes, restart your computer and see if the error is gone.
